Hey Guys , You all know i recently built my bike and i just finished breaking her in not too long ago but funny thing is i never attempted a compression test . Due to the lack of riding i just noticed some weird noises coming out of my engine while a quick ride around my house. Performed a compression test and my gauge read 180 Psi ! Here's the deal , i do alot of trail's and i wanna try and keep my motor cooler . Since my head is cut and theres so much compression i think the motor would run hotter after reading in the forums. Im thinking about running b9es plugs and retarding my timing. I really think the weird noises were detonation from running 93 pump gas , So i think switching to race fuel will be the best bet. Does anyone here run Avgas?
