Default Re: Engine max went from 34mph to 25mph? wth?

had the same problem with mine... my brother riding my bike could do 45 mph (he weights about 80 lbs less than me) but he could only do 28-30mph after my engine started acting up.... I replaced the gasket not the head gasket but the one on the other end of the head that has fuel tunnels on it. Got some power back but the engine still acts funny, I believe I have a fresh air leak.
