Title: Coffee Shop KZ650
Post by: flip_rip on Jan 11, 2017, 16:03:59
Hey Guys!

Starting a new thread for my KZ650 project. The idea behind this one is to create a very minimal KZ650 that is at home cruising down to the local hipster coffee shop with a lady friend on the back, or ditching that idea and hitting the canyon roads balls out and getting its lean on! I want it to look sick in any location, whether its DTLA or in the hills above Malibu, or at full lean on The Crest. The overall look I guess is a bit of cafe and tracker vibes, with an emphasis on road performance.

I am really picky about how a bike rides, and I want this one to strike a balance of performance on the twisties but not be too uncomfortable to ride up the coast to SF. It needs to be versatile and I for sure want to take it out on date nights.

The NX is almost finished and I think that will turn into my dual sport/lightweight baja adventure bike, and will hopefully have a vintage supermoto wheel setup in the near future. So the KZ is more road mannered.

The PO had visions of making this bike some kind of cafe racer and has since stripped out most of the handle bar controls and did a whole bunch of weird wiring things. Also it doesn't run and has no spark...but for $500 with a clean title and registration until Jan 2018 I feel like I'm doing okay.

I'll be keeping it super minimal, so no turn signals, no brights (just one bright headlight setting), no air box, hidden battery, ideally some trick hidden switches for the kill/starter.

I'll chop and loop the frame and de-tab as needed, but I would like to keep a version of the stock duck tail, I really like how that looks.

Up in the air right now are wheels/tires. I though about maybe taking the rear rim and lacing it to the front hub and doing either an 18f/18r wheel setup with a 18x2.15 in front and 18x3.5 rear, or going to an 18x2.15 front and a 17x3.5 rear to gain that better tire selection. I'm also not opposed to keeping the stock 19/18 wheel tire setup, but there seems to be only one or two sets of sticky tires in those sizes.

I'll rebuild the front forks with calibrated spring rates, and will upgrade the rear shocks. I was thinking of going a tad longer with these to give it an agressive stance, but not take away from how it handles.

Lightweight is a goal, but not a rule. I'd like to keep it quick and lively and shave some weight, but I'm not looking to drill speed holes in everything haha.

First up is replacing the whole ignition system to the DynaS and green coils and upgrading to a 3 phase reg/rec unit. Then a manual cam chain tensioner (the chain is rattling in there and I'm really hoping its not more than just a bad auto tensioner). Then I'll remove the head and do a full port and polish job with new valve guides and seals and seats, and shim accordingly. All but cylinder 4 have compression above 175psi, cylinder 4 is at about 125psi. More detective work lead me to leaky valves, hence the head work. I'll probably skip the full top end rebuild for now, as it only has 17k miles on it. Of course a carb rebuild and jet is on the list, but recently finding more info on the Keihin CR29s has me pretty intrigued....I just know know if I want to drop $1000 extra on it yet haha.

New paint, LED lights, a hella black magic headlight, new gold chain, sprockets, gauges, pegs, Renthal bars, fork brace, and a custom seat will round out the package.

As always, photos for days of everything will follow this and hopefully I'll leverage insight from fellow KZ riders here!

Oh and I was able to put this bike into the back of my Trooper without a ramp haha! Its already been and adventure with this thing!

 17 wheels have more of a tire selection and are going to be lighter which has a big effect on accel/decel, but you give up ride height on a bike that needs it.
18 wheels will keep ride heght and can be pretty light if you get aluminum rims. The rear rim is drilled for the drum brake and the angle of the spokes will not work for the much smaller front hub. It's best to get a rim drilled specifically for you. But if you found a rim for a similar sized hub you could probably make it work with custom spokes. Personally I think the bigger wheels, while being a little heavier, look great on these bikes and if you plan on really getting it leaned the ride hieght is important. You will find the limit of the bike before the limit of the tires with a mild engine. if you are replacing both rims I would go with a 18/3.5 rear and a 18/2.15 front. Running a 130/80/18 rear and a 100/90/18 front using BT-45

