Digital wideband air/fuel AFR meter from Koso.
Koso offers this air-fuel ratio meter with Bosch sensor for four-stroke engines, which allows you to find out the correct mixture for your scoot. The quick heating Bosch sensor establishes the air-fuel ratio, and warns you if your mixture is too lean or too rich.
A/F range = 10.0 - 24.0
Size = 100x42x23mm.
KOSO BA004066
Yes but the 2-stroke oil can damage the sensor over time so you wouldn't leave in there permanently.
The process would be to properly warm up the engine before attaching the lambda sensor and then removing it from the exhaust after doing any runs.
