well there is nothing wrong with your raptor...i have a stock banshee with t-5's and a boost bottle and have out ran every raptor 700, raptor 660, and even outrun the yamaha 450 yfz or whatever it is...and it wasnt just in the rider cause i could outrun them from a roll or topend either 1...the 450 said his clutch was slippin so im not sure bout it but i am sure the banshee will beat a raptor
