Check to see if the plug wire is threaded onto the plug boot all the way. It could be the CDI the can go bad on a whim. If you have to replace it, get one for the KLR250 dirtbike. Its about the same in price and will give a better spark timing curve

I'm not %100 sure but greg at www.cycleworksracing.net can tell you for sure. Just go to the CWR site and get the phone # and call him. He is the master of the Mojave world.
