looking for parts help

Recommended Posts

Ok so a long time ago when I was in high school I picked up a 82-83 KDX 250 and then I made a deal and gave it to my uncle. he's wanting to get it going again but the chain had jumped off and blew a big hole in the case. At the time we tried JB welding it haha that didn't work my uncle bought a set of cases for it (at the time we believed it to be an 82) and the 82 cases he bought didn't match up, different cylinder mounting. Now he isn't wanting to buy another set without being sure that it is right. At the moment I have the number off of the cases: DX250AE004476 I'll have him forward the vin on the frame to me so you can get a better idea of what we are dealing with. We aren't sure if the bike has been pieced together or if it is all original. Where can I find info on this engine?

Why?? It's a KDX!!

I'm not sure on the engine number, but will see what I can find. Hopefully KDXGarage will see this, I bet he knows! With the frame no we could definitly get a year, but that doesn't mean the engine wasn't replaced at some point.....

Are you sure the engine number doesn't start with a K?

The first letter after the marketing name (KX125, KDX200, etc.) should be the model. So judging by that number the cases are a KDX250-A. I looked on Kaw fiche and the KDX250 A model was only 1980.

For models that use multiple years like B, I think the only way to tell the cases apart is by what range the number falls into. For instance, KDX250-B1 say they made 2500 cases, so if the case number was higher than 2500 then it's a B2 (or higher). The dealership should be able to tell you what range the case numbers were for a particular year. The case number 'should' also match the vin. My 94 KX250 was #400 so my VIN and case are both "400".

Model (9):

KDX250-A1 (KDX250) (1980)

KDX250-B1 (KDX250) (1981)

KDX250-B2 (KDX250) (1982)

KDX250-B3 (KDX250) (1983)

KDX250-B4 (KDX250) (1984)

KDX250-D1 (KDX250) (1991)

KDX250-D2 (KDX250) (1992)

KDX250-D3 (KDX250) (1993)

KDX250-D4 (KDX250) (1994)

Also, if you look on your cylinder for a 4 digit number cast into it that might tell us the part number, which in turn you can find the year.

Like this:

Oh, one more thing. If your bike is in fact a 1980, the match for your cases is a 1980 KDX250 or 80/81 KX250.

Look for the cross reference thread I made in the FAQ sticky.

Well the frame had a kdx seat on it. I'm not sure what is original on it for sure lol I'll get a frame number but my uncle said that is the engine identifying number.

I'm not familliar with those bikes, that's why I asked about the K. Kawi might have left it off and just used "DX" as an identifier and to keep the amount of characters the same.

1982 engine numbers start with DX250AE004801, so that is 1981.

The frame number given later is 1981.

Remember that 1980 had twin shocks in the rear.

Good luck with it.

lol I'm not a Kawasaki guy so I wouldn't remember. :confused: It was honda for me until I found out honda couldn't make a decent four stroke. owned a 2004 450 that went through valves like I go through candy. So I went to yamaha and I've enjoyed it so far :thumbsup:

      I have a problem with my stage 2 exhaust cam on my rmz whenever I kick it over the exhaust cam likes to stop at the lift unless I put it at tdc or kick it really slow it runs fine when it starts and I have played around with the shims right now all the valves are shimed and I have checked the timing everything’s to spec it just gets stuck at the exhuast I’m pretty sure it’s something to do with too much compression I probally will end upbuying stock cams but wanted to see if anyone knows how to fix this first

      I recently acquired a 1990 KDX200. The bike runs reasonably well for it's age. The first ride over 30 min the gearbox oil started overflowing into the airbox (overflow hose is routed to airbox). The oil that overflowed and the oil in the gearbox are an odd shade of dark forest green. The oil appeared to be overfilled slightly which explains the overflow. What I don't understand is the weird dark blueish greenish gray color of the oil.  I believe the PO used motul 10w40 ester gearbox oil because he gave me a half used gallon. I use Motul 710 2t oil which is blue, and run green coolant in the radiator. I drained the gearbox oil and there was a nice little clump of dark gray metalic paste on the magnetic drain plug, which should explain the gray hue. What I do not understand is the greenish blue hue. Anyone know what in the heck is going on with this old horse?
      The pic shows a sample of my drained oil. When held up to the light it turns more of a green color. Oil still feels slick as can be.

      will a clutch basket from a 98kx250 fit a 96kx250? How about the carb also?

      I have a new cylinder that i bought to rebuild my 1993 kawasaki kx250 with, because the old cylinder was destroyed. The guy said the cylinder is overbored a little but never gave us numbers. The new one i bought came with a piston thats been used and i would like to replace. I believe the piston that came with the cylinder is the correct size, but it very well could be off and i have no way of knowing. So how do i properly measure the cylinder bore, and how do i use this measurement to find what size piston I need to get?
       
      thanks,
      Kaelan
