88 KX 250

Whats up you all, I am new to this forum because I am now a proud owner of an 88 kx 250, I originally bought it without a piston, I just put it in and it runs and the engine sounds really strong!

But I have a carb problem :| it has a keihin pwk 39 with a 162 main and a 58 pilot, the only way that it starts and runs is with the gold screw all the way in and the idle screw backed out pretty good and choke on and me blowing fuel into the reeds... then it will fire up idle pretty normal then about to stall, then I tap the throttle and it revs up real good and backs down to a normal idle for about 15 seconds until it wants to die again... anybody else run into some pain in the neck problems with the pwk?

thanks for any info, nice to be a part of the forum!

Welcome! cool bike you got there , i got the 89 kx250 . maybe you can post a pic of yours  :? and i also believe that it has a PWK 38mm unless someone upgraded it

concave3:
thanks! Ill post picks tomorrow! not to familiar with the difference between the 38 and 39 so i was taking a wild guess lol so I guess I have the 38.

1989kawasaki:
can you tell me if the front brake caliper has 1 or 2 pistons in it? you can tell by looking at it

concave3:
it doesn't work but it is a 2 piston, Ive tried bleeding it, I did it the same as the back but it fails to work! but yea its a 2 piston.
