a couple of years a go I did a stick coil mod on my bike because of a misfire, one thing I can say is I won't go back to the old type coils as there is more space on top and the cam cover looks neater. I had to recently replace one of my coils due to someone cutting the wires to one and stealing it!! I was lucky in that I found an already modified harness off eBay that looks better than my original. I will post some pictures when I get a chance.
