I have a stock 05 rmk 700. I put 480 jets in and set the needles in the middle position, to be able to ride in the midwest. Yesterday was the first real day i could go riding but we noticed that my sled will only top out at 45mph. Everyone wanted to ride it to see if I was messing with them or not. I rode my buddies sled and the only difference is he has a can and pipe, but his hangs the skis like crazy. What adjustments should I make.
