Welcome!
We have beat the starting problem to death many times and everyone has their own special trick! I would first try the Search at the top of the page under the KX Riders Logo!
As for how I start mine, turn on gas, choke on, lean bike over till you see gas running out over flow and the kick it like you really mean it, with no throttle or just a crack!
Also some say a reed spacer helps anyway it did on mine!
Good Luck!
Alan