If you want to upgrade the chassis I would do so in this order of importance:
Shocks
Cartridge emulators in the stock forks
Stiffer swingarm/ oversized close tolerance pivot
Close tolerance engine mounts.
Braced frame
Fork swap

Also I know you didn't ask for this but my only advice for the styling is remove the rear fender and ginormous tail light and just stare at it for a month. Hard to beat that seat/tail for 2 up riding...also side covers aint too bad either...  just saying ;D draw your own conclusions
Title: Re: Coffee Shop KZ650
Post by: flip_rip on Jan 12, 2017, 14:26:32
Haha I really appreciate the input! This is awesome! We'll have to see on the tail/side covers. I'm for sure not opposed, but I think the seat is a bit thick for my taste haha.

Thanks for the heads up on the wheels. I'm back and forth. At this point it'll be keeping the stock wheels and find sticky tires, or going to exactly what you suggested, aluminum rims, new spokes in the 18x2.15/18x3.5 and go to a full tubeless setup. That will be the lightest setup, but also will take a bit of work. Also I completely spaced the drum brake rear, so the spoke angles and holes will be different. Might need to flip a coin haha.

As for shocks, I have a few options, mostly looking for input on shock length (and in turn ride height). Stock is 13.5, so do I go 14, 14.5? Any experience with this?

I might start looking into a whole front end swap since I'm leaning toward changing the front wheel anyway. That way I can play with the forks, and front wheel at the same time, and maybe even upgrade the braking system. I don't think I need a dual setup, but maybe a larger single rotor and bigger caliper.
Title: Re: Coffee Shop KZ650
Post by: doc_rot on Jan 12, 2017, 17:53:34
A fork swap is a easy way to get better brakes, lighter wheels, and better suspension for sure, but there are a lot of factors that need to be considered when selecting new forks/triples. Not to mention quite a bit of modifications that need to be done to do it "right". That was why it was last on my list.
If you want to swap the forks, in my opinion, you need to upgrade everything else as well. The problem is that modern forks are much stiffer and typically shorter. By lowering the front of the bike and decreasing the rake you are putting much more stress on the head stock. So while you have much improved suspension in the front you cant fully utilize it because the rest of the chassis is forced to be much more flexible. If you look at my kz1000 project you can see the great extent I went through to reinforce the head-stock and brace the frame to deal with the load that a stiffer fork and swing-arm would translate to the frame. oversized close tolerance motor mounts to tie everything together are a help here as well.

Again, it really how you see yourself using the bike. if you just want a cool bike to cruise on that's one thing, if you want to improve is functionality that's another. To do a fork swap and get the most out of it you must approach it as a complete redesign. That means considering all these variable at once, wheel/tire size, fork length, fork offset (very important). triple tree height, swingarm length, wheelbase, and shock length.

Stock rake/trail for the kz650B2 is 27į/108mm

Modern Superbikes are usually around 24-25į and 95-100mm of trail. It is inadvisable to go much below these figures.

So to answer your question on the shock length; if you are keeping the stock wheel size, you can go up to a 14.5. it will make the bike a bit more twitchy but it will turn quicker, and it will gain ride height.
If you start changing other variables like the forks and wheels, the shock length must be considered as well, so I would figure out how deep of a transformation you want to go and then decide on shocks.

Also with lightened rotors, sintered pads, and a 15mm brembo MC for the 38mm calipers the brakes on the 650 are pretty good. depending on traction and body position I could "stoppie" my old bike. I just put the same setup on my buddies 650.

