I just want to confirm about the adjustments of the rear suspension of an 04 YZ450 bike. Looking at the shock reservoir tank at the rear, there is a screw flat-blade style that clicks when turned. Is this screw for rebound damping? There is also a nut around this screw. Is this for compression damping? I have searched in the manual and it says nothing about which one to adjust. All it says how many clicks for adjustment at the last page of the manual. Last question is what is the standard set-up for the rear suspension, like how many clicks?
