hey kurt do you all do stroker cranks??what would you suggest 2mm or 4mm for drag racing..that's all we do with our blaster..we run the 250 modified class sometimes,we are close to most 250's we need a little more top end. any suggestions appreciated>>

Actually Kurt sends them out to his machinist. I think at 4mm you start to mill away too much off the cases. A 3mm might be the right way to go. With a 3mm stroker and a 240 BB set up you'll be right at 250cc.

Actually, I donno why, but many Blaster drag racing engines we've done have prefered the 2mm. I run a 3mm for MX, and I've never built my own drag racing Blaster, but either a 2mm or a 3mm would be best for you.  |

I'm guessing that because a 2mm stroke revs up quicker. Just guessing but maybe it has something to do with bore to troke ratio.

Correct, saves the top end power to a point and revvs faster compared to a 3mm...YET, still gives you nice Raw torque.
