Short version:
The bike misses every once and a while when riding and keeps burning out bulbs. The miss seems to be at constant throttle any RPM. I did some maintenance Saturday then washed the bike. It ran the worst it has so far and burnt out a bulb within 2 minutes. Running voltage at the headlight seems to be 14.3-14.5 per a HF multimeter.
What can burn out a headlight bulb? Any common areas of the harness I should check first? My battery voltage is 12.6-12.8 with bike off and 14.3-14.7 running at any RPM. Due to these voltages, I haven't suspected the charging system.
Long Version:
Bought a Buell a month ago. Clutch needle bearing failed, clutch didn't work. That has been fixed and seems to be holding up. On to Isssue #2. The PO said it burned out low beam bulbs so he only ran high beam. I sized it up as a bad low beam connection. I think I was wrong as it burns out bulbs in either socket and at a very high rate. Yes, I'm installing without touching the glass. I wear gloves and make sure the glass doesn't touch anything including the gloves or housing when installing.
The bike burned out 1 low beam and 2 high beams in less than a few hundred miles. Its hard to know when during the ride that the bulbs burn out, but it seems to always be on a trip when the bike has a "missing or coughing fit". I removed and cleaned old metal shavings from the stator/rotor yesterday. My neutral light has been intermittent so I cleaned the sensor. I then rode around with the pulley cover off and cluster cover off with a multimeter hooked to the headlight socket. Ran lots of errands and the bike ran well. Voltage was between 14.3-14.5 running at all times and 0v with the headlight switched off. Maybe an few subtle back fires on deccel and possibly at constant throttle, but nothing bad. The whole day goes by and nothing.
I then change the engine oil, clean throttle body, put the pulley and gauge covers back on, wash it and it runs like poo. It was bad enough I didn't drive it but pulled it in the garage. At any constant RPM it would obviously break up. My idle is usually around 1100. At this point it would surge down to 600-700. Also my headlight bulb burnt out during this fit. I threw the multimeter on that socket and read 14.3 switched on and roughly 11V with the headlight switched off. This "off" setting previously read 0v. During this missing fit, I wiggled on the harness around the drive pulley area with no noticeable changes.
I hadn't suspected the charging system before due to the strong Voltage output, but I also don't know what will burn out a headlight bulb? What will burn out a headlight bulb so far - I figure over voltage is the only way? Any suggestions where to start? Any common areas I should check on the harness?
The weather is beautiful. This forum seems like a great place, but on this beautiful morning I'd rather be riding than typing.
