Im having some trouble with my suspension. It hasnt been sent out for my weight and that might be the problem but here it is. When going down a fast strait (4th-5th gear) then slowing down right before the jump to not over shoot i get a pretty good amount of head shake. Also in ruts or anything else with a big sqare edge in it feels like my bike doesnt soak it up at at, it hits HARD. Any suggestions?
