Topic: excessive play in transmission?

[1981cb650c]

With the clutch removed, the input of the mainshaft (clutch spines, after the primary chain) turns 1/6-1/4 before the output of the countershaft (front sprocket) begins to turn. The transmission shifts correctly and is not noisy but I do notice it when switching from accel to decel. My spare engine is the same, is this normal? seems like an awful lot of play.

Yup, normal.  The gear engagement dogs engage into oval slots in the matching gears, if the slots were exactly the size of the dogs you'd never be able to engage the gears without grinding them.

This is a 750 transmission but you get the idea:
