A nice 70 degree day (rarity here) so me an my buddy got back from a mini road trip, i was riding all friday night, even through the fog at 3 am then i left it out overnight. The next day we put it in my buddies apartment and leave it all day. So then this morning i bring it out and it just kicks over and dies. Tried again nothing, gave it a second then tried the starter for like 10 seconds and it just wouldn't turn over. Repeated that about 3 times waiting about a minute each time and no go. Finally we were yanking the gas and trying to start it and it kicked over and smoked pretty bad out the pipe. Waited a m minute, tried again and got it to idle. Then i let it run for aabout 45 seconds and tried giving it some gas. It went up to 5k and died. WTF!! So then i started once more and let it idle for a minute then its been fine since. Any ideas what would have caused that?
