The wobble is what is known as a tank slapper. All you can do for those
is either A. get a steering dampner and B. hang on for your life. It's
caused in wheelies is by the front tire not landing inline with the
rear.
As for shifting i've got no clue i don't stunt, but if i remember right
most people don't shift from 1-2 while in wheelies, it's normaly 2-3 or
higher.
