So I got my B3 back from the dealer last wednesday (sprag and coolant fixes) and I've ridden it basically every day since then. I went out on a ride today that lasted probably 100 miles. I stopped at the house of one of the guys I was riding with and when I came out to start the bike I turned the key on, all the lights came on, the fuel pump primed but when I went to start the bike everything went blank. I tried undoing the key and trying again and it wouldnt even turn the dash or lights on. Checked the fuses and all was well. Popped the tank off and the battery showed 11.5V which is a little low. Tried jumping the bike and while the dash and everything would turn on it wouldnt even try to turn over. Now lets assume that the battery is dead. There is clearly a problem that led to a bike having a dead battery after riding for 100 miles and sitting, with the key out, for maybe 20 minutes.
