KDXRIDER.NET

Hey guys,
Well, I'm picking up a KDX220 tonight (2001) because I want some variety from the ATVs I normally ride.
Basically the bike has IMS oversize tank, Prolite piston, minor porting, Procircuit reeds, FMF woods (Gnarly) pipe and FMF forestry approved silencer, gripper seat cover, MX rear fender, Protaper handlebars, suspension set up for a rider a bit lighter than me, rear shock revalved by Powerband Racing, skid plate, Barkbusters, radiator guards, pipe protector, new Dunlops. and original plastics/tank.

I am wondering a couple things:
How should I go about changing the suspension set up for someone heavier? Changing from a 185 to a 200 pound rider.
Also, has anyone else converted these to supermoto? I am planning on getting it street legalized and getting some 17" excel rims and lacing them to the stock hubs.
What gearing would you suggest for my street setup if I'd cruise at a speed of around 60mph, mainly 55 mph, 30 mph, and 45 mph roads where I live.

I want to have 2 different wheel setups/sprocket setups, one for trails, one for street.

Also, eventually when I go to do some mods, it seems like the biggest mod to do now would be an RB head mod? Then Carb?

Thanks!
Kyle

rb carb and head, yeah. Dunno how that's gonna go with your "minor porting" though. That throws a whole 'nother variable in the mix.

procircuit makes reeds? news to me.

Can't really recommend the KDX for a street machine. Being a small bore 2 stroke, they don't like sustained high RPM runs, nor the decel that follows. I'd say you'd be better off with a big bore 2t or a big 4t if that is your goal for the bike. KDX's belong in the woods.

Congrats on the purchase, and welcome to the forums!

Yeah, after riding it, it definitely is a woods machine, and a good one at that!
That means I need another new bike Oh no! Haha

Here are some pics, it has the stock plastic/tank too, but they have FOX stickers all over them.

You sure it has the woods pipe ??
Wrong choice for that bike

NICE!

Juliend.. what if you were ripping wide open on a regular dirt road for say....30 seconds...then let off...is that bad too? What is the "approved" way to let off on one of these after ripping at high RPM's for a bit?

It's true. A woods pipe wrecks a 220's power delivery. It needs a FMF desert or PC.

Bike looks great btw!

Yeah, I'm planning on getting a new pipe.

What is the "best" pipe.
I am big into quads (blah blah blah I'm a fag apparently haha) and as far as the 2-stroke lt250's and lt500s, there is one pipe that is the best, DrQ pipes, and everyone knows that. I am wondering if there is the same kind of thing for these?

Thanks guys

Also, K&N filter yay or nay, for all the atvs I've ever had that was the number 1 filter, and it seems like uni is the top for these? maybe I'm wrong, enlighten me :)

By the way, what are the best types of plugs for these?
Any significant differences noticed between brands?

I assume that the NGK BR8ES that the previous owner has in there is okay?

FMF desert (rev) seems to be the pipe of choice for the 220. Sometimes those Gnarly pipes come marked incorrectly. Inda can tell you at a glance if that's a woods or rev. I can't tell by looking. If you have the woods pipe, you might find a 200 owner who'd want to trade. The pipe looks in good shape in your pictures.

BR8ES is perfect. Nay on the K&N filter. Uni or Twin Air is good.

Thanks juliend, but I must ask, why not K&N? I just love the ability to wash them, and how they stay together great unlike the foam filters.

And the 220/200 use the same pipe?

I am big into quads (blah blah blah I'm a fag apparently haha)

Now that you bought a KDX you're no longer a f@g... more like bi. Just kidding. Super clean bike, you made a good choice.

With the IMS radiator shrouds I don't think you can tell at a glance if it's the woods or rev version. The rev nearly touches the stock shroud but I don't know how it looks with the IMS version. May have to look for a number on the pipe.

Woot! I'm still a closet atv rider though, haha. Don't quite trust riding a bike in the sand dunes after one of my dad's buddies broke his back and his hip last year in the dunes.

I think it's a woods pipe, seems like it's about 11 inches wide.

K$N can't handle the dirt. uni or twin. if you know how to clean them using the right product, they last a long time.

Right. The paper K&N filter element doesn't do nearly as good a job at catching dust and dirt as the oiled foam filter will.

Yes, 200/220 use the same pipe. At least, the pipe from one fits the other. Stock pipes are the same for 200/220. With the aftermarket pipes, because of the way they move the power around, work differently for each model.

Well, if it's the woods pipe - it should have some crazy low down torque.

Well i'm not so sure about that I have a mate who has done 7000 road miles on a KDX220 in two years and it still runs well. I have riden small bore two strokes for years on the road and have covered 1000's of miles and have yet to change a piston.

True, it can be done. It's just not the ideal machine for road work.

Yeah, thanks for all the responses guys.
I think I'll keep it as a trail bike, atleast for now, and pick up a bigger bore 4 stroke, or a cr500 or something for road.
I just love 2-smokers :)

Looks like a Rev to me!

That IMS tank throws it off....
