I want it!!!
I am just unwilling to mess with the grips. Too afraid I will ruin it.
It's really not a problem. Just get a long thin piece of metal and some WD40. Take your time and work it between the rubber and the throttle tube. In a few minutes the grip will be off. I use silicon goop to glue it back on to the new tube. I put it inside the grip, not the outside of the tube. That way none ends up inside the assembly to gum it up. Then remove any excess at the end before reinstalling the end weight. Seriously, I spent about 20 min installing it.
