Camshaft suggestions

I suggest to anyone looking at the 508/509 cam... the 484 cam will run right with it, come on earlier and only give up a little bit in the last 400-500 of rpm range.

If you drive around all the time at the top of the rpm band, like an old 125CC motocross bike, have at it with the 508. Otherwise run the 484.

Yep, sounding tough and running hard are lots of times mutually exclusive!
