KX500 AF Running like a 200
Goat:
Those dents seem to be a bit overkill. It should still run better than described though. I'm not sure if you can get just the pipe or not but Service Honda was building pipes for the aluminum frames at one time.
RKPerformance:
Frame is a 2000 KX250
Pipe is a FMF Fatty
No idea who did the conversion, but the welds and overall conversion look minty

Rotating the arm all 3 valves appear to move and close as they are supposed to. I noticed a little coolant in that rubber elbow that houses the rod lever. No idea why there would be a little coolant in there?? Piston looked really good as did cylinder. One thing troubling to me was the pipe. It is a FMF Fatty pipe and whoever did this conversion really rammed this pipe in there. The neck bend coming off the cylinder is pinched very very tight. I dont know hoe it can breathe. Also near the end of the main expansion chamber the pipe is smashed waay in for clearance issues. Im starting to think this pipe is a major restricting point on the bike. The frame is a 2000 kx250AF. DOnt know who did the conversion either so i dont know what kind of pipe i can use to try and see if another pipe is better>>>?

I'm pretty sure they didn't make aluminum frames in 2000... Did you buy this bike from the ktm dealer in medford oregon?
motopunk:
first kx-f aluminium frames were build in 2007 .
i think only your engine is a 2000 . :wink:
i also think you should buy the stock needle for the kx500E-models and take the dents out of this pipe,as much as possible. check the crank seals, base gasket and reed insert for air leaks.
thats the only way to solve that problem... 8-)
