renlt250r Posted October 17, 2006 Report Share Posted October 17, 2006 I just purchased a Banshee for a reasonable price because the guy could'nt get spark. So I figured , No problem!......I've been working at it for a while and I'm frustrated. It has a new stator, and the coil is supposedly new. I've cleaned up the flywheel and there is voltage going to the coil. After checking the voltage to the coil and plugging it back in, I get one spark and thats it. Any help would be graetly appreciated. I can give more details if needed. Thanks Quote Link to comment Share on other sites More sharing options...
Hollister_Hitman Posted October 17, 2006 Report Share Posted October 17, 2006 Does it still have the t.o.r.s? Quote Link to comment Share on other sites More sharing options...
renlt250r Posted October 17, 2006 Author Report Share Posted October 17, 2006 Does it still have the t.o.r.s? No, It has aftermarket Keihin's. Quote Link to comment Share on other sites More sharing options...
renlt250r Posted October 17, 2006 Author Report Share Posted October 17, 2006 How much voltage should be going into the coils? Quote Link to comment Share on other sites More sharing options...
Screaming Yellow Zonker Posted October 17, 2006 Report Share Posted October 17, 2006 have you checked all the wires for bad spots and burns? I would also check your switches making there is no short in those. What I have done before to check for power out of the stator is take a 17mm head bolt and insert it into a deep well socket where the threaded portion go through the square hole and chuck it into a 1/2 in drill and spin the engine over with no spark plugs. then take your volt meter or test light and check it out. (this is where 2 people might be necessary) you also might want to drip a little oil in the cylinders to prevent a cold sieze. if you have plenty of power than it might be CDI failure :sad: ... Good luck. Quote Link to comment Share on other sites More sharing options...
akita8 Posted October 18, 2006 Report Share Posted October 18, 2006 (edited) Do a resistence check on the stator and if thats good do a resistence check on the coil, kill switch and ignition switch. Visually check the wires or if you are feeling ambitious do a continuity check on the wires (remember to check the continuity from end to end and also to ground). Make sure plugs are good. If all the checks are good it's the CDI that's bad. Ricky Stator has them for a resonable price. Edited October 18, 2006 by akita8 Quote Link to comment Share on other sites More sharing options...

renlt250r Posted October 19, 2006 Author Report Share Posted October 19, 2006 I've checked the stator, and the resistance is within spec. I just bought a new coil and have tried 2 different cdi's. I've also followed all of the wires looking for breaks. What it is doing now is: If you unplug the wires from the coil, and crank the engine over for a few seconds...when you put the wires back on the coil and turn it over, you get one spark, but thats it. The only thing tat I can think of is that the flywheel is a little rough looking. The guy I bought it off of must have used a large screwdriver to pull it off. Any advice would be appreciated. thanks Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted October 20, 2006 Report Share Posted October 20, 2006 How about the trigger or pickup coil? Quote Link to comment Share on other sites More sharing options...
jmiller696 Posted November 6, 2006 Report Share Posted November 6, 2006 I would second on checking the wires. I had the same problem after installing a new stator. found a wire next to the cdi was cracked and would give spark every now and then.

jetdriverbr Posted January 19, 2007 Report Share Posted January 19, 2007 Any news on the fix? I am having a similar problem with a '97 model. Quote Link to comment Share on other sites More sharing options...
kubiac3 Posted January 19, 2007 Report Share Posted January 19, 2007 If the flywheel is bad you can check it by taking it off and shaking it next to your ear. If you hear rattling then the magnets are loose and its toast. Also i had a no spark problem and ended up replacing the wiring, coil, flywheel, and checking and re-checking countless items. I then just said screw it and bought a new stator even though mine tested good and within 2 kicks it started right up. I had the same "i will spark when i want to" attitude out of my bike as well. You should also check the grounds on your wiring harness and on the coil. Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted January 20, 2007 Report Share Posted January 20, 2007 we had a problem like that on a bike last year after the customer made some wiring harness modifications. I put a new harness in it and it started right up. Does it have the correct flywheel pick up gap? Was it a brand new stator? Is anything else aftermarket like the cdi? Check solder joints on the stator? Make sure the stator yellow and black wires are plugged into the proper harness wires where they come out of the case. Verify proper kill switch operation. (try bypassing it). Make sure the tors wiring is just terminated and not reconnected to itself. Key switch if not equipped may need to be jumped or checked for a fault in its circuit. Coils rarely go bad, but they get a charge of the stator and then have a ramming capacitor on them. I think they only have a ohm check you can do.
