For those considering this, YES it's possible to put a TM on the 2010/11 with the heated grips. Bit of a PITA, but do-able.
After rolling back the outer grip, you're presented with the inner grip that contains the grip heater wires. It's stiff and doesn't want to roll up. Using all 10 of my thumbs, I managed to get about a half-inch of the heated portion rolled up (the imbedded wires make it stiff). Be careful you don't eff up the heating wires.
I put the bushing up against this and using the square end of my T-handle allen wrench, pushed the bushing the rest of the way under the heated portion. Unrolled everything and did a trial run with all the shims. Nope. No engagement at all.
I ended up with just 3 shims out of 5 and it works fine.
Will take some photos and post them later. NOW I'm going for a ride
