Hi, first of all im new to this board. I bought myself a M750 from a friend about 6 months ago. Fantastic bike, took me some time getting used to its temper and handling but im enjoying it very much now. The bike was standard, only mods ive done are termi slip-ons. They sound great but they dont increase the hp. Anyway i just love my bike, but how can i add a few hp without to much cost or trouble and can i put a 170 or 180 tire on my M750 without changing the swingarm?
