OK, not sure if anyone is interested, but I thought I would do a quick follow up regarding my thoughts of my new accessory.

First off, the primary reason I did this "upgrade" was to streamline the look on the left side of the motor. I am very happy with that and have even received several compliments already. To be very honest, I have not been able to tell any difference in terms of performance.

The installation:
1. I had to remove the gas tank. This was the first time I did that. It was not bad at all. It is very straight forward. The two tubes that snake through the frame came right out with only a minor tug.
2. The directions are missing one critical piece of information. When removing the ignition coil, the battery hold down bracket also has to be removed and cannot be put back in after the coil is removed. This is because the two screws that hold the ignition coil in place go through the battery hold down bracket first. This is not a big deal but it did give me a pause.
3. When routing the cables from the coils, i pushed them through the frame between the cylinder heads and then up to the backbone. I zip tied them flat to the side so as to fit in the channel under (and on the side) of the tank. The wire routing was the easiest part of the whole job.

The future:
1. I do not look forward to ever having to replace the spark plugs. I am kind of glad I did it now when I put these coils on. (I switched to Screaming Eagle plugs.) In order to swap out the plugs in the future, the coils will have to be removed. I fear that will require removing the tank again. There are two socket head cap screws that hold down the cast aluminum covers to the cast aluminum head stud mounts. Getting to them without removing the tank will be tedious at best. I really do believe that removing the tank will just be quicker than micro/mini turns of a right angled 5/32" hex key wrench.

Final thoughts:
Removing the fuel vapor vent tube was able to be done without cutting the zip tie that held it to the frame. I was also able to put it back in the same zip tie when reinstalling it. It is a pain in the ass rerouting because of the tight placement against the rear of the primary but I got it done. Ok, I made my son help son because he is young and has small hands.

I hope that helps.

P.S. If you look real close at the picture attached, you can see where the fuel vapor vent tube is not quite routed correctly. I will go take a picture later today and add it so you can see it now.

Nice review yegg. The Accel COP setup certainly does clean up the engine nicely. I put a set on mine about a year and a half ago, but ended up taking them off because like you, I thought about how much of a PITA it would be to change the plugs when needed. I hope you used loctite on the screws to prevent them from loosening up over time with vibration and heat cycles. I experienced this once, even with the use of blue loctite. I used more loctite the second time around and they stayed put. When I took mine off, the cylinder head bolts were marred from the COP allen head set screws. They were also starting to rust a bit too. I bought new cylinder head bolts to correct this once I removed them for good. In the end, I gave them to my buddy and he had them sandblasted and powder coated charcoal gray to match the engine on his 2014 CVO Limited. If Accel ever comes out with a revised design that is more user friendly and won't cause damage to the cylinder head bolts, I will consider buying another set.
 
One other thing I forgot to mention to you yegg was, I used four aluminum spacers (stacked two on top of each) that were the same diameter as the stock coil hold down bolts to raise the battery cover locking tab back to stock height, so that it would still function the same as it did with the stock coil in place.
 
I like that idea. Thanks. I was considering putting the cool back in too. I'm not sure why it had to come out. It certainly looked like it could have remained.

Yes, the coil could have remained in place. If you decide to put it back in, I recommend getting some rubber vacuum caps and putting them over the spark plug and electrical ports to preserve them for possible future use.
