Headlight keeps blowing???

Maybe the volt regulator is blown. It's a small aluminium box with two or three cables coming out. They are usually mounted under the tank or in the steering head area.

I'll bet someone has an answer for you there.

I have the same bike and had the same problem two years ago. Remove your fuel tank. Behind the steering head there is a small pocket in the frame. Inside this pocket is the voltage regulator, a small gray box with a wire and a female spade connector. Remove this pile of junk (very few people I know have one that actually works). You can replace it with a $15 Moose voltage regulator. Several people will tell you the Moose regulator won't fit in the pocket. That's BS! I got mine to fit just perfect using only a longer bolt.
