RIVA Fuel Line Return Restrictor

Designed to improve throttle response and reduce lean conditions in power band, our Fuel Line Return Restrictor installs into fuel return line between carburetors and fuel tank, restricting fuel return rate, increasing pressure to carburetors. Precision-machined billet restrictor is threaded to accept a Mikuni Main Jet (not included) to match your application. For use with OEM and aftermarket carburetors using 1/4" fuel line.
