ok well i'm not going to be racing in a league because in my area there is no such thing unless i drive for about 4 hours and i can't see myself doing that anytime soon.

So tell me about grinding the crankshaft... what would that do to the performance? The opening on the crankshaft that you can see under the carb? do you port that out?

I would appreciate if you could explain this to me.. I'm an engine fanatic and love to experiment..

Thank You
