The transmision on my '74,850 does not seem as smooth as memory tells me it should be,upshifts are ok,gears drop right in,downshift with a "blip" of the throttle and the gear does not drop in until the clutch is fully engaged,downshift WITHOUT "blipping" and the gear drops in ok .. low speed at this point!, anyone got a clue as to why?, the clutch adj. is one full turn of the screw out from the pushrod,primary and main chains are adjusted ( slightly loose if anything).I may pull the "box" over the winter anyway but a clue as to where a problem may be developing would be appreciated. Ride safely. James.
 
One full turn is a bit much for a clutch that's all broke in. Try a half turn your looseing some lift.
 
Sounds like there might be too little end play in the layshaft but I am not sure why this would change much over time. When I rebuilt my gearbox, I shimmed up the layshaft a bit too much and it is sometimes hard to get it into first gear. Shifitng gets easier as the transmission warms up. I've only ridden the bike about 50 miles since the rebuild so we'll see if shifting gets any easier over time. What I have read is that if you have too much end play, shifting will be sloppy and the bike can pop out of gear and if you have too little, it is difficult to move between gears.
