Well, according to Novarossi's exploded views that is correct. I can also comment that the internal parts that changed were the crankshaft and the conrod. The external parts that changed were the body of the carburetor, the head, and the crankcase.

The difference between old and new parts, I am not aware of. Im just stating the parts that got their part #'s changed in the exploded view of the 353 '09.
