Default New guy with a kdx

Just got a KDX200 for free from my cousin. Needs sprockets, no biggy, carb needs a rebuild, leaks gas out of the overflow or pressure relief valve or whatever it is, no biggy. Anywho.... Are parts interchangeable from a KX of the same gen or different gens?

Sounds like there's crud stuck in the float. Probably the pilot jet is plugged - make certain you can see daylight through that jet before putting the carb back-together. Wear eye protection (that carb shyte HURTS!) and avoid spraying/soaking any soft, rubbery parts in the carb cleaner - it causes them to swell and stretch.

Most parts are interchangeable within the "generations" of KDX's. They changed slowly until discontinued.

Superb trail bikes, they were. Can't beat the price.

Another question. I want to do a full exhaust for this too, but all I can find is the pipe but no silencers. I cant find any that will fit my specific bike but will one from a later model 200 work?

You can usually find one at an accessory shop that will fit if you fabricate a bracket. Just have some mercy on your neighbors with the noise level.

I don't remember which one, but there is an aftermarket silencer with removable plates. You can tune how much noise you want by removing and adding plates. One of the more dedicated off-roaders here might remember which one it is. There should be one to fit your headpipe.

That's a Supertrapp. Not good for two-stroke dirtbikes.

Yours is about an '86-88. Aircooled, and 1 disc brake. I doubt anyone is still making aftermarket silencers for it. Hmm. I see FMF still has the pipe, but no silencer. You will have to adapt a newer model to it, or find one on ebay.

I looked on ebay and all they have is the FMF pipe. And yes it is an 88. Making an adapter for a newer one is not a problem as I am a machinist. Should I be all set with a silencer that is made for a 200 but not my year?

Gearing question too. I dont really know what changing the tooth numbers do? Im pretty sure it has 14 in the front and 49 in the back, and while looking up new sprockets because i need them, what would it do if I went up or down in teeth? Never really knew what it did.
