I've tried everything i know to do and she still wont run right. so far this is what I've done. new battery, new ngk plugs, cleaned the carbs 3 times, striped the wiring harness and solder all the brass connectors, cleaned and or replaced any bad connectors, changed one of the pick-up coils.
it is not getting any spark to the passenger side cylinder but is getting a big fat blue spark on the driver side (and yes i know it's not a car but it's just for reference) it will run as long as you hold down the start button (I'm thinking i need a Buddha carb job) any help greatly appreciated i"m at a loss thanks,

Hi James,

Ok, so the right side gets no spark?  How are you testing it? Check the wires going to the  coil with a voltmeter. Turn key ON, should see at least 12volts to each of the terminals.  If you don't have a meter try a test light to at least see if it's getting any juice.

i checked it and it's getting about 8.4 volts, i checked the wiring harness and it's only getting about .06 ohm's between the coils and the plug in the rear of the bike (the one it said to check on the form) I'm starting to think that the ignition control module may be going out,

are you saying that you check each one? like the frame of the bike and one terminals? like one at a time?

I'm not an expert but here's how I understand it.

Let's work backwards.  Secondary, Primary, and Trigger. 

2ndary: The spark plug/spark plug wire & cap are part of the secondary ignition circuit.  If you're not getting spark move back up the chain of command to the primary. 

Primary side: Terminals on top of coil (orange/white), lower connector on ignition coil (black/yellow  or white)should get approx 12v with key on and engine off. If ur not getting near 12v either your battery isn't full charged or you have a poor connection somewhere.  Make sure battery is fully charged b4 getting started.
-KEY OFF:Check resistance btwn both terminals on coil.  Spec. 3-6 ohms
-KEY OFF:Check resistance btwn lower connector and spark plug cap  Spec. 18-30k ohms
-KEY ON:Touch tip of test light to lower connector and crank engine over.  Light should flash on/off signifying the trigger is working.

Trigger: Ignition rotor/pulse generator coils/ ignition module.

Pop off the ignition rotor cover and start testing from there to the ignition module.

The experts will chime in I'm sure.

thank you bud I'll have to mess with it tomorrow to test that stuff but you gave me something to do anyway i was unsure about the plug boot one, and I'll do my best to get that bolt mailed out to you tomorrow

all right i tried everything you said to i even swap  the coils from right to left all the voltage was good, and the ohm's was @ 18.9 so i think that they are okay any one know what else it could be? I'm really at a loss, could it be the pick up coils? whitch one is used for the right side? the front or back one?

oh and the way i tested it was by pulling out the plug and grounding it looking for a spark it worked on the other side. sorry i missed that last time

Ok, so everything checked out ok?  Does it still not get spark on the right side?

no it still wont spark on that side even though all that stuff is working. i really don't understand. what should the ohms for the ignition control mod be? or where can i look them up?

oh and ps ATLRIDER i sent that pinch bolt yesterday so you should have it by this weekend

Atlrider gave expert advice even if he doesn't realize it.

It sounds to me like the problem is in your hand, the spark plug.  I know it sounds ridiculously simple but it would perfectly explain your symptom and why you can't find anything else wrong with the ignition system.  Just because a plug looks good doesn't mean it is.  The insulator can crack where you can't see it and it can allow the spark to reach ground without reaching the electrode.

okay I'll go buy another new plug tomorrow when i get off work and try that. but I'm thinking i may need to try cleaning the carbs again thanks guys i really appreciate the help

could it be the crank trigger? is that a possibility? i was reading that you cant check them to see if they are bad. which one works the right side?

Thnx, but definetely not an expert.

James,

I hurt my back and have been out of it.  Haven't really been checking this thread.  Anyway, having any luck?  Bill recomended spark plugs.  Let us know after you change them.  If it doesn't change anything and ur sure the ignition isn't working, can try some other stuff.

I'm gonna change the plugs tonight but i may not get to try it till Sunday or later, one of the retired fire chiefs where i work passed away yesterday so I'm going to the viewing Sunday and the funeral Monday so pray for his family 

got the new plug's still not getting fire whats next?

are you getting power to your right side coil?

Have you tried pulling the plug on the right side? Leave it attaced to the coil and place it near one of the engine fins while trying to start the motor. If your not getting a spark then I would definetly change the plugs and try the bike then.

If you tried everything and they checked out ok, you should be getting spark.  Did you try the test light on the coil terminal to see if it flashes on/off while cranking the engine?  If it's flashing no need to check the trigger.  In case it isn't flashing here's how Haynes manual says to check it.
Disconnect the 3 terminal connector from the ignition module on the left side of the bike, near battery. Check the wires that have the female connectors, not the prongs.  You have a brown, black/blue, green wires.  Set meter to ohms.  Touch one meter lead to brown and the other to black/blue and record the reading.  Then touch one meter lead from black/blue to green and record the reading.  The spec. should be btwn 250-420 ohms.

One other thing you can try is to unscrew the cap that goes over the spark plug and trim approx 1/4 inch from the wire.  This will expose a fresh piece and may give better spark.

Edit:  Almost forgot.  Disconnect (-) battery lead.
