Oct 05, 2016· Just completed stage 5 on my 2015 Freewheeler. Went from 76 horsepower to 118 horsepower with 130 lbs of torque. A real nasty machine now. Pull the front wheels off the ground, guess I will have to mount some wheel extensions on back to keep it from going backwards and over. Put Vance/Hines headers with M/F extensions. Its got a real bad case of heart burn the way it sounds.
