I've got a KLR 650 made in 2004. In the 4 months I've owned the bike it has gone through 2 head light globes, which I think is a few too many. Anyway here are the symptoms of whats happening: 1. Sometimes when the bike is switched to the on position the headlight doesn't come on, however, once the indicator is flicked on and off the headlight will turn on. This also happened when I replaced the blub. 2. High beam is really weak it seems much worse than the normal low beam. 3. When the bike is on high beam and it is idling it seems to light up the road just fine, but when the bike is revved it starts to pulse between dim and very dim. I think this may be a vibration thing and not a charging issue because this doesn't happen to any of the other lights on the bike. I have checked the head light connectors and they seem clean, there is no corrosion on them. When I replaced the bulbs I was very careful not to touch the glass on the bulb. What can I check to get to the bottom of this issue?
