You could try different grip material.
Also, try Ivan's method for adjusting the TPS.
Warm the motor to operating temp and pre-loosen the Torx screws on the TPS.
Next, set the rpm to 3,800 by winding up the idle adjuster. Slacken the TPS screws and rotate the unit in either direction looking for the highest achievable rpm. You should be able to get an increase of 200 rpm or more. A final reading of 4,200rpm is not unusual.
What you're doing is finding the ignition timing sweet spot for part-throttle cruise. Once you've found it, tighten the TPS screws, reduce the idle back to 1,250 - 1,300rpm and then go round to apologise to the neighbours.
