Yup, a 70cc hi comp head from our friend benji. I ran it for a week and a half but had too much compression! Nice. $30 shipped.
Why is it too much compression ? Whats wrong with that?
predetonation with high octane and octane boost. I was using a very thin base and head gasket. I just switched to a factory hi compression head and solved that problem. Now, I sold my puch and dont need it.
