Thanks for the reply/ Info. Just wondering, have you done any research into those coils, per part # to see if there are Known issues?
The COP is a good Technology, but sadly, like a lot of components these days, longevity can certainly be an issue.
On some of the systems coil failure is pretty high, but then such can be said for some of the coil Packs.
I think if I was using COP I would have a spare with me, for sure on any longer trips, or a ride into the mountains.
There are certainly some really good twin fire coils, that are extremely reliable out there. I have Accel Coils on my KZ1000, and noticed the same, starts better, runs better, etc.
Remember, those COP systems put the coil right on the head=Heat. What causes the most electrical component failures? Heat.
