I had it happen to me too. Downshifting to a stop the OEM linkage would lock up and I had to temporarily up shift to get unstuck. This occurred a dozen times between 35,000 and 45,000 miles. Now at 60,000 miles it doesn't seem to ever happen again. I am certain there was an 'edge' on the shifting fork that has found it's happy place.
Love this Bike!
