Hey
I need help. I have a 2008 KX450F and having problems. The bike starts fine until it gets warm then it just shuts off. I have tried everything. I checked the kill switch, drained the carberated and cleaned it, airfilter is brand new, changed the plunger in the carbarator. I havent ridin for 4 weeks now I have workd at least 24 hours on it trying to figure out whats wrong. Can anyone help?

Thanks a lot.

What color is your plug? Maybe you have rich jetting...?

When cleaning the carb, make sure you are using carb cleaner and an air compressor to blow out each jet.

Have you tried a new plug?

OK been their done that on my KTM!

First check to see if your valves are set right, if there just a tiny bit tight when the motor gets warm you won't have a good seal on the cylinder & the motor won't start until it cools off.

If that doesn't fix it look at your ignition system, starting with the plug & plug cap! also check to see that your coil is grounded well with no rust.

You might even want to check the plug wire where it go's into the cap & see if the end of the wire is corroded. if it is just cut a tiny bit & put it back & you should be good to go!
