Not had a lot of time recently but I did sort out the gear lever. It was very bent, something the seller failed to mention...but a lot of heat and a big ol' hammer sorted it.



Then a good clean up...



Got me wondering if the foot pegs would go onto an LC footrest so I got some large washers to give it a go



Then got one hell of a surprise...look what it says...



So yes, YZF footpegs will fit an LC footrest. Just need some extension bar for the gear change.

Peter popped round yesterday and quite a bit got done.



Gaskets getting annealed...



Knackered bearings out...



New ones in...



Some bits...he did leave some acid so the shocks will get a soak and see if that rust shifts!



And after some gearbox tweaks the engine is being rebuilt!

The shocks came out nicely, so I thought I'd get the coils off and have them powder coated





Slight snag as the coils won't come out! With the bottom part of the engine in I thought I'd do the clutch actuator, but surely this ain't right...



The rod goes all the way inside the engine without hitting anything on the other side.



Hmm. So after that minor setback I thought I'd have a test run with the twin shock set up.





I like that.  And it's not far off where the mounting lugs need to be welded to the swing arm. Just awaiting some gaskets and spacers now and I can crack on!

I assume you have the part diagrams to determine what is missing from the clutch mechanism

Yes, would be good learning exercise for Alex to figure it out for himself , so no hints like ‘what did you do with the clutch mushroom Alex ?’
 Ok ?

I knew you would find the part diagram useful

Right. New sit rep.

Dusty popped over today and he torqued the clutch nut in place. Then explained that the plates have to go on in a clockwise fashion...and then suggested the friction plates should be soaked in transoil first so they are! Thanks mate, your help is invaluable.

And whilst we discussed both the Popsicle and this bike he noticed that the shock mounts on the frame had been welded up! I had been using the holes where the subframe bolts onto. Ooops. This opened up a fresh discussion and I may just get this mono shocked instead. I have a YPVS shock so that can be used. It may well be cheaper than opting for twin shocks too. So when some front wheel spacers arrive I'll get everything level (chain run etc) and see exactly what needs chopping off, aligning, drilling, welding and probably swearing at.

Cheers Peter, Tony, Dusty and everyone who's voiced an opinion/idea/thought or whimsy as it's all been great advice!

Indeed not and it can be a pain in the butt, butt  ;D

So. Clutch plates back in, correctly this time. Hooked up the cable. Hot damn I have a working clutch!





I do need the 3 long thin bolts that hold the stator on, anyone got some?

Gaskets and that engine mount turned up today so first off, fit the mount. Then the barrels...





They went on quite easily, piston rings and me don't normally work well. Heads went on next...





Then the carbs. Some folk say LC inlet rubbers won't fit an RD some say the opposite. Well, they DO fit!



The wheel spacers are en route so next step is get that front end done and size everything up.

The wheel spacers arrived today. Custom made for the Mito forks and stunning to look at. So they got squeezed in...



Then the wheel went on





Next I wanted to get the chain clearance right. Using the perennially popular CAD method (pun intended) there seems enough room now. I can easily adjust things later on. Then the second exhaust got a quick clean...



And I had a trial fit. Got an idea of how to mount these without having to resort to welded on brackets.



And the kill switch is on!



If I get some time tomorrow I'll test my mounting theory...notice I said 'theory'... :D

Using a bit of MDF I knocked this up.







If I replicate that in some ally, perhaps with holes in it for extra lightness, and have it angled at the top so it moulds around the frame...it might work. Best I can think of at the moment. The foot rests have no proviso for an exhaust to mount onto...Any thoughts?
