I spun it in a couple of turns and it started on the second kick. DOH!!!

By any chance has either STFU or Christian played with the idle adjustment?
yeah I did, when it initially wouldnt start....

howvere I have tried all manners of turns in and out and it still just wont start...

yup I get good resistances on both coils...I also sanded some new steel so the mount had a good ground...

whats your way of checking spark?

hey dudes I have never had good results grounding the plug to the head, I mean how do you get it to not move? in any case I heard of guys holding the plug wire in their hands Im about to try this as I just cant figure out how I get zero overnight...unless electrical of course

thoughts?

Take a deep breath and find a starting point. From there, check all connections, looking for broken wires or shorts. It's in the ignition circuit somewhere. Won't start after a ride? Were you playing in the puddles again? Something get wet? You could grab your spark lead and kick slowly and see if you get a tingle. How about your headlight? Can you get a few volts there? Patience Grasshopper, you will find it.

thanlks jab
Im starting from simple

Headlight is off

kill switch is off

I have my red black from statir and green ground...I have my whight connected to the blue lead that goes to my voltage regulator...

I have cleaned double and triple checked all connections...
I have not taken apart the harness

I get no tingle in my hand when holding the plug in my hand

should I try without the plug and cap? just the wire?

thanks

Im getting 35volts AC when kicking over

ground on the coil looks good and has clean steel to ground too...

can you get a voltage reading at the coil? like black yellow and green?

Im getting some voltage at the cdi red and black...

again from the stator im getting close to 40vac...

Im undoing the harness kindof as we speak

I get no spark or tingling when holding the coil lead...nothing...

still testing

alright guys so with a test light I confirmed Im getting no volts at the coil...at the black yellow...

I am getting volts at the black red...

it seems that either the wires or plugs out the cdi are wonky or the cdi

here is my question

if something is shortted for example, when testing the good backup cdi I have would that damage it too?

reason being is GET nothing with both cdi's

so whats up?

please any input is appreciated...

christian

You're getting power to the coil, right? And you are getting signal to the coil or CDI? Can you test the resistance in the coil all wires off?

This is painful to watch, so I am going to chime in.

1. Remove the spark plug.
2. Put the spark plug in the rubber boot ( of course you have checked the coil lead wire and the connector inside the boot to make sure they are in good shape)
3. Find a way to clamp the threaded metal part of the plug to a good steel surface on the bike. (grounding the plug) This can be done with a friend just holding the plug again a head bolt or by using duct tape, or a spring clamp, etc. Anything that can serve as your third hand.
4. Now get on the bike, and while you are squeezing the decompression lever in with your left hand, use your foot to kick over the engine a few times. It will kick easily withe the plug out and the decomp lever pulled in. (Maybe you don't even need to pull the lever in)
5. You, or your friend holding the plug, should see a nice consistant spark.

If you have good spark, my bet is on the pilot jet being plugged.

Unless you have 2 toasted CDI's they are probably good. Trace the dead wires back from the coil. Forgive me, but I am guessing, sitting here at my desk.

dude its painful to watch because I have exhasuted most options

I have no voltage going to the coil

I do not have spark

I do not get tingling at the coil wire

plug cap is new
coil is new
resistances are good on this coil and old oem coil

I kick over and get nothing at the coil

Im checking the harness for shorts and cut wires and nothing

seems like its the cdi

problem is I had a backup and it does not produce anything either!

im guessing the red black and one of the greens?

Can you check continuity from the CDI end of the harness to the coil?
