  1. Kaylee Runolfsson

    This head had some negative reviews. I disassembled the head after receiving it relapsed in the valves and lubricated the valve stems and reassembled did a check on each port to make sure there were no leaks, and everything was perfect. After installing the head compression went from 75 psi to 180 and the scooter started right back up.
