I was wondering if there was any good way to clean them up with out taking the engine apart. they don't need to be perfect, we just don't want to cause any more damage then good. This bike isn't going to be hopped up at all. most parts will be replaced with stock equipment. he just wants a beater that works, so he can become a better rider.
Untill hes within a few seocnds of the track record, a little carbon buildup wont matter
Run it, don't try and clean it, you just damage the valve stems and chew up the guides and seals.
