You are making progress Les!

Tip of the day - remind yourself where the thrust washers go and don't forget to fit them - nothing worse than finishing a build just to find one at the bottom of a box - don't ask how I know that disbelief


 LOL..... mine was main bearing locating dowls on a CB360...

Bottom end back together now to wait for top end to be serviced so I can assemble 

Flywheel puller didn't arrive too lazy to take back axle out so bought a bolt that fitted the rear wheel nut biggrin Worked well 

Used Brian's guide and workshop manual looking good so far

Yamaha pistons are coming up as discontinued 

So ordering wosner  piston kit and Yamaha  top end gaskets 

Tomorrow through the bike shop will have to wait 2 weeks for delivery 

So will have plenty of time to check and service the rest of the bike

It all done and running like new only been round the block so far 

Checked the wosner piston 1mm oversize but 76 grams lighter  might help a bit 

Thanks Brian and the forum for getting me motivated to rebuild the ttr

Thanks 

I saved some time by making an early start today so I could measure and buy some valve shims as it is  Saturday had to get them before the shop closed at mid day  .

 Only bit on the bottom end  I really needed the manual to clarify is the correct orientation of the shift arms 

The top end was the usual but of fiddling to get the oil rings and inner ring on the piston properly had to resort to my glasses I've had for several years but never worn. The Yamaha grid for working out valve shims was easy once I got in and used it 

Overall not a difficult  job just stick to the sequence doing everything in order 

 

Will get it out for a return to the bush it's been raining for a few days we are still  drought declared

But should be a bit of mud in places earlier in 4th he day

Back from a ride nice and smooth and good power overall spot on

Changed the oil after yesterday's 15min ride a bit of glitter in the filter 

Just changed it again all nice and clean 

It's defiantly back runing well

I have updated my guide as you are right Les, the manual isn't that helpful. See here and go about 2/3rds the way down to see an extra photo and text on installing the shift works. Would that have helped you?

Brian

PS Remember Lin from Christchurch who kept a TTR with his brother in the Philippines? With his permission I have plagiarised some photos and text from his most excellent "DROWNED" thread smile

Spot on Brian 

Good description and photo 

Marking the top side for all three arms  when stripping down is a good move

Just relevant to my repair 

With mine I didn't mention when it went bang it also knocked a piece out of the shift barel so I was lucky I'd ordered the only full set of gearbox internals on eBay at the time so replaced shafts shift arms and barel all at once (new bearings as well as they are cheap )
