If you cant turn your key to the OFF position on your 2005/6 Kawasaki 636, you don't need to remove the triple tree to fix it, instead you can just do this:
Turn the bars far right, look under the triple tree at the ignition and you will see a tiny hole toward the top. Take a can of graphite lock grease, or lockease, and use the spray attachment to spay a bunch in that little hole. As you are doing this, take a thin screw driver and push up and down the parking lock (little metal cube sticking out under the ignition. Spay this with lock grease as well, and really work it in there. Spray inside the hole again, while turning the key to different positions including OFF, LOCK, ON, and P. After lubricating the system, the issue should be fixed.
