Okay, I know its been covered in general, but I can't for the life of me figure out how to remove the spark plug cap without breaking something. (yes the tank is already off) Do I need to remove the top motor mounts? Does it come out easier to left or right? Should I disconnect the coil to provide some slack. Everyone talks about doing it and I feel downright unworthy of calling myself a good shade tree mechanic, ....oh the horror, ....the horror. Please help before I write something obscene on the side of my bike. :thumbsup:

Just tilt/twist and pull. If that still wont get it, pry it off woth a flat blade screwdriver.

I use a gasket scraper (1" wide), slide it under the cap slightly and level the cap up, then she comes out really easy. What ever you do dont pull on that lead :thumbsup:

Install a coil on plug and you wont have this problem!!! Just pull the coil and its off. Good luck

You can also apply an air nozzle to the drain hole in the side of the head. Hit it with a burst of air and voila off it comes.

You got me on this one :awww: So you cant get the cap out of the well due to?? does it hit the wiring loom/throttle cables? or is the high tension lead not long enough to get the cap out of the well? ( if someone previously cut back the HT lead and reterminated it this could happen) If this is the case just unbolt the coil and out she'll come

Mystery solved - it is most definitely required to remove the upper motor mounts. Once done, comes right out.

Was the wire routed through the upper motor mounts?

You shouldnt have had to do anything but remove the tank on a 2001, if you think it is tight in a 2001, try a hayabusa cap on a 2000, you wouldnt think it would ever come out. It does
