I have heard somwhere that if you swap out the 800 H.O. air box for a 800R air box you yeild and extra 2-3hp. I have looked at both and the 800R airbox has a larger diameter intake than the 800 H.O. airbox. That being said, do I have to change my clutching to compensate for an extra 3 H.P. or set my TRA clickers down a notch or two??
