Keihin 112 Main Universal JetRef : IH00139A / 1106195

The KEIHIN 112 main jet is a replacement part designed for carburetors equipped with interchangeable jets. Designed by the Japanese specialist KEIHIN, this jet allows for fine-tuning the air/fuel mixture at the main circuit, an essential step for achieving clean carburation and a smooth engine response at full throttle.

• Usage: carburation adjustment, optimization of throttle response, correction of mixture during modifications (exhaust, air filter).
• Compatibility: designed for KEIHIN carburetors and vehicles equipped with standard format jets (check the diameter and reference on your carb before replacement).
• Manufacturer reference: 99101-357-1120

The marking "112" indicates the size of the jet: replace it only if you check the carburation or follow an adjustment procedure. Installation requires disassembling the carburetor, thorough cleaning of the fuel circuit, and road tests to validate the adjustment. Plan for idle and acceleration tests to safely fine-tune the configuration.

Biker tips: handle this small component with care (risk of loss), use appropriate tools, and note your original configuration before any modifications. If in doubt, entrust the adjustment to a specialized workshop.
