I have a 2000 yzf426. I'k 6'4" and 300 lbs. I mostly mountain trail and desert ride. Like jumping and hillclimbing. Already adjusted the sag. I don't necessarily have a problem bottoming out just wondering if I should adjust the dampening and rebound?Seems pretty simple and would like to stiffen up a little if I can. Don't really want to replace the spring but if I do does anyone know the price range?
