I have been looking through the forums for advice on setting up my 07 YZ450F suspension. It seems that riders commonly run the forks 5mm with 95mm of sag. I have tried these settings but ended up with serious head shake. My current sag is 105mm and the forks are even with the top of the clamp. These settings seem "OK", I don't receive much head shake, and corners are tolerable but not great. My question is, why am I having such a hard time dialing this suspension in? Are 07 YZ450's tough to tune? My previous bikes were 100mm sag, a couple clicker tweeks, and RACE! Also, I am 165 lbs and ride 35+/450C and (to my knowledge) the suspension is stock.
