Title: KZ 750 Twin - Two point zero
Post by: canyoncarver on Feb 08, 2016, 22:11:10
  Here goes.  I've been interested in the KZ twins for awhile but never owned one until a few years ago.  I mean hell, it's bigger than most of the 650 twins of it's day and it's even got dual overhead cams.  Only two cylinders and carbs, what's not to like? 

  So about two years back I picked up an 81' KZ750M1(CSR) version to play with but those are the old jap cruiser style.  I messed with it for awhile (provided me with spare engine and many parts) as a side project but I decided not to fight that geometry and look for an earlier "B" model instead. 

  The KZ750B is a 76'-79' bike and has a more standard geometry than the 1980 and above versions.  They are a rare beast around here but a few weeks ago I found a decent but fugly 1979 on CL where the PO had given up on his ill-fated cafe attempt.  PO is a nice guy and had the right paperwork so the bike ended up in my sons' truck.  This is where things hopefully start looking up for the old beast.  This one won't be a restoration, not a cafe, lets call this a resto-mod.  I'm going for a period-ish modified rider with this one.

Plan:  [IR/R]  Inspect, repair, and replace.  Upgrade where necessary or fun.

The very first thing I did to the bike?  Remove some fugly seat mount ideas.
Title: Re: KZ 750 Twin - Two point oh?
Post by: canyoncarver on Feb 08, 2016, 22:14:25
The PO had a cafe tail and body work painted.  Not my style at all but the paint was nicely done.  The tank is factory clean inside which was a nice change from most project bikes.  The tail won't be used and the tank will get new paint.  I'll probably trim the sidecovers, they are huge.

Standard crusty stock stem bearings.  I have the Allballz tapered set already.  In the previous pic, there were cheap clip-ons on forks lowered in the triples.  That didn't stay either.

Roughly where I am as of this past weekend.  I have a different tank on it while I'm mocking up seat stuff. 
I spent most of it up to my elbows cleaning and degreasing.  It's my least favorite part.   The rear sprocket carrier cleaned up really well though.

I have two good sets of carbs for the bike also.  The ones on the left are the 79's and the right are the 81'.   I built the set for the 81' from ebay salvage and some new bits inside.  The 79's are in nice shape and with a bit of cleaning will be good to go.  Also, shop cat Saki says hi.

A bunch of stuff on order, not enough but stuff that will help me move along.   I'm putting together a good size order to Z1E.  Also trying to source some local services like sandblasting.   Started cleaning up the forks and the triples, getting stuff ready for paint.  Some color options are still up in the air.

Cleaning up the swingarm.  Bearings and bushings are all good but looks like I should figure out something better for a chain slider.

Get a chunk of Delrin and have it bored out to the pivot tube diameter, then fish mouth the inside edge. When you bolt the swing arm in it is entrapped. I did this on my kz1000

Thanks man.  Thats a good example of one that would probably slip right on.  I'll dig around, that one was UK and didn't want to ship over the pond.  I might bug one of our "has a functional lathe" friends to turn down some Delrin.  I'll look to see where I can find it in colors.

eplastics.com was a better deal.  A foot of 2" dia black delrin is on the way.   This "might" help motivate me to get my lathe motor mount done so I can turn this stuff myself.

Moving another stalled project up the list next to the KZ.    The other project will help with this one (at some point) . Moved the lathe and bench across the garage so it's in my way and I'll have to finish restoring it.  New motor mounts and variable speed motor control is the plan.  Needing some Delrin sliders got me thinking.

Still at it, just struggling to get some time in the shop.  Had the shovel out for a short ride the other day, gotta fix some stuff there too.  Mrs needed some help to keep her projects from turning out badly.  Had to change gears to her stuff for a few days.   All good.

Thanks guys.
About the lathe,  I've been talking to more experienced brains and I decided not to try and restore the old motor mount system and just go with a good variable frequency drive setup.  I've ordered a few things, need a few more.   I've ordered parts to build a tach setup and next is sourcing a good 3 phase motor.  I have the VFD picked out and will order that this week.  I still need tooling, quick change post, etc...   


