Unable to test. Must verify other components in system, if they are all in spec. Than it's down to cdi.

SOURCE: no spark

It sounds to me like the repair shop has connected the ignition wire ( the wire going to the + side of the coil ) to the wrong switch terminal. Take a volt ohm meter and connect the ground wire to the negitive ( - ) side of the battery and expose the ignition switch terminals. With the switch in the OFF position check for volatge on all the terminals. Make note of any terminals showing a 12 volt reading. That is probably the feed line from your battery. Turn the switch to the ON or RUN position and check for a terminal other than the one which gave you a reading before. note and mark this terminal. Locate the coil. There are 2 thin ( 18 guage ) wires attached to the coil. One goes to the distributer and the other goes to the ignition switch. Isolate that wire and reattach it to the connection on the ignition switch you marked earlier...
Good luck,

Replace the magneto/stator, CDI and voltage regulator/rectifier. Usually if one messes up they all go bad.

No spark, it was running find and sudenly stoped. ??

More than likely it's your ignition control module or cdi/coil pack. It happened to mine years ago. Ypu can test them with a voltmeter for resistance and voltage output. Hope this helps.

ECU gives no spark signal towards coils, ECU tested ok..

Try bypassing the side stand switch altogether & also any safety switch on the clutch lever, sounds like some sort of wiring issue or maybe a bad stator plate.

No spark but sending out a signal and changed and checked wiring and CDI but no further luck

If it is a CDI unit it could be that even tho it my test ok.
If you have not all ready done so, take it to a bike shop and get them to test it under load. It should only cost a few dollars to have this done.
And change Spark plug even though it my look ok it could be shot.
And make sure that the CDI has a very good earth.
I have found this problem with one of my bikes in the past and this fixed mine.
Hope this helps

I have a chance to pik up a 88 yz 125 for a hell of a price and the guy says it wont start. No spark. electrical problem. says its the stator. I dont know that. So im asking, what exactly I can do to find...

hello, usually you have 3 things for firing problems, stator and stator pickup coil, or ign coil, or cdi, i have a 2000 warrior 350, i just went through all that, you can buy after market cdi from procom engineering inc. i purchased one for my warrior 76.00 , it advances timing, hotter spark etc.most of the time it is the stator, pick up coil, both are hooked up together in the stator case, left side of motor,warrior cdi usually goes bad, havent heard of cdi on 88 model, may need to check with dealer.

No spark on 1998 Cagiva Canyon

did you check the primary coil? the ignition coil?if you think that these are all good,then you must replace the CDI.You cant test a CDI if this is good or not because it is a form of IC or integrated circuit,unless you have a manufacturer's diagram of it.You can check it by by detaching into its plug and get and replace an old CDI which you know is working,for example,get the CDI of the other motorcycle (if it has)the try to plug-in ,and if it fires,then thre you can surely know that the problem is on the CDI.
