I'm Having a problem

(1/2) > >>

gridlock:
I have an 86' KX500 and it won't start. I've had it running before and it ran fine, but now it won't start. I have checked the spark and it is fine. I have cleaned the carb but still nothing. It dosen't even act like it wants to start. I have replaced the reed valves. I have changed the plug. I just can't figure it out. I'm thinking it has something to do with the carb but I'm not sure.  Does anyone out there know what it might be?

    I would appreciate any help provided. I have been lurking on this site for over a year now and enjoy it a lot. I just don't have much to say about the 500 except that I like having it in my garage and I love taking it for a spin when I can.

mikesmith:
Maybe your rings are stuck or broke?New fuel?Is the plug wet after your attempts to start it?

machine:
Maybe you should try some "Quick Starting fluid"???

gridlock:
The bike kicks over like it allways did (just dosen't start) and I have put new fuel in it, and yes the plug is wet after trying to start it. But I do recall that when this first became a problem it was hard to get the piston to move so I squirted some WD40 in the plug hole and then it was fine.

Spider:
Check the flyweel key. You may still have spark just at the wrong time, but with your previous problem a compression tester is cheap a autozone.
