yep..get a hold of myron at Zuks offroad.
the harley carbs dont flood out like the webbers do. the toyota carb is old school zuk tech...
i seen one of these setups in person and it definitely let the engine rev quicker and the owner loves it. personally i gave up on carbs and am sticking with EFI. an EFI zuk WILL run upside down. personal experience here on that one lol
