... s**t happens... the 3. gear  of the ´87 is now for the scrabman ... same problem like on the ´83 kx250 2 years ago ...

need a good used tranny for the 87 ...  ... gears and forks are matching from ´83-´89  only the shafts were changed in 85 and 88 ...

or my alternative thought is to take my ´96 kx360-engine that i still have ...   much work again ...  :|

i have pics, but dont know, why i cant post them...   :x

today i made some bushings for the motor-bolts and the swing arm-bolt, cause the older engines use smaller diameter bolts ... 
and if the longer head-studs are in the mail, its time for making the rear-bolt on-headstay...  i haven´t found a 03-04 kx250-cylinder head, for this conversion...  :|

A posting was made last week that KXRiders is not going to allow any more direct posting of pics.
You will need to use a picture host such as www.photobucket.com or others.

Sorry...

Ya that sucks!  I noticed all my photo's for my thread were taken down!  Without photo's this site is not very user friendly.  I am the guy who did the 1987 kx 125 restore, if you have any questions about that 250 please ask, I ran into a lot of stuff regarding the 250 during my project.

that sucks realy... what is a build-thread without pics and why this complicated thing ?? i have no interest to post my pics on 1000 places on the web, only to get it here...
there is a easier way, for the whole side ,here has to be a pic-safe-programm that dont let copy the posted pics by anyone with the right mouse button...  my whole threads are now scrab, without the pics...   :x :x :x 

now back to the bike... the big cause for the engin-change is the blown 3.gear in the ´87 engine and to less time . i had also the option to put my kx500 engine in, but the 360 is much more rideable on the small racetracks here... 
i post the pics now on my website...  8-)

If you post the pics on your website, it is easy as eating Black Berry pie to put them here.


1. Go to your website and find the pic you want to post here.
2. "Right Click" one time on your pic. You will see a sub menu come up.
3. If you are using a Firefox browser Select "Copy Image Location"
If you are using Internet Explorer Select "Copy Shortcut"
4. Come back here and click on the "Insert Image" button and then past your link that you copied.

Now, go eat your pie  8-)

my work needs a pro- comment from you...   :-D 

i tried to use a keihin pe 38 roundslide carb of my ´83 kx250-partsbike,because i have 1000 keihin jets and needles but nothing for the mikunis, and theyre hard to find at the moment...
 now just ordered a cheap good used 39mm keihin pwk-carb that will work better ..  :-D
