Just a guess... Maybe your R/R is dying, and making too many volts when the bike is reving.
Try messure the voltage on the battery poles while reving the engine.

A bad ground would effect both the low and the high, since these are H4 bulbs, they share a common ground. The high beam pulls a lot of voltage (compared to the low beam), and if your R/R is going/bad, it will give too much current, blowing your bulb.

It's no big deal to take apart the left side controls, or the right side for that matter.Two screws and your in! Might be a good place tostart. Check for loose orbroken connections in the switches.

I believe this to be incorrect. They share the same power. The low beam has its own ground as well as the high beam. Switches control the ground side, never the power side. If you've ever noticed on your bike when you have the headlight on at idle its not as bright as it is when u free rev the engine. When you rev it gets brighter b/c the r/r gives the bike more juice. Sounds like its a bad ground on the high beam side. The ground may be enough to handle it at idle but when it gets more juice it'll pops b/c the ground isnt good enough. I believe i've read a few times about ppl having problems with their headlights and it was the switch itself on the left handbar being the problem. Do a search to get some more info and read up on other problems ppl have had before you go ripping things apart to fix the problem.

If you have access to a multimeter, test your connections (look for spiking over 13v)
