'81 TR1 build.................(yup another Mojave tank combo!!)

[znviper6]

all made by me.......

Ah nice! Wish I could get my hands on some of those. Building an XV750 right now and they look awesome!

 

[Hurco550]

Glad I stumbled upon this build. Very neat, and nice workmanship! Following along!

thanks, just wish I had as much access to the CNC stuff I find on your great build......... 8)
saying that, I'm not too badly kitted out, just gotta use what you've got eh!!!

Thanks man! Unfortunately I left my machinist job to teach welding full time at the local JVS, and no longer have all the CNC equipment available that I did =/ I have always said I make up for my lack of skill with CNC equipment. Good news is I may end up teaching some of the new machining program here at the school next year, and who is to say some of my "demonstration parts" may not just happen to fit a 1974 CB550..... Looks like you do very well with what you have to say the least. Craftsmanship may not always show to everybody, but it shows to fellow craftsmen.

Neat mounting on switches.
How waterproof will they be though (I see your somewhere in Wales)
I'm from Bridgend area

 

[lchris21]

It don't rain here in Wales................ ;D Just down the road butt, in Neath.

This puppy will not be seeing much rain when its on the road. They're only controlling horn/main beam so no biggie if I get caught in a shower, just dazzle the oncoming drivers and nice blast of the horn to go with it !!!

 

[crazypj]

Know Neath a bit, worked in 3M Motorycles Swansea for a couple of years (before Mount Motors took them over and laid me off Dec 23rd 1990)
Delivered a few bikes there.
Worked for UK Plant when the roads were being dug up for fiber optic cables as well.
The good old days ;D

 

[lchris21]

Been busy the last few weekends so not had much time on the project. couple of small updates................

Have been working on mounting the various electrical components ready for making up the loom. Horn, relays, rectifier, plus other bits and bobs....

Also finally found a location for the oil pressure switch mod I planned. This took a lot of head scratching to find the best place.

As we know full well, this engine was designed with an oil level sensor only, and had no provision for a switch. there's a few threads on the web about running extra pipework, drilling the oil filter housing, shoving in small gauges here and there, but I decided to try and keep it neat and simple. Found a small oil gallery on the front head cam feed, picked up a small pressure switch online (think it was an old British Leyland spec) rated to 0.8bar, so plenty of warning if I start losing pressure. Drilled the head in place with some strategically placed bungs to prevent the swarf getting in where it shouldn't.


Same time I took some meat off the bulky brackets supporting the engine and rear sub frame...

 

[lchris21]

looked all over the web for some velocity stacks for my Minkuni carbs, but they were like rocking horse poo....or really expensive. So started messing round on the cad, modelled one up, and printed out a plastic test piece. When it looked right I got a local CNC shop to make a pair for me. I could have done it manually but would have taken 10 times longer and I hate machining aluminium with all that stringy swarf !!
Got hold of some stainless mesh to complete the job....

These ain't been flow tested on a bench or anything, so are purely pose value at the local cafe :

I've got some proper filters from weekend blasts.....

 

[lchris21]

the rear brake pressure switch I was going to use was not playing ball when fitted to the master cylinder, it was a bit too close to the swing arm, so I had to get hold of a small sealed micro-switch and mount it down on one of the pedal linkages...

 

[lchris21]

the rear sub-frame bracket was trimmed a bit to allow the rear exhaust header a bit more room...........

got it off the build stand, first time in months, ready to fit the stand.

 

[lchris21]

got the side stand off some random bike from the scrappies, cut, welded, and mounted to the sub frame

Most of the major fab work is now complete, just a few hundred minor jobs left !!

 

[Habanero52]

Very talented!!! How are the screens held in place on the stacks, Snap in?

 

[lchris21]

thanks...

groove machined at the tip. the dish in the mesh keeps it in tension. I'll probably add a few drops of adhesive in there when the time comes just to make sure they don't rattle loose....

 

[ABCanuck]

This is looking great! Keep up the good work. I seem to have missed it reading through, Dan Moto exhaust?

 

[lchris21]

Good spot.....Dan moto silencer, but the rest is all me own work

 

[PaulBicker]

Very nice indeed!

 

[lchris21]

thanks.........still lots to do though :

 

[Narb1989]

this is just insane.
