Needle Jet R-8 for KTM, Husqvarna & GasGas 125-300 2017-2023 - 55431021000

This OEM Needle Jet R-8 is a critical component of the carburetor's fuel metering system. It works in conjunction with the jet needle to control the air-fuel mixture during mid-range throttle openings, ensuring smooth engine performance and optimal power delivery.

This part is compatible with a wide range of 2-stroke models from 2017 to 2023. It fits KTM 125 SX/XC/XC-W, 150 SX/XC-W, 250 SX/XC/XC-W/EXC, and 300 XC/XC-W/EXC. It also fits Husqvarna TC 125/250, TE 150/250/300, TX 125/300, and GasGas MC 125/250 models.

Precision-engineered from high-quality brass, this genuine spare part offers the exact tolerances required for consistent jetting. Replacing a worn needle jet can resolve issues with bogging or inconsistent throttle response caused by internal wear or debris buildup.

When installing, ensure the carburetor body is clean and the jet is seated correctly. It is recommended to inspect the jet needle for wear at the same time to maintain perfect synchronization within the carburetor assembly.
