Highly developed engines use fuel more efficiently, but not if they're poorly tuned. Mikuni pilot jets are one piece of your tuning puzzle. Pilot jets are replaceable and the pilot air screw is adjustable. If the jet is too large or the air screw is in too far, then the air/fuel mixture may be too rich. That's one reason why Mikuni pilot jets come in different sizes. The brass pilot jets will deliver a precise amount of fuel so you can have your machine running perfectly. Don't waste time trying to do the impossible--replace your pilot jets and start having fun.

They act as fine-tuning components in regulating the fuel to air mixture. Additionally, the proper working of your Mikuni air jets is especially important when a bleed-type needle jet is utilized. Mikuni air jets are made of brass and come in different sizes to help get your machine running like a top.

Mikuni 8 Series carburetor needles are high-precision and calibrated for an extremely accurate fuel flow rate. Designed to suit the Mikuni HSR Carbs, these jet needles are also suitable for Harley-Davidson® and other motorcycle applications. The jet needles are the tapered rods that are positioned in the throttle valve by the 'E'-Clip. The taper of the needle increases the clearance between the jet needle and the fixed needle jet outlet as the throttle is opened. As the air flow volume increases past the throttle slide, the fuel volume is also increased to maintain the correct air/fuel ratio. The Mikuni 8 Series jet needles are manufactured from brass to offer long and reliable service to help improve the performance of your motorcycle or ATV, keeping your ride running in peak condition.
