42MM Carb Carburetor With Jets set, Japanese Authentic – Made in Japan. The Kei-hin CNC machined smooth bored PWK42. (often an OEM or popular performance upgrade carburetor) is commonly used on or adapted to. Several classic and modern 2-stroke dirt bikes. Great for large big bore 2 strokes. Frequently used as a performance or replacement carburetor for big-bore 500cc 2-strokes. Yamaha YZ250 – Fitted stock as the Keihin PWK 38S on YZ250 two-stroke models from 1999 through present model years, and adapted to earlier years. Used on YZ125 models from 2022 to the current model year (though 38mm is large for a 125, some riders tune or modify them). KTM 250 / 250SX / 250EXC. Used across various 250cc KTM two-stroke enduro and motocross model years in the late 1990s and 2000s. KTM 300 / 360 / 380. Common on mid-to-late 1990s and early 2000s KTM large-displacement 2-stroke enduros and MX bikes. Kawasaki KX250 kx500 – Widely used as a stock or aftermarket performance carburetor swap. Frequently used by riders swapping out stock carbs for crisp throttle response and better mid-range power.
