[QUOTE="Shaw520, post: 112967, member: 18459"] Guys, having some experience with getting these bikes to make power, IMO the big bore kits will yeild the best HP to dollar ratio, [i]without[/i] taxing the valve train, and [i]without[/i] exceeding the normal rpm range. And, in the same price range. Changing the cam, and rpm range will put a limit on reliabilty and longevity. Also,..with the bore kit, the only real necessary item to go along with it would be a pipe and silencer. After that,...a pumper carb and polished ports only make it better! [/QUOTE]