Between bike parts for my chopper, ZRX, this KZ, and this lathe, and the big new garden, my resources are getting stretched.   The springs for the KZ came yesterday even though I ordered them same day as the springs for the ZRX.   Brake seals are in but only two.  I need to catch a break.

Forks are still giving me problems on disassembly.  Those lower allen bolts!  I tried loosening the bolts out before removing the spring caps, no dice.  I've been trying the pointy broomhandle trick, no dice.  Lots of pb blaster in there and I've been trying heat too.  One of them loosened up a bit and I can't get it any further.  Major issue is that the broomhandle just doesn't get enough grab in the round hole down in the fork cylinder.   These are the round holes, not the easier hexagonal ones.   I don't want to have to buy that damn special holder tool unless it's really necessary.    I'll get it, this is just a rant.   Unless there is a trick I haven't found?

Dude, I did the broom handle trick, then put a 200 psi impact to mine and stripped one of the bolts. I had to have a machine shop drill it out. You might drill it out yourself, if you feel brave.

I couldn't believe that bolt was so tight. That drilling cost me an astronomical amount...machine work ain't cheap.

did you carve the broom stick round? I like to think i have this shit down to a science ::) I taper the broom stick as much as possible and leave the sides square then add tiny grooves in the corners like a broach, but not too many or very deep. Then spray a crap load of brake cleaner down the fork to get the rod a clean as possible, gently tap the broomstick in until you feel it bind. do not let the fork go horizontal or all that crap will wash back and loosen the bite. i have never not gotten a set of kz forks apart like that

Take a large diameter dowel (or a broom stick with the end cut off) and place it in the fork tube. Secure the leg in a vice. Take a ratchet strap and wrap it up over the protruding end of the dowel.  Crank it down. Place your driver bit onto the bolt and using a metal hammer, give it a few good metal to metal to metal raps. Then place your dewalt (use only a 20V XR brushless) and reverse it out.

Thanks for the inputs guys.  The "fancy" diesel, impact driver, and my new tool worked like a charm.  Broomstick just wasn't doing it so I tapered the end of some metal rod and it a tap or two held it nicely.

After sitting on this project for a few years, I'm pretty excited to get it moving.  My new motor and VFD arrived along with some good reading material for restoring vintage lathes.  I also have the lcd tach setup for it, proper 10k ohm rotary dial, lcd sensor, and a bit more.  I was waiting on the motor before I tried to fab up a mount for it so I hope to start that soon.  I want to build a good switch/control head/box and find a way to mount the VFD unit.  I'll try to not make it all look like hokey crap either.  I feel fortunate to have friends with much more experience in this than I do.  It is also a great source of motivation. 
Plenty to do before metal spins though.  Onward.

I hope so.  Depends a bit though.   I'm thinking solo seat on the bike and Mrs. wants to come with me to Barber this year.  I may end up trailering two bikes if so.   More room inside for disco lights and a good subwoofer box in RedVan1.

Maybe consider the "g" side covers. Much smaller than the "b" side covers. Cool to see another 750t build on here.


I've been looking for decent ones but they still get a bit of a silly price on the bay'.

Front brakes have been held up until I got this:  New stainless aftermarket front brake piston.  The original leaked and has seen better days.


I also picked out frame paint color and it's not black.  Well, I have 3 cans of it at least.  Plan is to pull the engine out so I can begin finishing up on the frame.

Are those pistons the same size? maybe its the angle or something. I have read that if you use sintered pads with a non-insulated piston they will get hot enough to boil the break fluid. Im going with Phenolic pistons in my 750.

Doc, the dimensions are identical, it's a wierd angle.  The only difference is the thickness in the lip around where the piston contacts the brake pad.  I had not considered the phenolic ones you posted, I appreciate the link.   I paid 35$ plus the ride for the stainless version. The phenolic version is a bit more but I wonder what the difference in weight and heat tolerance is?


I'm going to run this one but i'll keep an eye on it.

