Works, cheap and quick
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.

It’s poorly made
The exhaust studs hole stripped After a day of running. And I didn’t even over tighten them.

Valves are leaking compression
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.
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.
