I have a 2000 YZF 426. Suspesion is stock(I beleive). I'm 6'3" 290 lbs. I really don't bottom out much but I do notice a lot of sag. Not a track rider but I do like to jump a lot. I'm thinking I need to adjust the suspension. Any suggestions? Oh by the way, the two guys I ride with have '06 KTM's 525's and i have climbed stuff they could'nt and pulled away on trails.
