I took the YZ450F to the mountains for the first time this weekend. I left my rebound front and rear at the factory setting, put the compression front and rear all the way to soft, ran 15 psi in the rear and 13 psi in the front tire. The rebound seemed good, the compression was good, but I seemed to deflect off of rocks a lot. Would running a little lower pressure in the front and rear help that, or put my rims in danger? What are guys that ride rocks a lot running for suspension setup and tire pressure? Your experiences can be a huge help for me. I definately know now that I need to get a flywheel weight. Only stalled it twice, but I got tired of always have to pull in the clutch while going down technical slow downhills.