I have been doin some research into a couple options for bigger pistons.
The YFM350R has a 19mm wrist pin and the 83mm overbore pistons available for it would bump the 750t to 865cc. the pistons look very similar to the stock 750 pistons and can be had for pretty cheap. i dont know what this would do to compression.
http://www.ebay.com/itm/Namura-Piston-Kit-2004-2013-Yamaha-Raptor-350-YFM350R-Standard-Bore-83mm-/291774199439?fits=Make%3AYamaha%7CModel%3ARaptor+350

I personally would really like displacement to go over 900, and at this point it looks like custom pistons would be the way to go. 86mm pistons (8mm over) will give you 906cc. Someone on here tipped me off to Arias pistons, and when I contacted them they gave me a rough estimate of $150-$200 per piston with rings and pins, they have a minimum order of 4 pistons. discounts for volume. I have a junk motor that i need to pull apart to get some measurements from so i can get an exact quote. the upside of this is you can have them made exactly how you want, probably to work with the megacycle cams 8)

L.A. Sleeves has universal flanged sleeves that arent too expensive. they would be need to cut to length. I don't think you could go much bigger than the than the 86mm pistons because the sleeve has an OD of 92.3mm and the flange is 95.5mm. the flange would have to be trimmed down to not butt into the clyinder studs.
https://www.lasleeve.com/tech/all-purpose-sleeves

then there is the issue of a head gasket
Title: Re: KZ 750 Twin - Two point zero
Post by: Nebr_Rex on Jun 22, 2016, 22:38:41
The Raptor piston looks interesting. Would probably need to be resleeved and a head gasket, maybe copper.
I'll check with the local cycle shop, they work on most of the quads around here.
Another option is to go to a plated cylinder. Might not be able to go much over the stock sleeve diameter.

8mm over to 904cc sounds wild.  I like the idea but I also read a few things about taking these motors too far.  Something about the balancers, etc.   I'll try to dig up the thread references.  They were from older stuff on kzrider and somewhere else.  I'll give Megacycle a call and see what they say about the cams and what they might have tested with them.  I like where all this is going.

If you find anything about the balancer having issues I'd be keen to see it. I have read some vague mentions of that, but I have never seen a someone with an issue yet. A guy over on the lonesome-twin site is putting in a big bore kit and his pistons/pins weigh the same as stock. You can also run without the balancer, but you would want to get the crank balanced for sure then.

I called Megacycle today.  I talked to a very nice knowledgeable lady.  She knew a fair bit.  They can make new ones for the KZ 750 twin for 425$ per pair including your core.  About 8-10 days turn around.  The profiles they recommend are different than what you find on their website.  I'll have to call back to get better info on that, we got cut off for some reason and it was nearing their closing time.  It sounded like they have some race knowledge with the cam profiles for the bike.

I love ads from back a ways, classic stuff.   I picked up a set of ebay cams for cores to send off to Megacycle.  I'm trying to wait a bit until I get some more piston stuff figured out.

Doc, I know you were talking biggest bore option but I don't think I'm going to build this one as hot.  I'd like to be in the 810-850cc range with a streetable but hotter cam.  I haven't got solid numbers on the street cam profile yet either.

As much as I would like to do the 86mm bore I think an 83mm bore would be the best for reliability and clearance issues in the cylinder block. that puts you at 865cc. Im veryinterested to hear what megacycle tells you.

That sounds very do-able.  Stock bore is 78mm at 8.5:1 compression.    What are you thinking in terms of valve changes if any, heavier springs?
Title: Re: KZ 750 Twin - Two point zero
Post by: doc_rot on Jul 03, 2016, 23:58:47
Definitely gonna need some heavier springs for the megacycle cams. I was going to have the head flow tested, but I'm guessing that like most of the UJMs the valves are too big to start with so an increase in cc's will probably have the stock valve sizes be just right. The one big incentive to have custom pistons made is that they can be higher compression to compensate for the loss of compression the new cams will cause.

If somebody had a stock 750b piston to get the wrist pin to top of piston measurement.
I could possibly find an off the shelf oversize part that might work. Had a similar quest with
a 2.0 over 440 jugg. The search is like a drug for me, finding solutions for mechanical problems.

