overrides scripts values in unityiphone multiplayer.

hello, i am working on a bike's racing game and in its multiplayer module. all is set but when i lean my bike from one phone the remote bike gets same values and it leans as well. it also try to move forward and take turns which causes jitter in my game.

My bike's hierarchy is.
Move and turn (bike moving and turing script).
Wheeling (bike wheeling script)
* bike tilt (bike tilting script)
- front tire
- back tire
- biker
- body

does anybody have any idea how to overcome this issue? Thanks in advance.
