Im not sure about on your bike but to get the spark plug caps off (least thats what i call them) you have to be diligent maybe even twist them around a little bit then suction them off of the spark plug. Rememeber they have been hot, cold, hot, cold many times by now and could possibly be a pita. My best method was to twist, then grab the top of the cap as firm as possibly so the wire doesnt pop off, and then pull at an angle. However my number 2 and 3 cyclenders actually broke so i had to replace them, but with 45k miles what can be expected. If any of this helps awesome...if im totally off, sorry.
