(1/4) > >>

kiwikx500:
Can a good earth be obtained by placing the spark plug on the aluminum head of the 5 hundie,i tried the other day and nothing then wrapped a piece of wire around the plug to the foot peg and nothing to,my bike has been misfiring and pretty sure problem is in the ht cap.Cheers  8-)

Do you have a service manual?? There are some test like ohming out the stator,primary,secondary sides of the coil.Have you removed your tank and checked for moisture in the connectors at the coil and at the cdi box? Clean those with contact cleaner. The plug cap screws onto the high tension lead. I found mine to be loose and you just twist it back on. Check for a loose stator plate.

KXcam22:
Touching the plug to the head anywhere should be enough ground to give you a respectible spark.  Most dirtbike ignitions put out a healthy spark.  Cam.

kiwikx500:
I do not have a service manual will try and track one down though,cheers guys for your good input and xtra tips,will be able to get it sorted alot eaiser now.Cheers  8-)

hughes:
If you have no spark at all at this time unplug the kill switch.
