Mikuni TMX38 caburetor with powerjet.
This early TMX series carburetor features a flat slide design in a smooth bore venturi with powerjet, to provide improved throttle response and wider powerband. It is lightweight and has a compact body. The powerjet adds extra fuel from half-open throttle and up (can be disabled). The TMX38 works best on 250cc and up 2-strokes, and is a great performance upgrade to many OEM carbs.
