If you are a full on racer (wide open racer) look into the big bore packages(416 405 390 etc.). If you are a recreation rider look at the 330 and just bore it out .080. Just what ever suits your riding the most. Just take it one step at a time if you are in need of money or if you have already saved up get the kit-and-kaboodle(carb cam port polish etc.)

92-250X, I think your mistaken with your 1.00 figure. That's an inch! I think you meant .100", either way I'm not sure how many cc's that would give a 250X.

exrider02, .080" over is 297cc's for sure.
