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.
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.
