headlight not working? check the reason listed it might solve your problem
I just spent a few hours troubleshooting and fixing a friend's CBR F2. The headlight stopped working one day (low and high) and wouldn't come back on. Tested a bunch of things, obviously the bulb, and checking for continuity in various places with checking w/ the wiring diagram... finally traced the problem to a wire that had come off (solder broke off) in the THROTTLE housing. Wouldn't thought to have looked there, but apparently the headlight wires loop through the throttle housing since the headlights are turned off when cranking the starter.
I'm sure it's not a common problem especially on the RR's but if you're having trouble with your headlights on an older bike like the F2/F3/F4/F4i, you may want to check there.
