    Can anyone help or has anyone had a similar problem with the following:-
    When I put my heated grips on (on my 2007 GS), after about 15 mins my throttle sticks and it won't spring back, can be quite dangerous if you miss your breaking point, especially the first time it happened.

    I have two options; take it into the dealer and get hammered with a bill. Or have a look at it myself and try not to mess-up anything. But before I do, I thought that I would ask for some help from some you knowledgeable nice gentlemen.

    Thanks very much in advance.

    Do you have any type of grip covers installed, i.e. Grip Puppy's or some other?. I had the same problem you did caused by grip covers I installed on my 12GS. The rubber covers I installed over the stock grips squeezed the grips and pushed out the ends a bit. Everything was fine without heated grips on, but after running them hot a while, it would soften the rubber and then the end of the throttle grip would rub the right hand bar end weight causing sticking. I had to add a thin washer to the screw that holds the bar end on, and that pushed out the bar end weight just a small amount and now no more rubbing.

    You need to move the entire grip assy back (to the center line of the bike).

    The grips expand slightly when heated and are rubbing, let me guess, on your throttle lock?

    Loosen the grip assy, and move it back on the bar 1/16 or less of an inch. That will give the grip room to expands when hot and not rub.

    No I don't have any kind of grip covers installed, everything on the bar is standard.

    JoshBMW has suggested something that I might try.

    Thank you both for the response.

    I'm not sure what you mean by throttle lock? Everything on the bars is standard, as per factory.
    Never-the-less your suggestion sounds logical and I shall give it a go.
    Many thanks.

    Moss,

    JoshBMW gave you the correct answer.




    I might be wrong... Just ask my X...

    If a man speaks, and there is no woman present,... Is he still wrong?

    Can someone clarify what Joshbmw solution is. Riding with a friend with new to him 2006 1200 gs with heated grips on and throttle stuck. Heated grips off and it was fine.
    Thanks in advance.

    The grips expand as they get hot... they get longer. That expansion causes the grip to stick as the ends rub. You need to give the grip more room. Moving the assembly that holds the grip, the brake lever, the mirror, etc., in toward the center of the bike will give the grip room to expand.

    This is usually exacerbated by the addition of a throttle lock at the outer end of the grip. As Moss found out it can happen to a stock grip, too.
