Amazed that I was able to rebuild the upper section of my scooter for total of 68$. This comes with new valves n guides already assembled so no messing around w lapping valves, grinding seats, spring compressors, etc.

I have purchased many gy6 cylinder heads but this is got to be the worst one. Intake valve is not closing in completely so all compression is lost.

Good product for a small price. I love goofit because I can order quickly and cheaply with same-day delivery but the lack of quality control angers me. One valve was poorly protected.
