HSR SMOOTHBORE CARBURETOR KIT FOR BIG TWIN

Weight: 3.65

• When it comes to fuel induction systems Mikuni has taken the scientific approach towards making more power.
• Some aftermarket carburetors use butterfly throttle valves which obstruct the carburetor's 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 Mikuni's 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.
• Will fit cruise control model bikes if cruise control is not used.
• 48 mm Full Race Carburetor Kit is designed for 100+ ci engines.
• Includes adapter for a two-bolt S&S Super G type intake manifold.
• Requires Big Twin 1990/1995 throttle cables found in the Control section.
• If mounting on a Big Twin Evolution 1993/Later, we recommend using our 82438 head breather vent/air filter mounting kit.
• If mounting on a Twin Cam, we recommend using our 82435 mounting kit. These kits can be found in the Fuel section.
• For maximum filtration, use our 84584 K&N® brand air filter element. This element is designed to be used with a Big Twin Evolution 8" round filter cover.
• If using a custom flat backed air filter with a 3 bolt mount, use our 82882 adapter kit found in the Fuel section.
