1987 kx 250
Oblivious Maximus:
I have a Keihin PWM on my 87 and it works quite well. I was told it was from a late 90's Suzuki but I don't know that for sure.
Motopunk will have the information you need.

Another thing, If my motor was rebuilt 10 years ago then stored in the shed will the crank seals be perished? iv done maybe 25 hours on her and still fouling plugs every so often. It just doesnt seem to be running at 100 %
Hiawatha ride we put 14 hours on my mates bike so i must have done same and i went through 3 plugs..
Plug comes out oily and black sort of wet..
Since that long ride bike has not been happy, Tonight i read lots from here and something I read got me thinking, I pull off my "stator" cover the plastic one on left side, out comes the water :( im assuming the pressure cleaner got a bit close or the water spray from the back of my car may had something to do with it.
I pulled off "flywheel" not sure if im talking right as i said previously i can work on cars but doing 2 stroke bike for first time lol.. Now im sure those magnets on the inside shouldnt have rust on them?? what should i do im lost without the smell of 2 stroke it really hurts :(
i could get spark but im sure it used to be more spark and easy to start but not so easy any more ......

I will post pics of the magnets if that helps but its dark now down under and the lights are blown in the shed so have to wait till tomoz
looks alot older and rusty then the ones i see on you tube

Finally done, well as much done as it needs to be for me, Final touches are done and have a complete set of plastics now with OEM stickers, The bike is ridden almost daily so i not putting them on stickers are in pack i will keep them incase i sell the bike, New pegs landed, Showa forks from a Red bike, New brakes, tires, chain, sprockets, jets, the list goes on but finally DONE to my liking

The low jet will not come out have tried everything is their another carbie that will fit the 87 kx 250 or do i have to run that exact carb?? MIKUNI? is the one i have on bike but so many other things are different could also be wrong one.

to the carb..
i run at the moment the 39mm keihin pwk carb from a 1990 kx250. pilotjet 48, mainjet 175, needle n85c (stock in 88-91 kx250 ) airscrew 1,75 turns out... runs great ...
next upgrade for my bike is this one:
caught this fresh rebuild 88 kx500 motor for a real good price... :evil:
