Dual plugs and single fire


Post by Guest » Thu Oct 25, 2007 1:16 am

Evening all,
I'm looking for pics/ideas for mounting two coils in a rigid frame/3.5 fatbob motorcycle. I'm going to dual plug with a single fire distributor. I run a CV carb so I don't think mounting a coil from the top motor mount will work out.

I think Dyna makes a four tower coil. Check Jireh, they carry it for around $125. Kinda bulky, but does the trick. You can also check out the mini-coils they carry, if you wanna hide 'em.

I run two coils on my panhead. One in the stock location (fires the rear cylinder plugs) and the other mounted to the top motor mount (fires the front cylinder plugs). I also have a CV40 carb and there is no problem mounting the coil on the top motor mount and still having room for the CV enricher cable.

Here is a photo of the two coils installed:
