Hi All, Not very mechanical, but I think I have the right name of the parts. Got my 2015 used and P.O. had installed Oxford Heated Grips. Occassionally the grip would slip on the throttle tube. Not a big deal until now it slips more easily and eventually the cable from the heated grip can't rotate any more. It appears the grip was not pushed far enough on the throttle tube and/or the end spikes were not ground down. No matter, everything works fine if I can stop the slipping of the grip on the throttle tube. Any simple ideas of what to add in the space by the spiked plastic piece to adhere the two together? Any kind of adhesive for rubber to plastic? Would prefer not removing grip.
