So i come home today from work and pull the bike in the garage......put the kickstand down and the bike shuts off close the garage door and go inside....bout 15 mins later go in fridge in garage to get a coke and light on the bike are still on so i try to crank it and no dice.....what do i do now? will it recharge itself after sitting for a bit?

 

I'm pretty sure you'd have to put a battery charger on it or jump it from another vehicle.

 

Jump start, run it for a while and it will charge itself or battery charger works...

 

...your battery died from sitting with the lights on for 15 minutes?

 

alright.....yeah i got some jumper cables lying around somewhere....is it ok to jump it off a car battery???....sorry for being naive...just havent ever done this before...and yes...i was suprised from only like 15-20 minutes of sitting

 

just went into the garage and it cranked right up....i guess it just had to sit for a little while....thanks for the help guys

 

i doubt your headlights killed it after 15min. sure, the batteries are tiny as hell, but they should atleast last an hour or so.

 

push start? or open ur seat and jump it , although they don't recomend u jumping from a car. i did few times though nothing happen

 

you can't push start a fuel injected bike with a dead battery. If the battery drops below 12.5 volts, the injection system will not work forcing you to charge the battery.

 

usually if you can get the guages to register you can push start.

BTW: you said it fired right up after going back. When you first pulled in the garage you said you put the kickstand down and it shut the bike off meaning you were in gear. Now when you tried to start it it was still in gear and obviously would not juice the starter. Was that your problem?
