A 70/46-.46 will make use of the power much better, but you may get belt slip with the red/dk blue spring with it. If so go to the black/red spring. For max top end, you could keep stock gearing, but 25/41, 24/41, 25/42 will give better accelration.

you should not loose any top speed even with 24/41 . book says 100.xx at 8000 rpm at one to one. most polaris primarys will overdrive enough to see 110mph on gps
