Theres all my tips for you, but the most important really is a practice and starting with normal grinds from wheelie.
1. Your motorcycles bottom must hit the grind just the right.
2. After you hit the grind right, you must find the balance, if you lean to the other side too much you fall out from grind.
3.Practice it on easy spots.
Krail also helps to land a grind if you got a good bump or hill
Looks nice too.
Ask something if you want.
