Keihin Idle Jet 48 for KTM 85-300 SX/EXC & Husqvarna 1994-2026 - 54531607048

This genuine Keihin Idle Jet 48 is an essential OEM component designed for precise fuel delivery at low RPMs and idle speeds. It ensures a smooth, consistent idle and crisp throttle response by accurately regulating the air-fuel mixture during the initial stages of acceleration. As an original equipment manufacturer part, it guarantees perfect fitment and reliable performance within your carburetor assembly.

This part fits an extensive range of models, including the KTM 85 SX, 125 SX/EXC, 150 SX/XC, 200 EXC/XC-W, 250 SX/EXC/XC, and 300 EXC/XC/XC-W from 1994 to 2026. It is also compatible with Husqvarna TC 85, TC 125, TC 250, TE 125, TE 250, and TE 300 models, as well as GasGas MC 85 17/14 and 19/16 versions. Additionally, it fits specialized models like the KTM Freeride 250 R and various Rally Factory Replica machines.

Precision-engineered from high-quality brass, this idle jet is designed to resist corrosion and withstand the harsh environment inside a carburetor. Replacing a clogged or worn idle jet is critical for solving starting issues, erratic idling, or "bogging" at low throttle openings. Using OEM Keihin jets ensures that your engine's jetting remains consistent with factory specifications for optimal power delivery.

Installation typically requires basic tools and access to the carburetor float bowl. We recommend cleaning the carburetor thoroughly before installing new jets to prevent debris from obstructing the small orifices. Regular inspection of your jetting is advised when riding in significantly different altitudes or temperatures to maintain peak engine health.
