My first post on Thumpertalk. I just bought a new 2006 YZ450, I've put about 8 hours on it now and got the jetting sorted out. My question is about suspension. I weigh 145 and am a Vet Beginner. The suspension is really stiff for my weight. According to Race-Tech I should go down to a .44 spring for the front and a 5.2 on the back. If I just buy the springs will the valving be ok with just adjustments or should I have the whole suspension redone by someone? Any suggestions will be appreciated!
