What makes this thing work so good in the woods apperently is what's holding it back on the ice, and I bought it mainly to race the ice endurance races, it runs great but there has to be more power hidding in there.
We tried an 13' 450SX muffler with a 52t rear and that helped little, I did check the ECU part numbers on a 13' 450sxf and there the same, this weekend I was thinking may trying to plug in the sx ECU, a dealer sudjested the "european map" but I thought that was a fix for the 500EXC & XCW locked ECU's.
Love the bike, just need to get it up to speed for the ice, and then put back to stock for the summer.
