Mikuni Large Round Main Jets are precision-machined carburetor main jets for tuning fuel delivery in Mikuni round-slide carburetors. Also called main jets or carb jets, they meter fuel at mid-to-high throttle and have the biggest effect on wide-open performance.

Key Features:

• Large round body design made for compatible Mikuni carburetors
• Available in a range of jet sizes so you can tune for jetting changes caused by altitude, temperature, exhaust, intake or engine modifications
• Threaded design for quick installation and removal during tuning
• Made by Mikuni, a long-time name in carburetors for motorcycles, ATVs, snowmobiles, marine and other powersports use

Choosing the correct main jet helps with throttle response, power delivery and air/fuel mixture. Select the size that suits your carburetor and setup.
