Swapped out my spark plugs today and thought some of you would like to see some pictures. I was doing an oil change as well, and I like to fully disrobe the bike when working on it, so I already had the tanks off. (You would only need to remove the right side tank to access the spark plug.) Access to the rear cylinder is easy enough. The leads from the CDI box disconnect at the top of the coil. The coil then pulls right out. Use your KTM supplied (should you be so lucky to have one) spark plug wrench and pull that puppy right out of there. The front cylinder is quite a bit trickier, but its doable. The radiator fan boot is kind of in the way, but I didn't have to remove it. Disconnect the wires and pull the coil. Drop the first part of the spark plug wrench into the hole and wiggle it into place with your fingers. Then use the handle (don't use the extension) to turn the plug out. It's slow going, but entirely possible. Here's a shot of the plugs, before and after.
