    Throttle cut at 20+ degree rotation
    « on: 2018-07-04 01:59:04 »
    2013 gtl cuts off throttle at approx 20 degree rotation of the throttle grip. One iota more and it’s like fuel or spark  is chopped. Very consistent at same throttle position. The bike otherwise runs smooth, and will do 100mph in 6th given enough time. Kind of frustrating to have all that torque and only being able to get to 25% of it. I do have a service due light (time) and an engine fault light. Bike had sat for close to a year. Battery was dead. Installed new battery. And it fired right up. But after about a minute sputtered a bit and died. I suspect bad fuel, siphoned out the old and filled w/ premium and half a bottle of gum out. Started back up, sputtering went away, but ever since throttle cut out at precisely the same spot. Ran a whole tank of fuel through it, and it runs smooth - but w/o all the monster torque. Any ideas?

      Welcome to the forum.
      Do you still have the engine fault light?
      Depending on the severity the bike may go in 'limp mode' reducing throttle,torque, etc.
      Better have your dealer check it out.

        Thanks for the welcome Frank.
        Yup, still have the light. Need to get appointment scheduled.
        Was hoping somebody had seen similar problem and had a quick remedy or "was fixed by part X" - anything other than a dealer visit.
        Drop off logistics always a hassle. :(

          could be dirty air filter? fuel filter?  bad gas?

            sounds like bad fuel pump

              2013 with a bad fuel pump would be disappointing as far as quality control goes .  I bet the GS911 would pick up the error.  I have heard of injectors going bad on 2011 and 2012.  The 911 would pick that error up for sure

                Mystery solved. Dealer diagnosed to a bad fuel pump. Service manager said ethanol eats into the pump in some way and he is having problem with BMW covering even for nearly new models. BMW advise not letting the bike sit for more than a couple weeks w/o running. [/size]All the giddy-up is back. [/size]Took the bike out w/ my band of hooligan riding buddies and terrorized all manner of vehicles, bicycles in the Santa Cruz mountains. I guess I need to spend less time on the S1000R and Multistrada and a bit more quality time w/ the Bavarian heavy bomber going forward.[/size]
