Screw the tutorials, just fiddle with it until its done, there is no surefire way to get a trick done with those mods, unless you wanna replicate a replay 1 by 1, which is lame...
Edit: oh, this ain't toribash related....uh....try some more anyway. Maybe start with a shove it first, might be easier for a starters trick. ( took me 2 years to learn how to kickflip and now its my fav...) Sometimes it just takes some time.
