My gearbox was noisy is anything but 4th gear, and then in an unrelated event, on the return from a trip it would lock in first gear.
So, the bike came apart and and hasn't been looked at since. Until now, 10 years later.
Looking at the gears on the main and lay shafts, the fit is poor, there is major play and wobble of the gears on the shaft and looking at the gear teeth themselves, some are very worn with poor surface finish.
Being a grease filled gearbox I would expect a little play between the gears and the shaft but not as much as I have and I cant really do anything about the worn teeth.
So, really all I can do is put it back together and live with it. But - I am still curious to know how much 'wobble' there should be, if any.
