Motorcycle Repair: Ignition testing, kawasaki klr 650, electrex usa


Question
I just bought a 1994 Kawasaki KLR 650. The other day while putting on my riding gear, I had the bike idling. Then for no apparent reason it stopped running, After much frustration and a lot of trouble shooting I found that I was not getting spark. All the safety switches have been bypassed by the previous owner, including the diodes. The plug is new and the wire and coil check out as far as I can tell with my meter. Everything points to the CDI, but that's a $300 gamble. I've tested according to the shop manual and some of the readings are bad. Is there any replacement for the stock CDI? Either aftermarket or off another bike that could be used with some modification? The stock # is Denso 21119-1272. I see a lot of aftermarket and other bike and ATV CDI modules for sale, both new and used. Or can you recommend another test to help me confirm that the CDI is the problem?

Thanks
Rich


Answer
Hi Richard,

Sounds as if the CDI is defective as described. I know of no other tests aside from those mentioned, with the exception of comparing with a know good unit.

I trust and recommend Electrex USA "www.electrexusa.com" for high quality electrical components. Check their website for your parts.

I don't have access to cross-reference part numbers. Manufacturers are not helpful in that respect. Not sure what other model shares the same CDI. Avoid using another model's CDI unless certain.

Shop around for parts on Ebay and forums such as "www.motorcycle-usa.com" and "www.atvfrontier.com" for replacement parts.

See microfiche parts here: "www.buykawasaki.com" or "www.bikebandit.com"

Once Kawasaki's site opens, click green text "Vehicle Information" from the menu, and then "View Parts Diagram" from the menu. A new page opens, select "Motorcycle" from the menu, (or enter your VIN for the “history” of your MC). Select the year, make and model from the menus that follow.

With Bike Bandit, click "OEM Parts" and then select your MC from the menus that follow.

Respectfully,
Mark Shively
