Pushing throttle all the way forward is possibly choke, used just for starting purposes, also before shutting down let engine idle for 30 seconds.

thank you for the link it helped a lot but as far as the throttle issue yes letting it idle for 30 seconds stopped the backfiring but with the throttle as shown in the picture it shows full throttle at the top but you may be right it could be a choke symbol but i am not sure this is my first rider and im still figuring some of the things out, that is why i am uploading an image..

All the way up is the choke position used for cold start. About 3/4 of the way up there is a V notch which is the full throttle run position.
