My bike appears to have more or less identical grips on either side except for the extension that pulls the throttle cable. The right side, of course, is free to rotate and the left is glued on. Both sides are identical in construction except as mentioned. I need a fool proof method of dissolving the glue without ruining the grip. Suzuki sells them as assemblies with the rubber already installed.
I want to fit bar/end mirrors by sliding the grip part in about 1/2" on either side. Then clamping the fitting over the bars.
If they are stock grips then they look identical on the outside, however the right grip will have a larger internal diameter to accommodate the plastic throttle tube. Most aftermarket grips also have different IDs.
WD40 works well to dissolve the glue on the left one. As for the right one (if I remember correctly), if you take the end cap off, and loosen the bar-clamps on the control box, the throttle tube can slide in further.
However, on the stock bars, there is a locating pin cast into the inside of the control boxes. They seat into hole in the handlebar. I, and others here, have ground off that locating pin, allowing freedom of placement along the bar. I've had no problems with the box clamping on tight enough. Others have also reported no problem with this little 'mod'.
