"The chambers will end up at 69 to 70 cc. With 10.5:1 compression or so, I figure this little motor will make really good torque down low, which is what I'm after. I still think the power will climb steadily up to 6,500, but with the smaller bore and the longer stroke, I'm hoping to make more grunt down low and have my curve start at a higher power level than the other builders. If I'm shooting for area under the curve, this is the best way I know to increase that area, beyond adding more cubic inches." View Related Article
