Gear box 1972
With motor turned off it shifts easily. Start the bike up and it requires more effort to shift. more effort than normal. Also, it is reluctant to shift into first with out some grinding. This seems to be a reoccurring theme lately when I put a gearbox back together. Primary and rear chains are adjusted properly. I replaced the mainshaft in this one because of a bend. I put in a good used one. The shifting into first improved slightly. All other bushings and bearings have been replaced except for the camplate spindle bush and the gearchange quadrant bush because those two require removing the gearbox. They appeared to have no excessive movement so I left them alone.
The shifter shaft has been shimmed but still has .020 movement. What am I missing?
Once under way all shifting is good and positive but requires more foot pressure than normal. When hot it shifts a little easier into first but it has to be carefully done.
