My cam plate on my Yamaha F8 broke while I was trying to shift it in gear. Funny thing is everything looks well greased from factory, however it somehow corroded enough to freeze slightly. Wear and tear did the rest. Fairly easy to replace. Remove the throttle handle. Remove the throttle rod. Remove the bolt holding gear handle. Remove the cam and carefully pop the C-ring. I re-greased everything I can see and sprayed corrosionX prior. Is there more that I'm not aware of????? Shifting still seems a little stiff.