If somebody had a stock 750b piston to get the wrist pin to top of piston measurement.
I just picked up some solvent for my parts cleaner so i will start the tear down on the motor this week and can get that measurement.

That looks super clean and well done. It has the GS1100E swingarm which is about 2" longer than stock. NOt sure what the front end it off but it looks quite a bit lower than stock. what are they asking?

I buy 5 gallon buckets just labeled "solvent" at the local auto parts store. smells like lacquer thinner.

If somebody had a stock 750b piston to get the wrist pin to top of piston measurement.
I could possibly find an off the shelf oversize part that might work. Had a similar quest with
a 2.0 over 440 jugg. The search is like a drug for me, finding solutions for mechanical problems.


.

20.88 + 9.5 = 30.38mm. It could be 30.5mm, these calipers are cheap and not super reliable.

let me know if you need anymore measurements. I really appreciate your help on this Nebr_Rex.

Thanks!  It's plain old florists green foam blocks.  I used a 3m spray adhesive to glue them together about 8 hours before I started cutting away.   I used a grater for wood for the rough out and my hand worked really well for fine stuff and smoothing.  I wore a good filter mask, that stuff goes everywhere.

Yep, that's where I'm putting the rocket launcher assembly.  Well, maybe the next build.....
Once the form is finished, I'll have the line I need to notch the extra rear frame tube and bend it upwards about 70 degrees or so.  I'll weld it up and it will end up being a support for the back of the seat.   Thats the plan at least.

Aluminum tape.  You're right Hurco... I just need to finish it.  I've been trying to get the wax on there so it will actually work as a release agent.   We just put a deposit down on a 12x20 shed for the back yard and that prep is keeping us busy at the moment.

I had a free day during the weekend so I got on the seat glass project.
I got two layers done and decided I could finish it better off the bike.  Let it set up about a day and a half
then I took my time and peeled the whole deal off the frame.  My "release agent" strategy worked really well. 
Oh....I'm never going to used chopped mat again, that stuff is awful once you go to brush the resin on,
stringy mess all over.  The woven mat was much easier.  There is still a ton to do, sanding and a few more layers
of mat and resin to beef it up.  It should be simpler now that it's off the bike and I can do other stuff with the frame as well.
Cheers.

An experiment but lesson learned!  Getting the resin/hardener ratio right was interesting.  I just eyeballed small quantities at a time.  It was outside on an 80 degree day.  It gave me about the expected 10-12 min working time.  I need more acetone around next time for cleanup too.

But only in one direction.

Chopped mat is equally strong in all directions, though it is weaker than woven 'glass in it's stronger direction.

The mat is better for curved pieces whereas woven is better for flatter surfaces. Mat is also the correct choice when doing patch work.

When using chopped mat the best method is to dab the resin on, then when you put the  woven down you can brush it out smooth.

I have built wood/fiberglass boats and worked with people in the composites industry, so i've had an inside look into this stuff. My buddy's last company built fiberglass and carbon parts for the America's Cup boats.

Chop mat is for fiberglass tubs. Woven mat is for calculated structural applications,(the same concepts apply for carbon fiber). Sonrier is correct about the strength in a single direction, but that is where planning your layers comes into play. You can use 4+ layers at 40*, 90*, and 120* from the original layer in order to resist deflection in multiple directions. The pro's have math and formulae they use to plan out the layout of the layers of glass, I personally just wing it and have been fine. The fenders on the 360 consist of 3 layers of woven 6oz mat at 0*, 45* and 90* and there is hardly any deflection in any direction even when torquing with your hands.

If you're going with a few layers of chop mat, it will work just fine.

Oh and try using a roller with chop mat

I was talking per layer. And like adventurco points out, you alternate direction with layers.  The same goes for most structural applications of any grained material.  It's basic physics.  When layering wood for ply, you alternate direction of the grain for strength. 

As far as "correct", it also depends on what you're using as an epoxy.  Some wet better than others.

Fiberglass rollers are a must for the mat.  I also work a lot with varying strands from 1/2" to 4" in sculpture, so no mat or cloth.  You can make your own with stacked washers, or even coating a tiny brush roller with epoxy...

