I bought a 2011 Road King. Yesterday I left my lights on and drained the battery. I was able to roll it down the hill and pop the clutch and start it. I rode it a short way home but its running funny at idle. When the bike's RPM settle (you know how the bike will idles just a tad slower after warm) it starts sounding like its missing or somethings tarding somewhere. When I give it some gas it sneezes out the pipe and runs fine, until the idle comes down and does the same thing again.

Could this be related to a low battery with all the electrical sensors on my bike?

 

I don't think so. Bike should run fine off of the alternator.

Disconnect the battery for awhile and reconnect and see what happens. After the battery is back up and fully charged.

 

Thanks... someone told me that it might be cuz the battery is not fully charged yet nad its affecting things?

 

buehler buehler anyone anyone

 

anything done to the bike as far as stage 1, 2, fuel management, etc?

 

It has a Stage 1 Race Tuner, and an Heavy Breather.

 

Try this, should work
- Use charger and fully charge the battery
- Remove the Main Fuse (or disconnect battery jumper) for 15 sec. then re-connect.

I would take a guess that at this point your battery is still low. From your description it turns out that you depleted the battery, then jup-started the vehicle, then left it idling for some time.

At Idle the charging current is very low, it barely exceeds the normal vehicle power consumption. At idle it would take hours for your battery to re-charge.

Another thing that happened when you depleted the battery is that the ignition controller lost the stored position of the idle throttle. Now it will take several miles of riding for the controller to learn and optimise the correct idle position.

 

+1 on the stored idle sensor position. I've had this happen and you will require doing 2 things to get it back to normal. pull the main fuse as Aborigen stated and then ride it for about 10 miles or so so that it can re-learn.
