Another thing I forgot to mention; when I take out my 201K (belt driven motor) I some times have to run it a bit before the belt grips optimally. It doesn't happen all the time, but it now and then I have noticed it. Maybe it just needs a bit of warm up if it's cold. I think it was ArchaicArcane who compared it to car tires, they need to turn a bit to get optimal grip too.
