OK then, downloaded and tried it.
I understand you are very young and have probably tried very hard so I'll be as constructive as possible

There isn't really enough to be a game - Pcar on the track creator, you can't lose, you drive around till the AI cars fall off the map, if you fall off the map you just keep falling - no endings.
The bike models are taken from Fourdee's TR-Zero game and credited to your team (everyone knows Fourdee's work well here)
There are a lot of other models in the folders but they don't appear to be used for anything.

so either use your own models or credit the creator, try to make endings for the game - ie won and lost, play with the Pcar settings - the ones you used don't suit motorbike handling

Robert,Just see my game's trailer.I have published it before weeks.Many of them have seen the trailer.Just see the old topics.You can see Interon Chicago as a  subject.This is the link.http://www.youtube.com/watch?v=XwWfgk-KZ9M

WOW! What an evidence of this copy! 

I doubt it as he already ripped Fourdee's models for his first "game" and no credit went to Dan

ooks like mike caught you. i downloaded both the models (splatter g's model and man dun's model) in mandun's model i exported it as skin mesh, and compressed it with winrar  and came to this conclusion that both these models were the same (99.9%) as there was hardly any difference between the sizes of the compressed files and there is hardly any difference between the screenshots. so according to my investigation both of these models are the same.hence proved.

so this is how you're gonna start out... stealin' other people's stuff and puttin' your name on it...

looks like there are more detectives than developers on this forum
the scenario of it can be explained in these 2 images
the first image shows how splatter g explains it.
and the second one shows our plain and simple message
