Katana coils?

I thought I read somewhere here that Katana coils would work just fine on our bikes. I have access to a set from a 2005. Does anyone know for sure if these will work? This will be one of several upgrades planned for my ride this spring. Still about 4 months away from riding weather

Ignition coils?

Measure the resistance. If you're running points you don't want less than 4 ohms or so. If aftermarket electronic, no less than 3 ohms. If OEM electronic I have no idea, but a lot of modern coils are like .8 ohms and they won't work with old ignition systems.

If you are running electronic ignition they will probably work fine. I have a set from a 96 GSXR600 on my 1100E and they work perfectly and bolt straight on to the mounting lugs.

O.K. I got the coils from a 2005 Katana. Great shape,like new. How do I check the ohms and what am I looking for? I do have the stock electronic ignition.

Go from wire cap to wire cap end, There should be ~ 13k ohms if they are 3 ohm coils. You have to add 5k ohms per wire cap, and since there are two caps that are connected through the coil then that's 13k ohms..

The ohms are on the low-voltage (primary winding) side of the coil. Measure across the input leads, not the output.
