Riva Fuel Return Line Restrictor 1/4″
The RIVA fuel return line restrictor installs into the fuel return line between the carburetor and fuel tank, restricting fuel return rate, and increasing the carburetor’s pressure. This improves throttle response and reduces lean conditions in the power band.
This precision-machined billet restrictor accepts Mikuni Main Jets (not included) to match your application. For use with OEM and aftermarket carburetors.
