New Smoker! 2022 Yamaha YZ125

Improved Fueling
New high-precision Hitachi Astemo® Keihin PWK38S carburetor features a power jet, throttle position sensor and 3D-map-controlled CDI unit for precise ignition timing. The result is clean, crisp throttle response, superior rideability and excellent over-rev character.

TPS for ignition timing is smart. It will be interesting to see it’s power curves.
