200x bore question

[brandosfiero]

not to be post to much but i was looking at my cylinder and the piston looked a little bigger than i thoght they were .i measured the the bore and and its 90mm i thought stock was 63mm.can some tell me whats going on.i put a picture in to so you can see it

If it's got a 90mm bore, then it's not a 200x motor. That would make it a 381.7cc motor and I'm not buying that someone doubled the displacement of a 200x motor.

That doesn't look like a 200X cylinder to me.
