I had a Rickman 125 with the Zundapp 2 stroke single. When I got it it wouldn't run. I sorted that out and it ran strong but, You picked a gear and stayed in it because it would not shift.
There was a locater peg that had been busted out of the cases that was supposed to prevent the shifting ratchet from rotating.I tried J.B. weld and it lasted for about two shifts.
The thing is when you had it in first it would pull the front wheel just rolling the throttle.
I sold it and got my money back but now wish I still had it.
