I recently solved a recurring issue by replacing both coils. Left stock coil was intermittent, but acted like a fuel issue when it was misfireing.

Bought both Nology coils for about what I would have had to give for one stock coil, and immediately realized that that left coil had been a bigger problem than I thought, and for a longer period of time than I had thought.

Independent bike repair shop, ordered the coils through Parts Unlimited - said they bolted right up, no mods.

Our spark plug wires are of good construction, and the caps are easily replaced (already done). No reason to suspect/condemn ignitor.

I led my repair shop to Brent's site, and he made me the same deal even though he would have marked it up some under normal circumstances (he has to make a living too). I have spent quite a bit with this shop over the last few years (mostly tires)and trust them explicitly, as they do me - they are not Triumph experts, but have more Bonnevilles and Americas and the like showing up there all the time - nobody from here that I know of.

I speak of Cycle Sports on Clay Road, in Houston, Tx.

Nology works for me!