105 resin and 206 hardener. The smaller sizes should run you about $70 for both. Totally worth it, and you will have them around for a while. Add in a tube of 410 and you can mix a few spoonfuls in with your epoxy mix and it makes a super strong and easy to sand filler. You can likely just lay a few layers of 6oz cloth over what you have to help smooth the surface before filling.

Also bonds much more tenaciously to more substrates.  Costs a lot more as well but you get what you pay for in this case.  One thing to consider is that epoxy is very pleased to be used on top of polyester resin composites, but remember that once you do, you don't want to go back to polyester as it does not bond well to epoxy.  Not usually an issue on small bike parts, but it can be an issue for people doing things like repairs to boats.
As a rule I only use chip brushes and squeegees myself as most of the parts I make are principally cosmetic and don't need to be either ultra strong or ultra light.  Seems to me many seats or seat bases are a lot heavier than necessary because the builder feels the need to make the part more structurally robust than needed.  Most bikes have a heavy steel frame directly under the seat, so if you design the glass work to fit or be supported well by the frame it can be extremely light and thin and still be very durable.

Post by: jpmobius on Nov 14, 2016, 19:38:46
That looks fine for cloth.  Unless your building an airplane, your most important criteria is ease of working.  You can make the whole process more complex, and in fact, if you are really going for performance, it is.  That said, you can make VERY light and strong parts with very minimal wherewithal with a little planning and a couple of tricks.  99% of the time, I use very light glass CLOTH and epoxy resin.  I recommend using the same despite the rather large price in cost of the epoxy.  I think it is a lot easier to use, and is much stronger.  I very rarely use molds (only if I make something really complex and have strong belief of using it again.  Really good molds are super expensive if you make something complex) and never use gelcoat.  Go to a marine store and get the lightest cloth they have - they should have "finishing cloth" and buy this epoxy here: http://www.epoxyproducts.com/noblush.html  (http://www.epoxyproducts.com/noblush.html).  The fine cloth is easy to use and makes extremely strong parts with a few laminates.  You can make damn near anything with these two materials. 
The first "trick" is to make very careful and accurate foam models of what you want.  The best thing to use is styrofoam (picnic coolers and cups are not actually styrofoam but expanded polystyrene which will NOT work!) but it is pretty pricey.  Urethane foam is very good also but sometimes hard to find (try an industrial insulation vendor) but green florists foam is fine if a twinge expensive.  Take whatever time it takes to make a perfect exact size model of what you want, and then sand it a bit smaller - whatever thickness of glass you want in all dimensions.  Then you simply laminate glass layers over the form and you have your part.  I often use polyester body filler (regular ol' Bondo) to glue foam together and mount blocks temporarily to a frame etc.  I build lots of parts right in place - right on a bike frame for instance but you have to comprehensively mask off EVERYTHING within several feet of where you are working unless you are psychotically neat.
Likely you will come up with a shape that has compound curves and the cloth will strongly resist smoothly conforming to the shape and you will wish you had bought chop strand mat instead.  Stick with the cloth unless you want crazy heavy and weak parts! There is a solution.  The second "trick" is to carefully cut out your pieces of cloth so they will lay flat on your compound surface.  This means you will have to cut wedge shaped reliefs in various places to avoid overlaps and/or use multiple pieces to fit over your shape.  Cut all the components you will need for the session first and take your time to do a precision job.  You can leave extra at the edges, but time spent here will pay heavily when you lay them up.  To make them stay in place, mix just enough epoxy to paint the surface of your foam form.  don't allow ANY epoxy to get on your cloth laminates.  Once the epoxy has started to "kick" (don't wait too long) it will be very sticky and you can lay on a layer of cloth and smooth it out flawlessly with a credit card squeegee.  It might take a little fussing, but as the epoxy cures it will eventually very tightly bite on the cloth and not let go.  The epoxy needs to be sticky enough that it doesn't soak into the cloth.  You can get PERFECT smooth layers that flawlessly conform to the craziest shapes this way.  Once you are sure the layer of cloth will stay tightly stuck in place you can mix up some more epoxy and saturate the cloth.  Don't worry about the wet epoxy - it will not soften up the first painted on layer and let your cloth go.  Epoxy is not a solvent and fresh batches will not dissolve an earlier batch that has started reacting.  Squeegee as much epoxy back out of the cloth as you can, and wait for it to get sticky just like the first painted on coat.  Then you can stick on your next laminate of cloth.  Then saturate and squeegee the excess.  Repeat until you have the thickness you want.  You can use this same technique with polyester resin if you want to save some money, but you should at least try the epoxy and decide for yourself.
The foam is super soft and you can easily carve, scrape and sand it out of your new part after the epoxy cures.  Many epoxys take rather a long time (like polyester resin does) to keep a really permanent shape despite seeming totally hard and cured.  So if you make something like a seat pan, you should think of leaving the foam intact and your part on your frame etc for a week or so so it keeps its exact shape.  If your part needs to be hollow, you can cut an access hole or cut it in half, scrape out the foam and then epoxy the joint back together with a recess and a couple of strips of cloth laminated over the joint.
After you are done and satisfied with the part you can fill the weave of the cloth with a filler mixed with epoxy (as previously suggested) and sand it flat to a paintable finish.

This seat/tail section was made in this exact way, is very strong and weighs less than 2 pounds.  You can see the green florists foam is still inside the tail piece.

Just go to Home Depot or Lowes and get insulation foam.  Pink at the Depot or blue at Lowes.  You get a hell of lot more for the price, and it sculpts better.  No need to go to a specialty industrial place and its much better than florist foam. Oftentimes, strand works better for complex shapes, especially when working over a buck, ie a mold (which is what the foam is).  You can also thin coat the surface of the foam with joint compound and sand it super smooth so you have a perfect surface.

If you want something that acts similarly, but is much stronger, there is a material called  Aqua-resin (http://www.aquaresin.com/).  It's a very opaque plaster-like material that gets very hard and has a similar cured hardness to fiberglass resin.  I've been using it to make castable positives for years.  It's nice because of it's hardness and zero toxicity.  Here's an example of a master made from insulation foam and Aqua-resin...

Thanks Beach!    Glad to have you onboard.    I've got a bit of momentum back on this one after setting it aside for the winter.      I have a set of KZ1000 mag wheels I picked up that I'm considering going with.  I prefer a rear disc to the drum but it would mean (to me) building new rearsets.    Still thinking about that one...

Is that a diaphragm pump? They're not really designed to pump hot oil.  It will work for some amount of time, but not sure they can be trusted over time.  Also like Matt is pointing out, unless you upgrade the charging system, a vintage bike really can't support an electric oil pump.

They're often sold as oil pumps, but I think they're designed for marine fuel? It'll be interesting to see if the seals hold up to the heat. Most electric oil pumps designed for hot oil use (turbo scavenge pumps, etc) are not cheap. About $300 when I was pricing them before.

Just a headsup on the pump.

£50 DELIVERED in FOUR days. From one of the "preferred" provinces [ thanx for the tip ].
Very robust, well made and HEAVY ! Somewhat bigger than the KZ starter motor.

Yes gear pump as pix and designed for Marine use - but now touted for "turbo scavenge" - increase the market eh ?

Yes on the current draw - and to reiterate this is a stand by "plan C". AND I' still nervous about a pump / electric failure whilst in use.

No loss, if I go [ hopefully ] with the Gixer pump, then the Chinabay pump sees use on my Supercharged Volvo 940 Estate project.

It's a good question Beach/Doc.  I have a points setup and a later ignitor style setup.  My earlier motor will get the newer ignition setup.  I had not thought past that. I'll have to look up the C5 now.

I have heard good things. one bummer that I realized when installing it the other day was that you loose the ability to turn the motor over with that side of the crank. I haven't set the ignition to TDC yet because of this.  It was impossible for me to get it to TDC with the kicker, the compression its making is too much to be precise.

Rather than throw away grenaded engines I kept them less innards for set ups and "whatifs".

CC,

It looks like I will be building TWO bikes now. I can't face another year [ running out of time !! ] without a bike on the road.

Realistically the Glemseck project is probably 12 months away - funds mainly as I do not want to cut corners.

