Here's the pedal shaft and claw collar that was in it on the last attempt. Also the final gear inside the case.
The clip on all there claw collars I have seems to be compressed pretty well. Maybe im not understanding what you meant.
Seems like when you pedal forwards the claw collar slides toward the final gear to pedal the bike. When you pedal backwards the claw slides towards the clutch cover engaging the chain attached to your countershaft and engaged the clutch.
So once you've started the bike, does the claw sit in a neutral position that keeps it from catching the chain gear that engages the clutch? Or does it go back to sitting pressed against the final gear?
Seems like if it got caught and was sticking to the chain gear thing that would maybe be what's causing the pedals to spin backwards and try to take my legs off when it starts.
I still don't quite understand why the last time it didn't do that at all but it wouldn't turn the back wheel either. Then after sitting idling for a minute, all of a sudden the the pedals catch and swing backwards again.
I've successfully rebuilt a few of these engines now and I've never seen this happen. Ironically, I've actually taken my time more with this build than any of the others and it's the only time I've seen this happen.
