Tuning Notes

Venturi size is one of the primary levers for matching PMO or Weber carburetors to a specific engine's displacement and cam profile — going too large can hurt off-idle response and too small can restrict top-end breathing. If you are not certain which venturi size your current jetting was built around, check your carburetor tag or reach out with your engine specs before ordering, since venturis are a precision fit item and are not typically returnable once installed.