However , the original Tangerine Dream project is pretty well there funding wise - with milder approach engine wise. Just the Weber conversion, high level pipes and with the cosmetics already pictured I have virtually everything I need.

The Glemseck bike is definitely morphing into a bit of a dual purpose race / road machine, and as much as I would like another set of Grimeca hubs etc, I can't afford it - so that means either swap wheels back and forth [ ! ], or make a decision as to which bike gets the Grimeca / Borranis and the "something else" for the other !

I do have a spare frame / swingarm coming courtesy of Kaptain Kwack over on the Lonesome Twin forum - in addition to a late engine complete with twin plug head [ eventually ! ] - well actually 4 plug, but you know what I mean !

So the plan is to move the "TD" off the bench and on to the build ramp and put the Glemseck project on the bench - but just as a frame / engine combo to set up the oil cooler. external oil pump, turbo, Nitrous etc.

That's where the alternate fork enquiry comes in. KZ 750 Twin parts are ferociously expensive here in the UK - and even with KK's sympathetic pricing - still adds too much to my meagre funding pot.

I'm not really a fan of rear discs - aesthetically, and in truth I very rarely use a rear brake !

So that's my dilemma I guess, I would love to have one last 60's style Cafer Racer, but the Flat Tracker can be finished that much sooner.

Yeah, it's tough, I'm building two bikes at the moment as well.  One always takes resources from the other no matter which one you are talking about.  It's why I keep my ZRX "on the road" and my chopper will be back on the road soon too.  Having something to ride keeps me motivated.

I have my 750 forks that I likely won't be using, if you are interested send me a pm.  They are currently disassembled but in good shape.

Airtech stuff is very nice for a reasonable price. Guess it depends how much you value your time. It will take a lot of time to whip that tail into shape.

Yeah..... so I talked to Walt at Airtech.  Super nice and helpful guy.  I have this seat on order, about two weeks out.   I mentioned I'm interested in his stuff for my YZF750 project he got excited and we talked about those for awhile too.  The 96' 750SP plastics they make are sweet.

It's the closest shape I liked that will fit my frame.  AdvCo is coming by my place next weekend.  He'll get to laugh at my attempt and maybe even show me how to fix it.  I have the stuff to start over and try again which I'd like to do later but the airtech seat is now plan A.

The only thing that I've heard is that the airtech stuff might take a little more prep prior to painting but that's it. Still better than starting from scratch.

I probably will start again from scratch on a seat for it at some point but yep, I wanted a faster, nicer plan B.

I started to get the kz brake parts together.  I had most of 5 calipers in process of cleanup when I remembered I bought that 1980 KZ1000B roller awhile back, I got a box of parts with it.  I went and looked and it had all the kz1000 calipers to go with the 7 spoke mags for this build.  They all need a rebuild and new lines but I call that a win.  It might save me from some rear wheel alignment issues as well since the rear caliper and right side spacer are a single unit.

This is curious to me.  The pistons on the KZ1000 calipers look externally the same as the 750's but the pistons are very different:  750 on the left and 1000 on the right.
Title: Re: KZ 750 Twin - Two point zero
Post by: canyoncarver on May 06, 2017, 23:25:46
I know the difference on the piston types now.  I just had not seen them before.  I think these are what you meant when we talked pistons way back in this thread Doc.

So I'm also trying to figure out rear sets.  I have a spare set off a ZRX1100 wondering if I want to use them here.  I didn't use the production green zip ties since this is just a mock up.  ;)

I took basic measurements of the YZF since stock it comes with clipons and the seating position relative to pegs and bars works well for me.

The primary difference between the two is the YZF has a 3.5" longer reach across the tank to the bars. 

I would still need to build a mounting plate for actual rear set placement.

Thanks.  I think next is making mount plates from 3/8" plywood for each side to validate the setup and come up with what I need to either make or have them made.

I wish I could tuck the rear sets in where they are zip tied now.  There just is not enough swing arm clearance.

Eliminate the heel guard mumbo jumbo and attach to the frame. Done.

If you want a heel guard, go off the tube.