Here's my opinion, which should mean little, because it's your bike and your $. I don't understand designing a bike that throws every bit of road debris and weather directly at all your hard work. I'm a huge fan of the KZ650 and it's styling. I agree the back light might be a little HUGE, but the fender and tail piece look great, and an abbreviated front fender would look cool. Other than fenders ( I think KZ650 look great stock) I think the middle bike on the right (with fenders) would look great, and yes a tad thinner seat, maybe a small aluminum air lip above the head light.... It'll be interesting to see where you take this project...
Title: Re: Coffee Shop KZ650
Post by: flip_rip on Jan 13, 2017, 19:44:51
Haha thanks guys! I really do appreciate the input. I agree with fenders, but I think there is a way to shorten the tail of the bike and still maintain that ducktail feature without it looking like its sticking way out there. I did a very rough chop job of what I'm thinking for the rear. But with a thinner seat. See how its moved up? Tracker style at this point, but it doesn't hang way off there. Since I'm modifying the frame anyways I think I can just slide everything forward and integrate the seatpan to sit a bit further back to accommodate 2 people. I think I like the idea of side covers, but it might look sweet with the short ducktail and no covers too....hmmm need to start chopping metal!

Doc - what rotors/brake setup is that? Is that from an SR? I'd like to keep the stock solo rotor, and have already planned to do an SS line and MC upgrade. Good to know the 15mm Brembo option is out there.

Its the factory dual brake setup, that is found on the KZ650C/D kz1000B,  the disks have been thinned and drilled by Goddfrey's Garage. The 15mm MC is for dual 38mm calipers. If you keep the single (IIRC its 41mm) caliper you will need a different size master.
Title: Re: Coffee Shop KZ650
Post by: flip_rip on Jan 17, 2017, 01:18:01
Gotcha gotcha. Thanks for the info! I ended up going with a 14mm MC and a braided line from galfer. I also went a little wild and tore into the bike to figure out exactly why it isnt starting....turns out the PO must have left a spark plug out during a rain storm or something because the inside of the #4 cylinder was very very rusty. So I pulled the head and the cylinder block.

I was able to snag some new old stock KZ pistons and a ring set off ebay for cheap. My other option was to do the wiseco 700 kit, but I want to keep the stock carbs and I think a 700 might be on the upper end of their performance. So now I'm off to find someone to do new valve seats, clean the head and re-hone the cylinders. (most look pretty good, but the cross hatching isn't what i was hoping for)

I also order all new gaskets, a sweet new headlight, clutch pack, clutch cable, grips, a new throttle, pod filters, oil filters, and I decided on my handlebar switch setup for the clean look.

I made the decision to keep the stock wheels and just clean them up. It would be cool to do a smaller set, but I came across the Continental Classic Attacks, and will be putting on a set of those.

Fork rebuild is still on the list (maybe stiffer springs) and for sure new rear shocks with appropriate rates, but I need to get this thing running and on the road before I start making any suspension changes.

There is a ton to do, but I need to finish stripping the frame to repaint it and get the wheels and fork clean and fresh. Then motor rebuild, carb rebuild, make a seat pan, rewire the bike, get some new tires, and the other few odds and ends to get this road worthy! The ideal plan is to have it running by mid feb.

Also my roommate gave me a sweet idea to make the ducktail into some kind of removable cowl to make it a 1 or 2 seater, so I might take on that challenge instead of totally chopping up the rear of the bike. I'll detab it but I don't think I'll do a whole new subframe like on the NX.

So hopefully UPS and Fedex and USPS are good to me this week and I'll have about 50 packages to dive into this weekend!

Photos of how I ended my weekend attached!

Title: Re: Coffee Shop KZ650
Post by: doc_rot on Jan 17, 2017, 16:33:49
I'm curious to see how those conti classic attack tires end up feeling. I have the conti road attack II on my Aprilia and love them, they are supposed to be very similar.

The reason why the stock seat is so long is to accommodate 2 people. I think where you have the tail sitting right now looks awesome, but you ain't getting two people realistically on a seat that size. In the early iterations of my kz1000 I thought about having two separate seats; one for single and one for 2 up. I ended up scraping that idea because there was too much compromise for me, but ill be interested to see if you pull it off.
Title: Re: Coffee Shop KZ650
Post by: flip_rip on Jan 17, 2017, 17:17:27
I'm interested too. Ive heard good things about the conti's. I'll post up a quick review when I have some time on them.

