  1. 1974 TY250 piston arrow / window direction

    Thanks guys. Follow the arrow and not the holes. I usually only have holes in my pistons after I ride it.

  3. 1974 TY250 piston arrow / window direction

    Dirtclods posted a topic in Yamaha
    I have ran across a discrepancy in what I have and what I have read and seen. I have a stock and aftermarket stock size pistons. Both have the windows on one side and the arrow on the other. The parts diagrams I have looked at all show the arrow and windows on same side facing forward toward exhaust. Am I missing something or is something not right here. I am about to put the piston in with windows toward exhaust but the arrow will face back which goes against every piston I've ever installed.
