    Awesome riding day here. So, want to as you a question on 66cc Skyhawk Slant. I went out today for about 10 miles. Everything is going fantastic. I opened it up right at full throttle, and it 4/stroked 30mph +.... Wonder why? Other than after 30, it was wonderful.

    I'm using once again NGK B6HS, with very good tan color?
