gearing

RPM's go up, top speed goes down
better drive up off the corner, less pull into the next corner

what happens to rpm's when you go up on axle sprocket (add teeth) [wes]

the quick and simple answer would be, the rpm's would increase. But that alone would not necessarily mean you would be going faster. For instance; if you had a 15/60, (4.0 – 1) and your rpm was 6000, if you added one tooth to the axle, 15/61, (4.07-1) you would have to pick up 105 RPM to be going the same speed. You might accelerate out of the turns a little faster. It's possible that you might not pick up that extra rpm, in which case your peak miles per hour would be less.

Be aware that, with different gear ratios and a different peak RPM, that 105 RPM number could change. I have an Excel spreadsheet that figures this stuff out with no trouble at all. Tell me your gear ratio, and your peak RPM, and I'll give you better results.
