just recently tore the engine down to a quad I got on trade. ran good but I wanted to tear it down and go though it this winter and make sure everything looked good for next riding season. only problem I have seen is that the roller on the rocker arm has a groove wore in it from the cam lobe. was wondering if anyone happened to have a rocker arm laying around from an old build they wouldn't mind parting with? just checking on here first before I go buy a new OEM part. thanks everyone and feel free to pm me or shoot me a txt @731-571-1835.
