Spring rates

[bigcr]

I just purchased an '03 CRF450 Honda and the manual says that
it's sprung for a 150-160lb rider. I weigh 215lbs. What rate springs
should I get for the forks and shock for my weight? I ride motocross
and sand dunes and I really can't afford a re-valve after dropping
six grand for the bike itself. Any advice is appreciated.

I very much doubt a 160lb rider would be correct for the springs-much nearer 200lb IMO.

With no revalving i would try a .49 fork spring and a 6.2 shock spring.
