Motorcycle Carburetors  

Mikuni & Edlebrock:

Mikuni CarbsWhen it comes to fuel induction systems Mikuni has taken the scientific approach towards making more power. Some aftermarket motorcycle carburetors use butterfly throttle valves which obstruct the carburetors venturi at all throttle openings creating airflow turbulence and hindering precise air/fuel metering. The Mikuni HSR with its flat throttle slide allows for an unobstructed venturi that actually flows more air at full throttle to produce more peak power than other carburetors with bigger bores. While at smaller throttle openings the Mikunis' smaller yet higher velocity flowing venturi, together with its advanced fuel metering system provides a stronger overall powerband. Features greater (15%) air flow, enlarged needle and float bowl, adjustable accelerator pump, and enrichner system. All kits are jetted perfectly and ready to run. Included is complete installation instructions and owner's manual. Not for use with nitrous oxide systems. Will fit cruise control model bikes if cruise control is not used.

Intake adapter for HSR Carburetor to S&S manifold.

Intake adapter shown installed.

INTAKE ADAPTERS FOR HSR CARBURETOR TO AN S&S MANIFOLD

If you are trying to install a Mikuni HSR-42 or 48 carburetor on your big inch motor that no longer has the standard length cylinder/head combination, these carburetor to manifold adapters will help to solve your problem. Simply use an S&S brand intake manifold that is designed for your specific combined cylinder and head length. This CNC machined billet aluminum adapter will fit perfectly between the S&S manifold and the Mikuni carburetor. The tapered bore of the adapter will perfectly match the carburetor to the larger plenum of the intake manifold providing a substantial flow increase.
