    What size are the cylinder nuts? 13mm is too small, 14mm is a hair too big (and rounds off the nuts). Standard sizes do not fit either. Head shape is too funky to get a socket on them.

    I haven't looked at my 2011 recently, but the last time that I rebuilt the top end, I didn't have any problems with the cylinder base nuts. Standard metric. Should be the same hardware on your bike. I'll go over to storage and double check the size when I get a chance.

    I went over to the storage unit today and checked out the hardware size. The cylinder base nuts are 14mm. They do seem to be alittle easy to slip off of, so choose your wrench wisely and make sure to keep constant downward pressure on it.

    using a quality wrench makes a difference, I use Mac and Snap-On

    Once you get them removed, It might be time to go with new ones, and get yourself a 6-point box wrench for just that location.
