Mikuni Throttle Slide Cutaway Brass Left-Hand Idle

Mikuni brass throttle slides (also called throttle valves or carburetor slides) are genuine replacement and tuning parts for Mikuni round slide carburetors. Each one has the idle adjustment screw on the left side. They give you a simple way to fine-tune your carburetor's air/fuel mixture.

Key Features:

• Genuine Mikuni part: Made in Japan for Mikuni VM-series round slide carburetors.
• Brass construction: Chrome-plated brass for durability and smooth movement in the carburetor bore.
• Left-hand idle design: Handed for carburetors with the idle adjustment screw on the left side. Mikuni slides are handed by idle screw location, so check that it matches your carburetor.
• Tunable cutaway: The cutaway shapes the air/fuel mixture from just off idle through about the first half of throttle travel. It has the most effect between roughly 1/8 and 1/4 throttle.

Tuning Benefits:

• A smaller cutaway number gives a richer mixture.
• A larger cutaway number lets in more air and gives a leaner mixture.
• Changing the slide is a common way to correct throttle response and mid-range mixture after changing the exhaust, intake or jetting.

Use genuine Mikuni jets and parts with these slides for best results. Select the correct series and cutaway for your carburetor from the options above.
