I have posted about my vulcan 2000 (power commander 3, vance &hines powershots, kn air filter, thunder air intake) back firing when I'm coming off the throttle, someone told me this was normal and the stock exsaust masks the sound so i wouldnt had heard it but it was there. I was telling a guy who build custom harleys about it, and he said it could damage the motor because it must be running lean, so which is the right answer? On another note this guy put larger pistons and cams on a fatboy, tuned and dynoed it, and it went from 85 hp stock to 100hp, almost as much hp as a stock v2K,LOL

  • Thanks Robert Vinson Cravey Jr., gonna have to look in the manual and locate that, not a wrenching type fellow so hope its pretty easy

  • He spent a lot more than $600, lol

  • The Rogue is like 110 bhp stock is that correct?, according to the guy that sold me my bike i get 130hp, im inclined to take his word on it since it does what i want it to do
