I have a CR250 that had been modified with the Eric Gorr 265 big bore kit. Yesterday I competed in an extremely muddy hairscramble event and almost didn’t finish due to the bike overheating. I’ve never had this happen before and assume it’s bc of the very muddy conditions, getting the bike stuck and having to rev it out. Symptoms the bike had was boiling over through the radiator overflow (I use engine ice also), bike losing bottom end power, and engine rattling/ticking. I have another race coming up in two weeks and plan on tearing the bike down and replacing the piston/rings. Is there anything else I should check/replace that could have been effected by my engine overheating like that? Any reason to split cases and dig into the bottom end?
