SUSPENSION QUESTION
I have been doing some hare scrambles and trail ride whenever possible. I usually hit alot of hills with alot of different kinds of terrain both muddy and dry.
Right now I cant afford the kx fork conversion. I am 180lbs. How would I properly adjust my supension for my weight?

You need proper springs to get your frontend to work for you correctly. The stock springs are only good to about 135#

Your fine on the rear.... .38 to .40 springs would be just about right for you probably. You can get them ar Racetech.com.... about $100 I think...
The best springs are Honda Hot wound springs... you can order them from Servicehonda.com
Xr600 93-00 : .41
Xr600 85-92 : .42
Xr650L 93-02: .44
Xr400 00-02 : .40
Xr400 96-99 : .38
It’s the 1996-99 0.38kg/mm XR400 springs that are interchangeable and commonly used in 1995 to 2005 KDX200/220s

Just set the sag on the rear and adjust the compression and rebound clickers. Check out the suspension section on the site to learn how to do it...
You will notice an improved change to the forks... but not as much as a KX conversion. The KDX forks are just old technology....

my new to me 2005 220 has a silver coloured spring on the rear, and it is really soft. I can put the bike on a stand and lift the rear tire 3-4 inches by hand! The seller told me the bike is bone stock.
my 01 had a blue rear spring, and it was a lot stiffer, and the bike sat a lot (3"?) taller.
Is there a rear spring weight range chart by colour somewhere? Or should I just tighten down the spring and see how much it stiffens up?

Heckler-
I'd check and see where that adjusting collar is, first of all.
What you are describing does sound odd. Surely the wheel does not come up 3-4" without spring resistance when the bike is on a stand?
A shock with no gas pressure won't necessarily be soft. What will happen is that it will be really slow to rebound from a compressed state. Very strange ride, that's for sure.
To the OP-
The XR400 spring is a big improvement and so is a fork fluid change. There is lots of good information on here on getting the stock forks to work pretty well. A lot of folks find they are just fine with a spring change and a little tuning. Be carefull, you can make a career out of suspension tuning!

Wrong my friend - a shock that has lost the nitrogen charge will rebound back up like a rocket! I saw this happen on a KTM 200SX, you could push down on the seat and compress the shock normally, but let go and it would actually slam to the top!KarlP wrote:Heckler-

I was screwing around with shock pressure on one of my KDX's a couple of years ago and had a very different experience. At no pressure it would compress with no apparent damping and then hang up compressed and come up very slowly. I assumed the gas pressure was helping push the oil through the rebound valving......
Nearly threw me over the front riding around the yard!

Not so sure they are color coded or not.... but I think Race Tech has replacements. The stock is a 4.8 I think... a 5.0 or 5.2 should bring it up...
