I use aerosol silicone on all my K75/K100 throttle tube gears. They not only twist much more easily but they also return much faster.
If you don't have heated grips then pulling the throttle tube off and doing the handlebar with silicone also helps.
If'n you're Type A you can pull the perch apart and clean out all of the 30 year old way too thick dried out grease that came from the factory but even if you don't the silicone will still make a world of difference. I used to get out the old grease but don't even bother now when rehabbing an old K. I just spray the gears down with silicone and all is good.
You should also be sure that the grip rubber is not rubbing against the perch or, if you have it, a bar end.
