86 Yamaha Moto 4 225
Hi guys. I have a 86 Yamaha Moto 4 225 that I am restoring. Got it running but it has a jerk when you start and stop , when you shift gears, and when you let off the gas. The backlash is in the transmission. The u joint and rear end are good. Do these have a problem with the transmission ?

Thank You. I have the clutch and the rear end out so I can check the free play in the drive line of the motor. When I put it in gear and hold the drive shaft, the clutch shaft, will rotate back and forth about 1/2". that is where the play is coming from. I took the side plate off the transmission and checked the backlash in all the drive gears,and they are all good. So I would say there is something in the bottom of the motor not right. It does not make any noise ,except for a Jump and a Clunk when I work the throttle.
