grom piston

  1. Grom Performance
    I just got the 125cc high comp kit. I'm about to install, but I didn't see any marking indicators for top, or bottom piston rings. Has anyone installed one of these kits and know what rings are top and bottom. Btw the kit came with a black and sliver ring. I know unknown shadow on youtube does...

    So we get a lot of inquires and emails regarding this combination. What works, with what, and how, and what will I get....etc. So we made a video to go over all of that information. Hope you enjoy: .
