2002 KX250

<< < (2/2)

Hammer 4:
Yup, you'll definiytly need to respring it at both ends. For trail riding, you may, or may not want to smooth out the 2 stroke hit, i.e. make more tractable, you can add a flywheel weight 11, or 13oz would be best, also you can retard the timing about 4degrees (easy to do), and for more low end, you could add a Gnarly pipe. Oh, and keep an eye on the shock linkage, as the needle bearings need to be greased often, gas from the overflow washes it away. I routed my overflow tube away from that area.

I also have a 99 kx250 and love it.

hughes:
Thanks for the input. I missed out on this deal for the 02. I was second in line and first man bought it.

ericthewrench:
Wizzy,
Race Tech has a spring rate chart on their website www.racetech.com. On my '99 it looks like 5.4 is best for someone in the 230 - 240 lb. range.

azdirtrider75:
Team Green specs say to go with a heavier spring if you're over 185. With all my gear on I'm probably 220 and I'm running stock. Then again I don't MX. But I do ride hard and jump it. 250 2-strokes will have enough power for most riders.

KawiKid:
The 02 has plenty power for most riders I say go for It I run stock suspension and Im 6foot 68kgs I don't know how many pounds that is though?
