    Hello, Got a 2007 raptor 700 SE for my little bro with a new Yoshi slip on, K & N air filter and a HMF power commander (which I dont think works correctly because on startup and in idle white smoke comes when you give let off the throttle and idles seem to slow down). Long story short he does...
