Do you know what stock spring rate is on a 2010 yz450? Ive been told differnt things from .47 to .479 and trying to figure out what I need. Right now I'm getting a little midstroke harshness and not using about 3.5-4 inches average of my front forks even at 1 click from softest... of course this is for cross country and not mx. Im about 165 B ridder and am afraid to drop to too low of a spring rate and make it feel like mush... based on whatever the spring rate is im guessing I need to go about .2 less? Any thoughts would be appreciated!
