Just to give you the update on this
Since last post I ordered few parts:
- shift drum stopper, neutral stopper and stopper cam plate replaced by new ones
- new clutch springs
- basket filed
- basket play adjusted (thanks to Oddjob's shim set!)
- assembled, new oil, filter etc
I did not do anything with dampers in clutch basket - I'll keep that for later (winter job, highly likely engine to be opened anyway for primary chain replacement at least)
First ride : up-shifting issue is still there, but I feel it less happening / reduced.
When testing shifting mechanism before assembly clutch and cover (with new replaced parts) I did this video to show the issue that I feel during shifting - when up-shifting, I usually cannot change gear unless I turn gearbox. Down-shift is always w/o issue. It is clearly visible in the video that when up-shifting, movement of gear drum is "stuck" in the midway and moves more when I turn gear (clutch basket shaft). This is exactly what I'm referring as my up-shifting issue.
