this one is alot easier than the diddy one.. not to mention u can get under final destination with it too

going from left to right heres how to do it...
1) face away from the ledge
2) hop off (doesnt matter how high) while facing the right
3) use ur bike for a good amount in the air
4) press a to do a bike jump
5) then jump one more time (at this point u should be in recovery range)
6) up b

ALSO if u have a fart, u can pretty much own the stage by landing in the middle

try it out
