haunted banshee

[IROOST1]

every time, it seems like this thing is haunted. this morning, it took 2 kicks to ride up to my truck to go out to the track, but it was sitting for 2 weeks since the last time i started it. otherwise, it would start on the first kick. I get to the track, starts right up. runs fine all day except my throttle stuck open in one corner, but i got it to pop back down. when i got home, i unloaded it from the truck and started it to ride it back to put it away. and it sounded like it was only running on one cylinder. so i changed out the plugs, now it wont start at all. and it has no spark, in either cylinder.

 

and yes the handlebar switch is on, the key switch is removed. wtf. what the hell can be wrong. i checked all the wires and the coil. nothing is loose. i dont understand it. this thing seems like its haunted because it nevers want to stay running good.

I think if you were to ask Brandon who goes by the name "blowit" on here you might learn that he has alot of experience with CDI's and stators causing similair symptoms when they begin to fail. :thumbsup:

Well I guess the first thing I would want to know is if you have the TORS goods still in? If so, simply unplug them and check for spark. After that, simply check the resistance in the stator ignition side coil, and the ignition coil. Pull those darn plug caps if the coil does not check out. They like to come lose over time.

 

I would like to know what it has done in the past to determine a coil or CDI problem but most coil issues get worse with heat or don;t work at all. If yours is very intermittent, you may simply have a wire coming lose somewhere. watch those blade connectors on the ignition coil. I caught one like this a while back and someone had "spliced" some wiring around the steering stem. When the clutch was in, it killed it. This just happened to be because the cable was laced with the harness and pulled the wires apart when the clutch was in. Sometimes you have to look for a pattern in the failures to find the source.

I just want to add something here. Although it is probabally very unlikely, but don't rule out the plugs. It would be hard to believe they could both be bad but it could happen. On my CR125 I put in a new plug after it sat for a while and couldnt get it to start, pulled plug I had spark, so it got kicked some more. Well I eventually gave up for that time and cleaned the carb out a week or so later, still wouldnt start. Well after dragging it with the banshee, checking spark and fuel many times I figured what the hell and put a second new plug in and hmm it ran fine. For some reason the first new plug would fire out of the cylinder but not under compression so I basically spend alot of time and frustration over a really easy thing. So even though they are new dont rule them totally out, it dont hurt to try a second set, who knows maybe you will get lucky and itll run.

Yeah the porceilin iinsulator around the conductor of a plug is very hard and not very resistive to shock loads. A good drop on the ground can do it. This will cause current leakage to an alternate ground, generally through the plug housing and right to the head. This can be very hard to detect because your multi meter will not find it and even putting low voltage to it will not find it. You simply have to use a high voltage plug tester to find it or replace the plug in question. The tester will induce several thousand volts to the plug and measure the spark in distance. The higher the voltage, the more insulation you need to hold back current leakage.

 

You never know if your plug was dropped by the parts guy before you got it.

 

Good point on that one.

The tors are removed. I will check the resistance when i get a chance. I have had jetting and a air leak problem before but those are taken care of. The current coil i got used and put new ngk caps on it. I have two others if it is bad. But i dont have another stator if its that. I checked the wires and dont see anything pulled or stripped. I just done get why it would be fine then just fart out.

I checked the orange wire with a check light and that worked. I couldnt check it with the multimeter since the batteries were dead. So i swapped out the coil. It started after that. Thanks guys.
