... I had an issue a few months ago where it was difficult to select neutral when coming to a stop ie it would hop from 1st to 2nd then back to 1st etc.It needed surgical precision to hit the spot.
The problem was the clutch needed adjusting.Over time the cable stretches a bit and you end up with too much freeplay at the lever and the clutch doesnt disengage properly.
I adjusted it up and all was sweet again.Worth a try.
