That's exactly how it's meant to work. Full on for starting the engine, then let it fall back to the first notch , this is the riding off position.
Then off completely when the engine is warm enough.
I'm amazed by the amount of people who rev the engine with quick aggresive twists of the grip when it's cold, a big twin cylinder bike with a slow idle will stall -
My loan bike (1150R) is a good case in point, it's set up for a slow idle when hot, i have to explain and calm people down as they try and rev the bollox on and off with the engine cold and wonder why it stalls on them.
Only a very small percentage manage to ride off without any fuss, generally those who are mechanically sympathetic and smooth riders.
And don't mention 1200 riders/owners who have forgotten all about fast idles and chokes.......
