This Keihin Main Jet 178 is a genuine OEM component designed for precise fuel metering in your motorcycle's carburetor. It plays a critical role in managing the air-fuel mixture at high throttle openings, ensuring optimal engine performance and preventing lean or rich conditions during operation.
This part is compatible with an extensive range of motorcycles, including KTM 125, 150, 200, 250, 300, 380, 400, 450, 520, 525, 530, 625, 640, and 660 models from 1997 to 2016.

Manufactured from high-quality brass, this jet offers excellent corrosion resistance and dimensional stability. Using genuine Keihin parts ensures that your jetting remains consistent, which is vital for maintaining smooth power delivery and engine longevity across different altitudes and temperatures.
Replacing a main jet is a standard maintenance task when tuning your carburetor for specific riding conditions or exhaust modifications. We recommend verifying your current jetting setup before installation to ensure this 178 size matches your specific tuning requirements.
