If, due to Google's organic search results, you arrived here with the intent of replacing the head light bulbs of your KLR650, I implore you to reconsider. It is simply not worth it. Take my advice and just sell the thing. It will save you a really big headache.
Accessing the headlight of a KLR 650 is more difficult than teasing an orgasm out of a eunuch. The Clymer manual reads like the blueprint of a Rube Goldberg machine. Direct quote from the manual:
1) Headlight Inspection/Replacement: To access the headlight, remove the front fairing.
2) Front Fairing: To access the front fairing, remove the rear fairing.
3) Rear Fairing: Unscrew anything you can see, put the screws in a little pile, unscrew anything exposed by the first round of unscrewing, and repeat a few times until the motorcycle is sitting in a pile on the ground.
4) Root around the pile and find the light bulbs, throw the old light bulbs away, reassemble by reversing steps 3 to 1.
I sat down and cried.
