I had the pin that keeps the ring from rotating on a wiseco come out and gouge my cylinder back in the day but have never had any problems in my current bikes.
Anyone know who that was that wadded it up in front of me? Looked nasty and scared the hell out of me. One broken leg a year on that jump is enough for me. Thanks for the photographic evidence of why I rode like a turd the first moto Rupe.
Raced Kenwortys plenty of times. One of the toughest races in my life was a mud race at Kenwortys but I'm not 20 years old anymore and don't enjoy riding in it or cleaning it up.
