Chandler... you are right. The Sheeve only got me just 4 MPH, but read on
I called Dave at ABS Wholesale (see the link above) he gave me a brief rundown on the Stage 3 package and told me how to remove the stock sheeve. 20 minutes later it was off. He graciously met me half way between Florence and Queen Creek. He had all the parts with him and was on time. I gave him the cash and my sheeve. Within an hour (including a 30 minute drive) the new KMS sheeve was on. I must say I was surprised to only gain 4 MPH. I expected more, it did seem to have better acceleration at the low end. BUT I then put in the Dynatek CDI, WOW! I noticed instant gains in throttle responce and smothness, just backing out of the gaurage. I took it down the road and easily hit 55. It had more, but it was dark and I got scared as my daughter was with me. The shity stock head lights are not worthy of that speed. I have yet to re-jet or add the air cleaner and exaust tip. Regardless of performance gains that might yet bring I'm happy!
My Rhino would do 42 stock, but prefered 41. This was an easy, honest 15MPH improvement. But it's not just the speed, it's the smoothness an quicker reving that I like.
I would recoment ABS to anyone for thier service and the simple package deal.
