A few days ago i sent a message (not sure if it was recieved) concerning a 2000 model KLX 100 that my son has, problem is that it has no spark to the spark plug, the cdi and regulator checks out ok (tried both on a similar bike) There appears to be spark coming out of the flywheel magneto but there is no spark to the ignition coil while cranking it over, has anyone had a similar problem? tks.
