Still got a misfire

[shrekster]

The standard Yamaha plug caps are not the best quality in my experience. I noticed this by accident on my mates fazer 600, fired the bike up in his garage when it was completely dark and noticed all 4 caps were showing visible sparks on the outside of the caps. They were arcing all over the place, spoke to a friend who is a  Yamaha technician who said he changed all of his own bike caps for jet ski ones. I have done this on both my Fazer 1000 and my R1 and noticed a smoother idle especially on the Fazer.
