not to thread jack but this does kinda go along with the discussion. ill keep it quick:
i picked up a yankee peddler with V1 which is super restricted. havent seen the ports or anything yet, but the 14.9 dellorto SHA and tiny intake manifold is a dead give away. the bike runs fine and as it should, just slow. ive only ever known the minarelli V1 to be a pretty quick little engine... anyone know what kind of restrictions they build in to make the slower models? just wanna know how far i can get with a carb swap and maybe a pipe.
