| Re: Crf150 dropping down to a 125cc I'm sure it's possible. You might have valve to bore issues needing a little sleeve notch, but maybe not. |

| Re: Crf150 dropping down to a 125cc The valve pockets on the piston are already at the edge of the piston. The stroke would have to go down to 36.5. This would send the peak Hp in to valve problem range. It would also be very hard to compete with the 90cc two strokes at atva. You could leave it at 150 and run supermini at the WPSA nats. S.C.R. |
