The other day I was out on a hard packed RR bed and seen 99 on my speedo and my belt blew all to pieces. So the next day I bought a new belt and was out on the same trail except with about an inch of fresh powder and could only hit 94. I have 1 tooth ground off my speedo gear so it is more accurate than stock but still on the high side. Other Rx's that I know of can easily hit 110 on the GPS so why is mine so slow? I have an M10 from a Polaris which I read on here can rob some top speed but 15 MPH????? I'm running a 1" track with 192 studs, 23 top gear and a heel clicker secondary. It's hitting about 10,200RPM at the max. Also, I spin terribly out of the hole.....other sleds go by me like I'm standing still and it's a little embarrassing especially when it's a 600 lol. Help with tuning would be great.
 
Does griding a tooth off the gear mess with your odometer?
 
how are the bearings in the drivetrain? might have one coming apart.
