trying to install an xb 9 primary on a friends bike (2007) i came across a strange thing:
if i'm not wrong stock xb12 primary front sprocket is a 35tooth one and an xb9 in a 34 toot, up on inspecting my friend bike his front sprocket is 38 tooth, any one know if this was some kind of mod on 2007 as he states that was stock no one changed it.
is there an option of a 37 tooth sprocket?

XB12 is 38 teeth
XB9 is 34 teeth
The sprocket on the left is the XB9 and the right one is a stock XB12.
