Apparently when the magnet rotor catastrophically failed, it bent my output shaft. I suppose it's not that surprising considering the carnage I witnesses after opening the primary case, including the fact that the output shaft was a bit mangled so I had to sand it down before I could even slide on the new rotor. After putting it all together I checked the gap between the rotor and stator and it is tight on one side. I rotate the engine and it's tight somewhere else. Doesn't seem to be rubbing though. So not bent horribly out of whack, but bent nonetheless. I'd like to get a performance crank and throw in some new cams while I'm at it, but don't have the cash at the moment. So I guess I'll risk riding it for a while... Bad idea?
