Have an OEM belt on the way, figure I should change it @1700 miles but through someones experience is it really neccesary for a $31 clutch puller? I am use to changing belts on snowmobiles so is it that bad to do it by hand on the brute? My biggest concern is if I will need to make any adjustments as far as the new belt being to loose. I know how the sensors can be. I got the big book but how hard is it too correct the proper tension?
