Mikuni Main Jet Large Hex Carburetor

The Mikuni Large Hex Main Jet is a carburetor metering jet (also called a main jet or carb jet) that controls how much fuel flows through the carburetor at mid-to-high throttle. Changing the main jet is one of the most common ways to fine-tune fuel mixture. It lets you adjust for engine modifications, intake and exhaust changes, altitude, and temperature.

• Large hex body design for easy installation and removal with a standard socket or wrench
• Precision-calibrated metering orifice for consistent fuel delivery
• Made by Mikuni, a long-established maker of carburetors for motorcycles, ATVs, snowmobiles, marine and other powersports applications
