I am putting this out there because it has cost me $240 and might just save somebody from making the same misstake. Their was a post a while back asking about how to change a plug. The answer from sir Grayracer was to remove the tank. I said you could do it without removing the tank but it was tight. DON'T DO IT! You can get the plug cap/coil off with the tank on but it is a very tight fit. In fact it is so tight that you will crack the coil and when it gets hot it will start doing funny things like quiting. The first coil that went out I thought was a fluke. That was on my 06 a couple of years ago. This last time around it went out on my 08. I swaped parts with my friends bike till I found the problem then realized I had cracked his too. Three coils @$80 each! So, If you need to change your plug, pull the tank, disconnect the wire to the coil then pull it out.
