Re: sprocket wobble
after I last got my 41 chain on, the sprocket was still wanting to let the chain off. I walked up and down my driveway with the clutch in and each time the chain wanted to jump off the sprocket, I tapped the sprocket with a hammer. I kept doing that until it no longer was trying to come off the sprocket, I rode a bit with out the motor and it stayed on fine so I fired it up and it hasn't been a problem since.
