theres pretty much no way to tell. think about it, porting isnt unique, its just the process of precision material removal.

anyone could have done that porting. its got a pretty simple intake port with some boyeson boost ports. i think about all those things are good for is some low end. dont hear of too many people really doing them anymore except for passion. oh yea, the new cheetah cub cylinders have them..

it does not look like a passion porting at all though. almost even looks like someone did it themselves, looks like the right boost port goes into the cylinder sideall much farther than the left. Also it looks like someone went a little nuts with the dremel on the sides of the intakes. Whats that all about?

 

Is the exhaust port stock? it appears not to have anything done inthe picture but it is hard to tell.
