Mikuni VM 18mm round slide carburetor with clamp on mount.
Another very popular choice for 70cc kitted mopeds.
Screw on top gives easy access to the slide for needle adjustments. Large lever choke for easy choking.
Same size air filter mount as Dellorto PHBG (32mm). Will not accept a screw on air filter of course.
Intake clamp side is 23mm inner diameter.
Uses Mikuni Large Hex Jets as well as idle jets.
