Just left the Yammi dealer, the guys in parts were showing me this slip in thing-that goe's between the air box and the carb . Sort of a venturi, that's supposed to make some more HP. Anybody know what this thing is, or how it works? Reviews???

Not pedaling, just curious.

Yeah, the dude behind the counter at the Yammi dealership-told me someone he knows put one in and slipped on a pipe-9 hp gain. Maybe just CACA, I think I'll wait for more test's, before I plop down the C-note.
