Welcome. Find a big parking lot and practice there. Stalling is usually caused by a lack of coordination between the throttle and the clutch. Both require a decent sense of feel to operate properly, and that feel can vary from bike to bike. It shouldn't take very long to learn. While you are practicing that, also practice braking. You need to reach the point where you can hold the wheels on the verge of lockup without actually locking them.
