Mikuni HSR 48-2 Carburettor
HSR48 Details and Applications
Mikuni’s HSR48 is a special version of the proven HSR42 carburettor. Its purpose is to provide maximum airflow for the most demanding high performance engines.
The amount of power any engine can deliver is directly related to the volume of air it can use in a given time together with its efficiency in using that air. Everything else being equal, more air equals more power.
Leaving port and combustion chamber design aside, air flow through an engine can be enhanced or limited by anything it must pass through. A restrictive air cleaner assembly, too small carburettor, restrictive intake manifold and a restrictive or poorly designed exhaust system can (each or all) limit power output. The HSR48 was developed to deliver additional air flow to highly developed engines.
