Definetaly dont give it gas in the air unless you feel like riding like a goon. Sometimes you can do it to lift your front tire up. jump higher by seat bouncing. (pulling down on the right stick before take-off) discovery points are flags that you must ride up to on maps. 2 stroke 4 stroke can be defined by the telltale sound and pipe. 2 strokes have a huge metal pipe at the front and a smaller mufler, and sound like a bunch of pissed off bees or something. 4 strokes have a large muffler, and have a much lower sound.
