I find on my new 650r that when i turn the bars hard left the throttle jams open. Not wide open but definately does not return. Seems these cables are too short as i have oiled every moving part possible. Its pretty hard trying to do donuts when the throttle sticks open. Mind you its pretty hard on this bike anyway because of the way it delivers its power. I lean the bike over and boot it and the bike does a half circle and then takes off in a straight line with me hanging on like a rag doll starring at the heavens. Sound familia? Anyway i dont know if i can ajust the cables without having slack in the action which i don't like.
