July last year I installed new coils on my 450. I bought them from Dime City, but they are they same coils as sold from Mike's XS. In addition, I went to iridium plugs and non-resister NGK plug caps. I will say, that initially my condenser was not grounded and so the bike "tried" to run for maybe 5 minutes and in that time the coils were kinda warm. I figured out the issue and promptly grounded the condenser and I was back in business.
The bike ran fine the rest of the year (although I don't remember just how much riding time I did on it afterwards). I decided to have my carbs tuned on the dyno so this past March I fired up the bike and rode to the shop. Ran perfectly fine. Dropped it off and got a call a few days later that while the bike initially ran just fine, the right cylinder is no longer firing and they determined it was the coil.
I bought another coil, installed it and the bike is running properly again.
What I don't understand is why the coil went "bad". I asked them to test it and tell me what the ohms read and they said the primary side was giving only 1 ohm.
Is there anything wrong with my setup... my plug wires are copper and as I said before I'm running iridium resister plugs with the recommended non-resister caps? I just don't want this to happen again, but next time while I'm out on the road!
