kx 250 troubles

[yog22]

I can't start my bike. It's a 2002 kawasaki kx 250. I can kick it all I want and it won't start. If I push start it it starts really quickly and once I got it going I can shut it off and start it again but if I let it sit overnight it won't start the next day without push starting it. If I pull of the plug it is really wet. What can I do to fix this?

Could be other issues as well, but it'll get you started. . .

Always go with the basics. When it won't start, check the spark and fuel. Go backwards from there. Nobody here is going to be able to help you until you give us more information. Do you have spark and fuel when it doesn't start?

 

[yog22]

I checked the spark and it has a strong spark, and yes it has fuel.

How about compression? How man y psi's of compression do you have, when's the last time you changed the top end? Do you have good spark, fuel on the plug indicates a flooding condition. Is the spark weak or strong?

 

[yog22]

i already checked the compression it is good. I changed the top end last august. The spark is very strong if I dry off the plug. Somehow while the bike is sitting it is getting gas on the plug.

Floats or float valve and read the jetting and plug reading threads.

What kinda plug are you using? If your using one of those NGK BREX plugs the electobe is so small the mildest wetness will keep it from firing as was the case with mine. At 12 bucks a pop you would think it would be a fail safe plug but no. I swtched to a regular BRES7 and have had the same plug in about 4 or 5 months now.

I am using a NGK BR8EIX plug, should I switch to one of the cheaper ones and should I go with a hotter plug?
