The other thing worth mentioning is is to get the feel of the kick start lever hitting the throttle stop.
If you kick all the way through to the stop & HOLD THE LEVER THERE then the bike can not kick back.
Most people only kick the lever till it is vertical down but to get to the stop it has to go a tiny bit forward.
This is very difficult to do if the bike on on either stand but easy to do if you are standing next to the bike .
A lot depends upon your actual body shape and leg length so no actual starting proceedure is absolute gospel for every owner
What is important is the position of the piston at the end of YOUR kick, it has to be just past TDC or you risk a kick back if the lever is not hard against the stop .
Thus depending upon your physicue the starting position may vary somewhat
As Dave has mentioned, Listen to your engine for wheezes from the carb & exhaust so in a short ampunt of time you will recognize when the bike is telling you to start your kick
After that you will develope the muscle memory in your leg to know when to stop turning the engine over & when to start your kick.
And remember it is a KICK starter not a Leap on from a great hight starter .
just for fun a link to Doug Frasers video showing him starting his gold star by hand so you don't need to leap like I see way too many owners doing .Doug starts his bikes
