Can you explain or show difference between the 4 & 5 speed mechanisms, may explain why I have issues with overshooting 2nd gear on my 380 when downshifting

Pete

A 13t or 14t should be all you need for a 250cc 5 speed  spot on Tony







SHAFTS




BTW this is the difference between a 4 and 5 speed shaft. 5 top 4 lower.The stop plate is 2mm wider on a 4 and theyre welded to the shaft. And the quadrant arm of the 4 has 3 notches, the 5 has 4


To replace the shaft means spliting the cases

Cheers

Shortshifter, thanks for the heads up. the spline is a bit twisted as well. Better to do it right the first time I reckon. Chasing one down
