look men it's just sooo easy...
just go to an object like simply A WALL
then just right before you hit it go a bit to the left and then tap enter till you get back on the bike...
well i started practising with faggio's so that's what i recomend practise at the police station in vice city with the graas bump right before you hit it keep on tapping enter/exit
you should do a backflip and get on when you think you got it try it on a car when you think you can do that try it on real motorcicles...
that's how i did it and now i can do it just everytime even when i go super fast and i do a jump with a distance of three-hundred feet and i go onto a wall i can do it...
did it once but still...
anyways read it very good what i tell you and good luck!
