twizted269 Posted June 14, 2008 Report Posted June 14, 2008 is it possible for the engine to run but not fire right on one cylider if the stator is goin bad? everything but the lighting circuit ohms out within specs but i have repaired the coils. i know i could use a new one but just want to know if this could be causing the problem.

bansheerage Posted June 14, 2008 Report Posted June 14, 2008 are your plugs ok. even if you installed new ones still check them by removing one at a time and check for spark then swap them to see if the problem goes to the other cylinder. happened to me once. i was stumped for like 3 days. but yeah the stator can fuck up the firing on the cylinders.

No. Each time the coil fires, it fires both plugs. Unless you have a bad plug or wire, spark will be going to both cylinders. :geek: Quote

Like I said, Each time the coil fires it fires both plugs. This is a called a waste spark style ignition. :geek: The CDI has no idea that there are even two cylinders on the bike. All it sees is on crank position and the duration between seeing that crank position. :geek: Quote

FireHead Posted June 16, 2008 Report Posted June 16, 2008 so this would tell me that my problem cant be anything ignition related. i guess i need to work on the carbs some more or something. Unless you have a bad spark plug or spark plug wire, then yes it is not iginition related. :thumbsup: Quote
