This is just offered up as an FYI and so you guys can check your own bikes...
Got a new rear Tourance EXP mounted yesterday - after getting a wonderful 5,800 miles out of the original I should note - and on the way home from the dealer I pulled up at a traffic light and noticed my bike's reflection in the tailgate of the Suburban in front of me... But unfortunately the reflection showed my right-side headlamp was out. "No problem" I thought, "Just a burnt out H-7 bulb, and I got some of those at home." Reason I had some spares at home, you might ask? Well, the right-side bulb is the one that burnt out on me during my trip home from Alabama.
Anyway, got home, pulled the round cover from behind the right-side headlamp bulb and went to pull the headlamp plug... And low and behold, the plug sort of comes apart in my hand, obviously badly damaged by too much heat. It's then I also notice that the light-blue wire is also scorched, with even some of the insulation cooked completely away. I pulled the bulb and oddly enough it looked fine. I also pulled the left-side headlamp bulb cover, plug, and bulb... Everything on the left-side looked fine, and I even swapped the bulbs back and forth, and both bulbs were 100% functional. The headlamp beam shutters work fine on both sides, as do both the marker lamps adjacent to the headlamps. Only real worry to me is that even the left-side headlamp plug and harness seems to run awfully hot, and this is with plain, ol', stock 55-watt Phillips bulbs... And when I say hot, I mean *HOT*!
The leads and plug are not very hot initially, but within a minute or two the headlamp bulb plug and wiring get plenty toasty...
You might want to check yours.
I contacted my dealer, and he is placing a call to Yamaha to check if there have been any other reports of similar problems. He also wants me to bring it in ASAP so they can check out the rest of the electrics and get me a new headlamp harness.
I should add I have checked everything I can externally, and there is no evidence of any problems elsewhere, and the switches, fuse box, etc. are all fine and appear to be operating cool and at design temperatures. It just seems to be that final headlamp harness is where the problem lies, but we'll see, and I'll update this thread as I have more info.
Meantime, I would recommend that you check your headlamp harness, plugs, etc. and their operating temp. I would also recommend sticking with stock wattage bulbs if you have a choice...
Again, this is just an FYI.
