I ran into some trouble today when pulling the coil pack off the spark plug underneath the gas tank. The plastic part that goes down into the engine came off fine but the rubber housing remained stuck to the spark plug, I assume. I tried pulling it out off the spark plug with needle nose pliers but it just pulled the rubber apart in small pieces and scratched the inside where the coil pack goes. What should my next step be? I had no trouble removing the other spark plug before removing the gas tank and attempting the other. Did I cause much more damage by trying to remove it with pliers and now need to replace the entire coil pack? Is this also a common problem or did I do something wrong?
I've seen this before. The rubber sticks to the plug. They should have been installed with silicone grease.
Shouldn't have happened on such a new bike. It usually happens with higher mileage cars.

Well after many hours of frustration and calling my local dealer for help I was S.O.L., so I though, except for bringing it in for them to fix it. I then stumbled upon a car forum this morning and it said that a wire hanger does wonders. The first thing I did after getting home from school was cut a wire hanger to a point and bend it at a ninety degree angle. This allowed me to get underneath the rubber and pull it out! I was so happy when I saw it coming up! Problem fixed.

No, I didnt put any on. I would have if I had some though. I'll just keep my wire hanger in the tool box.
The coil rubber adhered to the smooth surface of the spark plug. Most plugs are ribbed but these are smooth. Use some silicone grease when reinstalling.
Personally, given that you had at least some trouble, I am surprised that you did not put dielectric/silicone grease on the boots when you reinstalled them. The problem is only going to get worse with age, and it is possible the factory forgot the grease on that one which is why you had a problem in the first place.
Glad you got it worked out, did you replace the boot on the coil?

Does silicon grease have petroleum in it? This would eat away at the rubber sleeve.
I have Blaster dry lube with PTFE that is good with plastic - and I assume rubber.