I know there will be some kind of compromise, but I'm looking forward to checking it out. I think right around a 24in seat length is the min for a 2 up. Maybe 22 if you have a small person on the back, and as it sits in the photo, thats about 20. So hmmm. I challenge for sure!
Title: Re: Coffee Shop KZ650
Post by: doc_rot on Jan 17, 2017, 17:20:50
also im worried the fork stanchions hiding under those gators are rusted to crap. have you peaked under them yet?
Title: Re: Coffee Shop KZ650
Post by: flip_rip on Jan 17, 2017, 17:28:29
I have and theyre not awful. I was pretty worried too after seeing how corroded the engine was, but it seems this was the only thing the PO left on to protect something haha.

I'll still pull and rebuild them while the frame is being painted. Then once the bike is all running, I'll start fiddling with tuning them to match whichever shocks I decide on. Little torn between some YSS, Fox Podiums, maybe some TECs. I'm not sure. It would be ideal to get something that is at least adjustable.
Title: Re: Coffee Shop KZ650
Post by: flip_rip on Jan 24, 2017, 15:29:36
So the tail is finished. There isn't a good way to do a removable cowl on this simply because the whole assembly sits under the seat, not over it. I stared at it for a good 2 hours before I decided to just re position. I decided on a 22in seat length. This means the seat ends at the rear axle, and the ducktail goes to just over the edge of the rear tire. I'm not too concerned with following the BikeEXIF cafe racer rules haha. It should be plenty of room for 2 passengers and the lines of the bike still look really good. No need to totally throw Kawasaki's designers ideas out the door!

I got the engine out and cleaned the frame. I drop off the head and cylinders with new pistons and rings this Saturday to be machined and honed. I'm sticking with stock bore diameter, but shaving the head to increase compression a tad. After some clean up and paint the motor will be ready to go! I got the new Dyna S system on order along with the 3 phase reg/rec/stator upgrade.

So all my parts should be just about in. I got the new head light soft mounted, so now I can start to paint the triples. Then just need to paint the frame. All the fab work is done on the frame. I de-tabbed and re-positioned the rear ducktail and fabricated new mounts for it. I also made mounts for the new seat and battery box to fit in. I decided to not keep the side covers. They just make the middle of the bike look bulky. Not a fan. Although before you go too crazy on me....yes there will be a fender to protect the back of the motor. I have a neat idea to keep things minimal.

Lots of parts came in this week, just need to get the frame and forks painted and I can start assembling everything!

I think I may end up putting on longer shocks (current are 13in (330mm) with 80mm of stroke), but I'll wait until the motor is back in to start figuring out how tall I want it to sit, and how much it will affect handling. That may be a very last step.

But here it is as it sits! Also rebuilt the carbs last night with all new internals. Slowly making progress!

I'm not sure if you can see from the photos, but I used the mount where the brake light switch used to sit in the middle of the lower triple. There are 2 forward facing holes, so I just made one of these little adapters from a piece of angle aluminum.

Not my photo, but that is what mine ended up looking like.

I'm just going to run that light with a 100W bulb. It has a spot beam pattern and is fairy bright with my first test fit. I'm not planning on blinding anyone haha but I'll be on the edge of legality...

I see lots of guys doing this on the off road forums haha so it'll be an experiment.

And the shop is Lucky Wheels Garage in Los Angeles. They have a really sick setup! I'm doing both my builds there since my apartment won't let me work on stuff in the parking garage.

Post by: doc_rot on Jan 25, 2017, 02:31:48
I like the seat position. its a reasonable compromise, while still looking cool. Heads up on that headlight; even with the 3 phase system i'm not sure the bike can support 100w sustained draw for the headlight, are you planning on running signals? I forget exactly but I remember reading something like 80 watts was the highest you could go on the headlight. the OEM one is 50/35. I guess you could run it and find out, but if shits acting weird that's one of the first things I would look at.

