A system designed to precisely meter and deliver fuel into the combustion chamber of a 125 cubic centimeter engine replaces the carburetor. This retrofit offers enhanced control over the air-fuel mixture, leading to improvements in engine performance and efficiency. Examples include aftermarket kits containing the fuel injector, electronic control unit (ECU), wiring harness, and associated sensors.
The implementation of this technology on smaller displacement engines provides several advantages. These include improved fuel economy, reduced emissions output, and more consistent engine operation across varying environmental conditions. Historically, carburetors were the standard for fuel delivery; however, electronic fuel injection systems offer greater precision and adaptability, contributing to a more refined riding or operational experience. The development of compact and cost-effective systems has made this technology increasingly accessible for 125cc engines.
