last weekend at Daytona, stuck in traffic, blazing hot. Knucklehead in front of me drift over into my lane, I hit the horn button and it sounds like an anemic moped with a sinus infection. seriously lame. to make it worse the guy heard it, turned around and laughed. I know the bike was hot and I know when I had this issue with my 06 road king, it turned out to be my regulator was failing. Could I be having a regulator issue? or could this just be that everything on the bike was hot and i shuoldn't worry about it?