Don't get rid of the covers just yet... every now and then just put one on there and take a gander and think about how cool it would be among one of the trailblazers of the "side-cover renaissance". haha. just contemplate.
Title: Re: Coffee Shop KZ650
Post by: flip_rip on Jan 25, 2017, 12:48:29
Thanks! I think the seat will turn out pretty solid. I looked through just about every photo of KZs on google and decided I couldn't totally get rid of it.

Good to know on the headlight beam. I won't be running turn signals on it. I was curious about the 100W upgrade. I might stick to the stock 55 (that came with the new headlight) for now, and see if it makes sense later. No reason to burn up the whole system. I guess I could go to an 80 if its really dim, but I don't see it being a huge issue.

Haha the side covers are still in the parts box. I'll hang onto them just for you Doc....for now....

If you do run turn signals fitting LEDs is fairly easy.  The only difficult part is adapting them to fit the the large openings of the existing fork ears and headlight bucket.  Same for rear.

This is what I did.  Buy K&S Turn Signal Stems for KZ(http://a.co/4Zr9BhJ (http://a.co/4Zr9BhJ).  Cut the tips off, then drill and use a Tap & Die on open to your aftermarket LED signal threads.  Then you will just need two LED flashers relays from CWS Wiring Solutions. http://www.cwswiring.com/Shop.html (http://www.cwswiring.com/Shop.html)

A good replacement headlight for the stock lamp is the Wagner Halogen Sealed Beams H6024.  https://www.summitracing.com/parts/WAG-H6024/ (https://www.summitracing.com/parts/WAG-H6024/)

Take a look at my thread.  I put on a Wiseco K700 Kit, Cams, Oil Cooler, etc.  Happy to answer any questions.

Oh solid! Those look pretty good on there!

One issue with the bike is that the previous owner stripped the wiring harness of just about everything except the head/tail lights and starter switch. So I'm working off a minimal harness. I was originally going to just buy a whole new one, but I want to keep things pretty minimal on the bike, so right now the plan is no signals/hazards/brights switches on the bars. Just a kill/starter switch.

Ah man but I should at least make it legal.....ugh I might just wire in what is needed for the signals and decide at the end if I want to add them.

I've looked into the m-units but man they are spendy! The Eastern beaver option looks pretty good!

I ended up buying a flexible LED tail with integrated signals in it, so I'll wire those in with an upgraded relay for the LED flasher.

Decisions decisions...It's turning into a bit of a money pit haha, but I should have the engine back next week! I got the new Conti tires installed, frame painted, and all the controls and headlight mounted. New braided brake line, and master came together awesome and feels great just rolling it around the shop! I can't wait to get this thing on the road!

The dyna S ignition and green coils came in along with the 3 phase rec/reg, so as soon as I get the motor back in I can get it all wired up! Hopefully since just about everything on this bike is new, it will come together smoothly....but I doubt it haha.

Anyways. Next week I'll make the stainless batterybox and seat pan. I was able to get it all mapped out. Just need to decide on a seat layout. Not sure if I want the bump for the passenger further up, or pushed all the way back. Leaning toward the thinner setup.

Photos following! Let me know what you guys think about a seat setup.

Have you considered a longer swingarm? Maybe only +1 but somewhere in the +1-2" range would really balance the bike out. Also keep you from flipping with all that new power

Post by: flip_rip on Mar 10, 2017, 13:49:19
Been a bit since I updated this but I made some major headway on the KZ.

The motor is back in the bike and has all fresh new parts! New pistons, rings, clips, valves, guides, seats, head was shaved by 0.020" and everything is ultra clean! Boyko Racing really helped me get the head all sorted and cylinders honed. I shimmed the valves (I cant believe the range for all valves is 0.08 to 0.18mm! I set them all at 0.10 to be safe) and got all new gaskets and mating surfaces cleaned. I installed all new stainless bolts so there wont be any more rusting on this motor and torqued to spec. All new polished hardware and motor mounts so everything looks the part. The new stator for the 3 phase system is done and wired in with the new 3 phase reg/rec unit.

