Popping up a basic wheelie is not so tuff but carrying it to a longer distance is hard.
To pop up a wheelie reach a speed of 10 to 15 Kmph.
Slowly tap the rear brake so that the front forks can go down(action) simultaneously release the clutch rapidly when the throttle is 50%.This will lift the front wheel.
After popping up bring the bike at an angle of 60 to 70 degree to do a safe stretch by maintaining the angle. If the bike leans backward slowly tap the rear brake. If the bike leans frontward raise the throttle a little bit by following this method you can pop up a basic wheelie. With regular practice you can also shift the gear on a wheelie it will make you master the basic wheelie.
