Dyna Coil Question

Hi there.

I have a newer set of 3 ohm Dyna coils (the green ones) on my parts bike. I would like to transfer them to the bike I am currently working on. Both bikes are 1981 KZ750 (4 cyl).

With the stock ignition, are these coils direct bolt on, or do I need to modify anything?

Thanks for the help.

Just plug it in.

Excellent! Thanks for that. I was getting a little confused with the addition or bypassing of a resistor in certain situations.

Thanks again.