I rebuilt the whole wiring harness in my apartment last week and made sure it all lined up properly with the Dyna S ignition and 3 phase charging system. I just need to drop it all in the bike now!

I'm hoping to get the wiring all hooked up and running properly this weekend so then I can start the bike next week! Still need to drop off the seat to be upholstered but, but thats about all that needs to be done.

Cant wait to get this thing running! Its nice to have fresh new parts haha! Pics Pics Pics!

This bike got good reviews for it's handling back in the day, I wouldn't put a longer swingarm on it just for looks.

I've read that too. I've kept everything stock for now as far as fork and shocks go. I'd like to preserve the stock geometry. If anything I've just made the whole thing lighter so hopefully it'll be a hair more nimble bike.

Well I'm like 98% there! Everything is installed and working properly together!

I got the new jets installed (17.5 slow, 118 mains per all the forum scavenging I've done) but it seems it just doesn't want to idle. Not enough fuel getting to the motor. The petcock is the new vacuum one from Z1, have any of you guys had issues with enough flow?

Its been a few months since I cleaned the carbs, so I might go through and clean them again, make sure the float height is sold and do another bench sync. Its literally just a carb tune away from running! Ah dang!

fork brace is on the list, but you don't need fenders in CA haha!

I'd "spring"  for some new shocks too. The factory ones are horrible. Looks good.

I agree with Doc. Those factory shocks will literally Spring and jolt you out of your seat. I got Progressive 14 series on mine(oil), standard spring rate.  They are great for my weight (170); however, I kind of wish I got the 12 series (nitrogen). Standard spring rate is good for minimal load. If you weigh a lot more and/or will ride with a passenger often go with heavy duty spring.

Hagons are the other brand that KZ650 riders swear by.

 I agree with the Hagons, have bought several and they work well. Also, I've said this before, it's your bike and $, but why design a bike who's sole purpose is to pick up every piece of debris and throw it at your art. Fenders can look good and serve a purpose.

I agree and you can tie the fender in with paint as well.

Wow guys. It has been a while! I figured I would update everyone here since the build is COMPLETE! Yes, complete. I have re-done everything and now this bike absolutely RIPS! It feels good knowing that its all wrapped up.

Highlights include:
-CR29 carbs (YUP!)
-Starter upgrade (went to the one way bearing from the ZX bikes instead of the clutch system)
-New clutch/basket
-full wiring harness upgrade
-cleaned up controls
-lithium battery
-rear tail painted and polished

It rides like a dream and is super fun to rip around town on. I attached all the photos I have of it, and a few of the 'in progress' ones because everyone likes a happy ending to a build thread, instead of the OP ghosting everyone!

Also I have a ton of pics here if anyone wants to see all the photos in one place:

Looks great. Those carbs are the business. Any motor upgrades? If you think it handles well now, get yourself some shocks and a Tarozzi fork brace and you will be amazed at the transformation, the kz650 is a great handling bike.

I did have Teddy boyko do the heads and we raised compression to around 12:1. New pistons and rings but thatís about it for the motor. Wanted to keep it fairly stock for reliability. And I know I know.....shocks and a fork brace would be ideal! But itís looking like itís going to a new home soon, so Iíll encourage the new owner to tinker.

Well done sir!  Looks incredible!  That headlight looks like it's floating, excellent!

Tell me about those CR carbs.  Did you get a chance to compare performance to the stock VM24s?  If so, where did you feel the difference?

Thank you guys! Really appreciate the kind words!

I did not ever get the VM24s to run right, even after multiple rebuilds and tunes. I can say that the CR29s are amazingly smooth but if you open them up itíll scream! I notice that the throttle response is crisp and that it just wants to be ridden fast haha.
