Dyna Coils Kit

You’re reading this likely because you’ve heard about improving the ignition of your carbureted Monster or SS.

The whole motivation of developing the Dyna kit was the discovery that the Nology coils wouldn’t work with the black ignition boxes found on Ms and SSs starting around 1994 or 1995. As copied from my aftermarket page, the Ducati factory changed the ignition modules used to drive the coils at some point near 1995. Previous units had a midnight blue potting (or expoxy or filler). These units have black potting.

The ignition modules with the black potting are not compatible with Nology Pro Fire coils. The Blue boxes were of high quality using a Dwell type of excitation. The newer ones I believe are simpler transistor type that run the primary current through the coil at higher values. This causes the Nology coil to get very hot then begin to break down. Continued running will melt out the red potting of the coil and the ignition module will soon follow!

It is possible that the factory went back to the blue boxes around 1997 or 1998.

The Dyna coils do not readily bolt on to the stock coil mounting bracket. I also read about folks that had problems with them hitting the gas tank as well as other folks drilling holes in the airbox so the coils core could pass down into the airbox. Some folks cut the coils, etc, but no one was truly happy with the install.

Step in the aggro machinist whose bike just blew up some Nology coils and stock ignition modules and some RD is gonna happen. We came up with mounting brackets or adaptor plates that the coils would bolt to, which would then bolt right on to the stock coil bracket. We, too, found the clearance issue, so we saw off the extra unneeded hole in the coils’ cores.

To make the kit a proper bolt on, all of the necessary hardware is included. Also, brand new NGK silicon wires are cut to length with the proper connectors for the coils installed. New terminal lugs are included so that there is no splicing required.

Unclip the connectors from the stock coils and they go right on the clips included in the kit.

Instructions are included. There’s 5 pages, printed front and back with a lot of grainy pictures.


Zina’s bike was the first true testbed and she noticed that while riding in the canyons, the bike would not stumble anymore when it would in the past. Mostly at lower rpm with high throttle/load. Also, I didn’t cheat with her kit by installing new plugs.

I really wanted to see if she’d notice – and she did!

Among the first batches of kits to be sold went to the UK. Here’s actual customer e-mail:

Thanks, Nick. I will!

I build these kits in relatively small batches, 5 to 10 at a time. I’d do more, but there’s too much cash outlay to have a lot of them on the shelf at once.

On a related note to Nick’s mail, Zina’s bike was down for a while because her Pro Italia clutch slave cylinder failed and I had to wait for a loaner cylinder from a friend before she could ride again. (In the interim, she has become infected with the fruit of the 4 valver!) Anyhow, I installed the loaner and started her bike up after having been sitting for almost 3 weeks and it was so crisp on start up that I couldn’t believe it. We’ve got the Yoyodyne unit now, so it’s all good.

How about some more feedback:

Thanks for your kind words, Scott. =)
