lil_heavy1990 Posted February 28, 2013 Report Share Posted February 28, 2013 like the title says i have no spark after rebuild. the motor ran when i tore it down. i do still have the tors on it but have the brain box removed. ive done a search and cant really find an answer. im a mechanically inclined person but my weakness is electrical. ive swapped stators coil and cdi box off of another shee. still no spArk. the pickup gap is set at .018. i know its gotta be something simple. any ideas? thanks in advance for the help Quote Link to comment Share on other sites More sharing options...
Pastrykiller Posted February 28, 2013 Report Share Posted February 28, 2013 Are the pistons in backwards? Are u sure u have spark? Quote Link to comment Share on other sites More sharing options...
lil_heavy1990 Posted February 28, 2013 Author Report Share Posted February 28, 2013 pistons are in correct. and i have no spark at all. i have tried a stator, coil, and cdi box from a buddies banshee and still no luck. Quote Link to comment Share on other sites More sharing options...
Pastrykiller Posted February 28, 2013 Report Share Posted February 28, 2013 The orange wire in the coil is the +. Check that and then check your grounds. If I recall, there is only one actual ground wire on the frame and the rest is grounded via nuts and bolts from engine to frame and stator to engine.

blowit Posted February 28, 2013 Report Share Posted February 28, 2013 I would suspect you still have the TORS system on the bike and messed wtih the throttle cable a bit when rebuilding. If the electrical system senses that one of the carbs is open a bit but thumb throttle is closed, you will not have spark. Look inside the carb backs and see if a carb is hung up a bit.

Mull Engineering the carbs are sync'd. i have a feeling its the tors. i have the little black box near the gas tank unplugged and removed. shouldnt that disable the tors.?

blowit Posted March 1, 2013 Report Share Posted March 1, 2013 Yes, if the TORS module is unplugged, that should not be your issue. Closely examine all the wiring and terminations (plugs). It is possible that you disturbed one of them during the rebuild. The B/W wire is the ignition kill wire. If it is taken to ground potential, there will be no fire. I recommend testing from any source of B/W (TORS plug) to chassis ground. If you have continuity, there is something grounded on the B/W. Kill switch, key switch, TORS, or pinched wire. You would also test Any black wire to chassis ground to make sure there is continuity. Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted March 1, 2013 Report Share Posted March 1, 2013 You didn't unplug your key switch, did ya? Quote Link to comment Share on other sites More sharing options...
HolySheet Posted March 1, 2013 Report Share Posted March 1, 2013 Check to make sure flywheel is tight and seated on the key. Then I would check and make sure all wires are good. If you still have a key switch I would unplug it and run a jumper wire from the black to the red to rule that out. Quote Link to comment Share on other sites More sharing options...
