I lost a cylinder on my bike the other day, I have a low mile honda-matic top end to swap on to it and I know the cam is a much less agressive grind than the 5 speed cams. For cams I could put back my 1975 cam or I have a F2 motor thats frozen but the cam is nice (another low mile motor), I have heard the F2 was supposed to be a "hotter" engine. Anybody have any thoughts?