The brake spring and switch are in the way of the swingarm as it sits in that pic.    I only need about 1/2 inch more of clearance, what I have in mind for the mounting plate should take care of that.  As for the heel guards, hmm, still thinking.

Nothing exciting to report but I'm still at it.  I got some good garage time today at least.  I cleaned up a ton of chassis hardware on the wire wheel.  I also cleaned, sanded and cleared the rear sprocket carrier for the KZ1000 mags.  Next is a bit more frame cleanup.

Not sure on the bore size, the rear is always a single disc so I'm going to give it a go.  I don't have the number for the caliper piston size handy either.   I'll look them up.

If you need, I have a spare one Doc.
Title: Re: KZ 750 Twin - Two point zero
Post by: doc_rot on Sep 13, 2017, 22:16:05
sometimes the bore size is stamped in the body of the casting. I am still undecided on the rear caliper i want to use and that will dictate the bore size I need. I think the stock KZ MC is 5/8ths. most newer bikes use small single piston rear calipers and need a much smaller MC. but like you said, try it and see how it works.

Here is the closeup of the rear master.  I'm using a very similar rear caliper to yours, mine is off a kz1000.

J-Rod is making me up some folding rearsets so I started on a template that fits both sides of the bike.     Once I get the mounting holes where I want them I'll clean up the design a bit.

Oh boy ........... one very happy Beachcomber here !
Twin plug head is completed and awaiting my collection [ with the rest of the '81 engine ].
The good news is that the guy who did the deed for me borrowed the relevant jigs from the instigator - and was then given permission to duplicate the jigs for his own use.
He won't be creating a production line anytime soon - but has the wherewithall if anyone's interested ? The only problem is that he no longer has access to his machine tools etc. as he's changed jobs. However, he is getting a quote from a local friendly machine shop to see if it's viable to get the conversions done.
I have decided on the Norvil 1/2 fairing.

Progress looking good CC ! I recently went through the caliper / brake refurb game - only to ditch it all with the swap to the Grimeca and XS650 drum rear . I'm following your rearset installation with interest as my bike is [ has ! ] morphed into that 60's Cafe Racer now rather than a Flat Tracker. Keep those pix coming - inspirational !!

CC ... this is my actual head. The small damage to the exhaust port exit floor has been rectified. The other pic is of his "prototype" - notice there was some small damage to the casting around the milled hole.

One of the German KZ guys [ Michael ] and a.n.other have twin plug conversions and both have offered up options for ignition. My pal is busy doing another head at the moment [ now he has the jigs ], but has to look for a machine shop as he he is changing jobs and won't have facilities to do it himself at the new place.

As soon as I have positive info for the twin plug ignition I'll let you know.

Still working on it.  I got the new neck bearings and races in and done and was able to mount up the front end.  Now I can work on the headlight and gauge mount stuff.

I cleaned up the peg mount template I made and it looks like it will work how I want.  I have 3/16 steel plate.  I'm pretty sure it will be enough, if not, it'll be easy enough to re-fab one with 1/4 plate.  It'll be bolt on and not welded so no permanent frame mods for the new rearsets.
The shift linkage lines up nicely but the trick will be the rear brake pedal linkage.  I have an idea but not 100% yet.

I would say 3/16" is totally adequate - unless you intend to stand up on the pegs ! Even then ...................

A favour please - could you give me a measurement from the vertical oblong boss on the gearbox [ viewed above sprocket ] to the centreline of the primary drive sprocket ? I want to roughly 'ish set up the rear wheel for sprocket alignment. My dummy engine has no guts in it. And I don't want to handball the complete lump around if I can help it. Ta

Many thanx for the pix / measurements. One final - if I may be a PITA.  ::)

Here's the point I need the drive sprocket to rear sprocket alignment measurement from. IOW - I need to know how far out from the casing the sprocket c/l is. That's just so I can roughly position the rear wheel and sprocket to get spacers made. I'll allow for shimming for true alignment once the "real" engine is in the chassis. Your second pic down showing the drive sprocket from above is virtually it, but you can see on my dummy engine - I don't have that outer case where the drive sprocket is !
