i have a 2002 kx250 and my suspension has been pretty terrible, i have aftermarket factory connection suspension. I have messed around with the clickers, rebound, spanner, etc. Just the other day i took a good look at the tag for the suspension and it said that the spring rate was 5.6kg. I did a little research and found that to be the proper weight for approximately a 260lb rider. . . . i weigh about 160 with gear 
So i was wondering what spring rate i would need, i was doing some conversions on this site: http://mx-tech.com/?id=home and found that according to them the correct rate for me would be around a 4.8 (i would rather set the suspension a little stiff since i am just 16 and still growing). what do you guys think about this rate? What should i do for the front forks?
Thanks,
Zach
