Lately my scrambler feels like it takes a lot of rpms to get moving from a dead stop, especially in reverse. I have to idle it to about 2500 rpms to get it going and once it does it almost jumps into the gear, its not smooth at all. It just started doing this after i had a new belt installed. First few days it was fine but now after about a good 40 mile ride with some aggressive riding it seems like something is wrong. Any ideas? Also i did break in the new belt how they described me to do so.
