I am having a hard time with my 2008 yz450f. The bike is very unstable almost everywhere. Through rocks the bike wanders and deflects, in whoops the bars are always twitching, and in fast single track with lots of turns the bike doesn't feel connected. I have tried everything that would seem to help. I have an RTT stabilizer, suspension done by one of the best in the business, and have checked and tightened my steering stem bearings repeatedly. The forks have been slid up in the clamps 8mm and the rear race sag is set around 110mm. I know Yamahas like race sag around 95-100mm but that would put even more weight on the front end, which leads me to think the problem would get even worse. I run 15psi front and rear. The front is a Dunlop 755 and the rear is a Maxxis IT. Any ideas to help fix this unstable, non-confidence inspiring feel?
