Both coils were new 22 months ago....I broke the #3 wire right at the top of the ngk cap back in the middle of July. I jerry rigged it for VMD, but when I went to fire it up at the show...was only running on 1,2,4. Got it home and lost #2 also. so bought new coil and have been wanting to get rid of the ngk caps since they don't even look oem. Babbits had it all at a very good price....not much more for coil and 4 caps as compared to local honda dealer price just for the coil. one thing u might want to try is to start the bike in the dark and look for any spark leakage around the caps, wires. I was lucky that I knew what my problem was since I created it.
