Default RE: OS 46AX On A Header & Pipe

Spinner, on a 2 stroke, it's the height of the ports that determines the timing. So if you widen the ports the timing is not affected, but if you raise the height the timing is affected. A common practice on many 2 strokes is to slightly raise the exhaust port for starters. What do you think Dar?

Thanks,

Ernie
