KX500 WOT ISSUES

cbxracer30:
Take the exhaust off and take the KIPS arm cover off, look up in the exhaust hole and pull out on the KIPS arm and watch to see if they open the whole way.CBX

BDI:
When a bike falls on it's face like that the first thing you should do is get out of the throttle and stop riding it. The second thing you should do is jet it up just incase it is to lean on the main. If the bike is to lean it will burn up and cost a ton of money. If it's not to lean you will know because the jet change will not help and you will know to look for somthing else. If you start looking at other things first and it was just to lean the chances are you are going to burn the bike up before you figure it out. If it is falling on it's face do to being to lean you should go up three jet sizes all at once. Then if that fixes it you need to figure out why it was to lean.

jforbesautotech:
I am going to have to check the kips valve again I think because when I got the cylinder back with the new sleeve the center valve would not go in right because it was hitting the sleeve. I thought I ground it enough so that it would work right but maybe I didnt compensate for the heating. If it is sticking at times could it be causing this problem or would I notice the power loss at all engine speeds?

BDI:
If it is your kips it will just go flat and stop pulling. If it is jetting it will fall on it's face and basicaly quit running.You can try everything else but if it is to lean it is going to cost you a motor if you don't try richening it up first.

BDI:
I guess I should add on this that if it is to lean that would indicate that you have another problem like a bad main seal (just for example) because it shouldn't be to lean with that jetting. If the bike has been modified extensively that would change things, my bike will fall on it's face with a 175 main.
