Im not getting any spark from one of side of my 2 cyclinder kawasaki ninja 500 EX. Its an 1987. I have replaced the plug wires and the pickup coils. I switched the coil packs and both work. Im just not sure what else it could be.

    I have the same problem with my 1987 Vulcan 1500 (88SE). After a cold start, for the first 10 minutes of operation the engine will fire on only one cylinder unless I pull the plug wire off and let it arc from about one-half inch away. (Needless to say, this is occasionally a shocking experience for me.) Eventually, it begins to fire normally and I can slip the cap back onto the plug. I have replaced the ignition coil assembly and plugs.

To my knowledge, a 1987 Kawasaki EX500 uses a TCBI with digital advance to fire the ignition coils upon receipt of pulse from the trigger/pickup coils.

Since the pickup coils are new, and you have swapped the ignition coild, replace the high tension wires and checked/replace the spark plugs, the the only cmponent left is the CDI (electronic ignition system).

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Kawasaki Ninja 250R will not rev past 5000 RPM

Hi, Tyler and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage check for spark leakage in the dark.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.

Left coil feeds 1 and 4...right coil feeds 2 and long as you stick to this it doesn't matter which lead goes to which plug. Left coil will have one short lead and one long...short =1...long = 4. Right coil leads will be about even in length...doesn't matter which goes to 2 or 3.
It's a wasted spark system so plugs 1 and 4 fire together...2 and 3 fire together...only 1 cylinder in each pair will be compressed and ready to fire when the spark happens, the other will be empty and coming on to it's inlet stroke...

How can i tell when my 2002 kawasaki ninja 500R needs a tune up?

Check the maintenance schedule in your owners manual or on The 500 requires a valve adjustment and carb sync every 8000miles. Spark plugs should be checked and replaced, if fouled at the same time as the valve adjustment.

I tired to bypass the switch and put all the wires together lights came on and its turning over but im not getting any fire to the plugs ninja 500ex

You need the stock ignition switch in order for it to trigger a relay inside the igniter, then it will spark, this is part of Kawasaki's anti-tamper proof ignition system.

I just picked up a1986 Ninja 1000.Sometimes it runs on all 4.But most of the time just 2I just checked and the right side coil has continuase power.What might cause such a thing? Please help Iv been at it...

Its definitely sounds like ignition parts or wiring... What parts did you replace on the ignition? I am not sure on the ninja 1000, but some of the Kawi's use 2 pulse (pickup) coils off the flywheel/magneto, You can do a simple Ohm test on these (if applicable).
You can also try swapping the HV coils around to eliminate those.
Then of course the ignition module, or CDI ...
I am sure you probably checked all your grounds and connections...
