If you purchase this kit, it is recommended that you also purchase a stainless steel valve kit.

The valves in this thing are weaker than the OEM exhaust valve is the GY6's Achilles heel. I've seen OEM stainless steel exhaust valves on occasion, but this is an exception. I bought this kit to repair the top of my engine that was wrecked due to a defective exhaust valve. The exhaust valve in this kit didn't last 300 miles before it burned out completely. At least it didn't break in the cylinder like last time. So if you buy this kit, you should seriously consider upgrading the valve.
