    So my bike sat all winter, just purchased new battery and my bike is doing something it's never done before. When I start and idle the bike it's fine, but after a few min I try to give it throttle and roll off and it just fluctuates. The revs go up and then back down and teeters like that after ever rev. At one point it even stalled. Any help is appreciated.

    ...I should add that the revs go up and back down on its own after I roll off the throttle.

    Clean and calibrate the intake air control valve.

    Hello Joey. Did you do a re-set after putting in the new battery? Turn on ignition. Open throttle fully and hold a few seconds. Do this a few times. Then start up. Could be the problem. Rob.

    Rob,

    Where do you find this reset information?

    I think it is a carry over from a previous generation of BMWs. Adaptations on the F800s are performed with a diagnostic tool.

    Hello Joey. I learn the resetting from a similar experience to yourself. Bike was running really badly. Couldn't understand. Then read somewhere that whenever the battery is disconnected you have to do a reset. Very simple to do. Tells the throttle bodies the positioning of everything and allows the computer to respond to those settings. So: switch on ignition (but don't start engine). Turn the twist grip to it's widest opening. Hold for about 15 seconds. Release. Repeat a few tiimes. Switch off. Switch on and see if she fires up any better. Rob.

    Looking through both the F 800 GT Rider's Manual and Haynes Manual, there is no instruction of this reset. Also, there have been many messages on this forum regarding disconnecting or changing the battery without any mention of the need for this reset. One is left questioning the validity of this advice.

    Hello CCwatchmaker. I refer you to: https://f800riders.org/forum/showthr...throttle+reset

    And many more such like.

    Make up your own mind about the validity.

    I have replaced batteries several times on my 2009 F650GS over the years and have never bothered with any throttle adjustments afterward. The bike seemed to function just the same after the battery was removed for 30 minutes or so and the new one installed. However, I did have to reset the clock.

    Rob, Thank you for taking the time to clarify your earlier post. I am assuming that if there is an idling problem, performing this "reset" would cause no harm, although there does appear to be disagreement as to the necessity or helpfulness.

    Give it a try and let us know if it works for you.

    On both my 2003 f650gs thumper and my 2009 f650gs twin, if you make the reflexive mistake of twisting the throttle while starting (may be battery connection related as well..weak battery, etc), then the throttle position calibration gets messed up. Stalling when rolling off of the throttle is usually the symptom I get on the twin. The thumper does something more like you describe, and doesn't want to start back up.

    On one (can't remember which, but pretty sure it's the twin), just powering off and restarting without twisting the throttle will actually fix it (re-zeroing). On the other, the procedure has to be followed as outlined above.
    Also, no problems when I put the battery back in in the spring and just starts right up.

    Just my two data points from when I was a newbie on BMWs and learning not to twist at startup.
