Hi a friend of mine just bought a used 2003 CR125 with an fmf pipe and v force reeds with 12 hours of riding on it.
When he got it home and rode the bike we can hear this loud knocking sound from the engine especailly at higher rpms the bike doesn't seem like it is running lean but he did buy the bike up north what do you guys think it could be jetting or a engine rebuild! Did the dealer rip him off?
