Hey Nilsey,
I'm in a similar situation. I was going to sync my carbs today, so I started my 400f up and let it idle a bit. Then shut it off to plug in the sync tool. I turned the key back on and absolutely nothing happened. No lights, no cough, nothing. Of course my cheapo multi meter crapped out as well, but thats another story.
Anyway, the bucket. I am going to try and build my own loom with molex style connectors instead of the bullets that come stock. You could try to "tidy" the headlight by installing some molex connectors to the stock harness I suppose, but I don't know how much tidier things would get in there. My two cents.
