Banshee Giving Me Electrical Problems

[Infamous039]

I have a 1990 Banshee that is having some problems electrically. The bike will start when its cold, but once it heats up and you shut it off it will not have anymore spark until you let it sit for a while. I replaced the stator with a brand new ricky stator and adjustable timing plate set at +4. I have interchanged out 3 CDI boxes and it still does the same thing (NO SPARK). I replaced the whole wiring harness with a fresh one, removed the key and the on/off switch, and installed a new coil with new spark plug boots, and nothing changed. I had the topend redone and bored .20 over 2days ago because of low compression and still nothing has changed. I also sanded down all the ground contacts on the frame and still has the same NO SPARK issues once it warmed up. Please help me someone, because this bike is freakin pissing me off and I want to smash it.

 

My mods are listed below:

 

New Wiseco Topend .20 over with 0hrs on it

Stock Carbs 280 main 25pilot, Needle on 3rd clip, Air screw 1.5 turns out

T6 pipes

Prodesign Filter Setup

TORS removed

+4 timing advance

Some one please help.

did you drop the flywheel or hit it with a hammer at all?

[Infamous039]

No, I havent dropped the flywheel or hit it with a hammer

Your gonna need an ohm meter for the next part. Only other thing I can think of without test equipment is inspect the voltage regulator, and the lighting harness.

 

What exactly made you want to try 3 cdi's? Didn't something tell you there was a problem elsewhere when you tried the first one and nothing changed?

 

Is the RS stator a 200 watt unit?

[Infamous039]

The stator is the regular 100watt. I tried three different CDI's to make sure that wasnt my problem.

Well you just needed to try one cdi out to tell its not your problem. What about the voltage regulator and light wiring?

[Infamous039]

I have put a new harness on it, but I have not looked into the voltage regulator or the flywheel but the flywheel has never been dropped

So...new harness, no TORS, new coil & plugs, new stator, flywheel ok, not CDI...have you checked the stator with an ohmmeter? Can you do it cold and then do it again when hot when it won't spark and compare the readings? Have heard of some cases of new stators being DOA or doing funky shit, yours could be one of 'em. I wouldn't worry about the volt reg it's not part of the ignition circuit just the lighting, but the symptoms you describe don't really match anything...hope you find it tho, good luck.

What are you uising for a kill switch? Do you still have the stock light and kill switch on the bars? Cause mine shorted out on me once, and after redoing everything I realized that was it. Try bypassing it with a lanyard killswitch or something.

wiring isnt as much trouble as you probley think it is, you say you have removed things from a NEW harness correct? (my banshee has 4 wires from stator to cdi, then only 2 to the coil to prove how simple it is....)

 

just curious as to how you removed wires? did you totally remove the wires individually including all of the "leftovers" you could have a ground inside the harness if you did a sloppy job. no biggie.

[Infamous039]

I unplugged my kill switch. so now I just shut my bike off by using my clutch

[Infamous039]

I have only cut the wires to the key and tied them together. I unpluged the on/off kill switch completely. Tors wires are still there but taped up into the harness. Everything else is in tact and not been cut.

Hey guys would the degree key have anything to do with the spark once its warmed up???

[Snopczynski]

Why would you run a degree key and an advance plate at the same time? Never run a degree key, they shear and are weak.
