1998 kx250 engine case compatability?? Need help
« on: April 28, 2013, 12:37:55 PM »
Hey guys, i need a right side engine case for my kx250 that was made 12/97. The engine code is kx250ke026136.... Apparently the part number says the 98-99 cases are the same but i was also told that only 94-98 kx250KE Cases will work and according to my research the 99 is the kx250LE series.... So 94-98 are kx250K series and the 99 on is the kx250L SERIES....so is that right or are the 98-99 cases actually compatible?!

Hello bigdaddy00.
Welcome to the site.
If you check the parts numbers for the cases you will see that 98-99 are the same.
Yes 98 uses KE and the 99 uses LE for the engine ID.
I believe that you can use back to 94 on your 98 but there are other members here that have tried it so be patient as it may take a day or two for everyone to get back from the weekend.
You'll find a lot of good help on this site.
Post some pics of your bike and your riding area's as we all like to see what others are up too.
You'll find this site way more useful then the other site you posted your question at  :-o
The four stroke engine: That's one stroke for producing power and three for wearing the engine out.

you can use 97- 2004 engine-cases.
 optical the cases are the same 92-2004. but the devil sits inside  :evil:  
92-96 are another shift forks with smaller diameter to the rods. in 97 came bigger rods .. also were the clutch cover a little bit diferent. if you look good at yours, you will find at the bottom a closed hole on the main-cover and  a longer bolt goes through both parts of the clutch cover. thats the update in 97.  :-)
on 92-93 is JE stamped in , which means j for the frame 92-93 E = engine and the continuous production number , than k-94-98, L 99-02 and so on.. :-)

 here is a pic of my 97 clutch cover . you see the closed hole? in 96 sat there another bolt  :-)

I have a right side case half in good shape if you are interested. Posted here among other parts: http://www.kxriders.com/forums/index.php/topic,11499.0.html

Throw me an offer if you need any of this stuff. I'll get the engine number and post it up.
It's hard to keep a drivers license riding a 2 stroke dirt bike on the street.  If you drive within the law they are VERY boring.
