I've not had to change my 2011's plug yet, but the first thing I did when getting my bike, was to go over all fasteners to get familiar with the bike.
I had a pad and pen, and made a list of all sizes needed for general take down, and maintenance.
Went to local discount tool shop, and bought whatever I couldn't scrounge from my existing tool supply.
Found an old leather handlebar pouch, and put everything in it. Now when doing anything to bike, I try to use that tool kit.
Hereís a list of what I put togetherÖ http://www.powers31.info/2011_KLR650.htm
( Scroll down to just below second pix. )
Note: some items may have been changed or added since this list was made. Been intending to recheck the list, but you get the idea.
Donít know about your OEM tool kit, but I didnít find much in it that I could use.
