KEIHIN FCR‑MX37 Flat Slide Carburetor (Manufacturer Part No. 100‑G19‑A000)
Designed for off-road machines, this KEIHIN FCR‑MX37 carburetor is aimed at motocross riders seeking precise fueling and controlled throttle response. Built around a renowned FCR architecture, it incorporates controls and sensors designed for competitive use and spirited rides.
- Cold start and warm start controls — facilitates starting based on engine temperature.
- Throttle position sensor (TPS) — transmits position information for finer control and adapted electronic management.
- Accelerator pump — temporarily enriches the mixture upon opening to improve instantaneous throttle response.
- Interchangeable intake adapter — allows the carburetor to be adapted to different intake ducts, making it suitable for 4-stroke engines.
Known compatibilities: particularly suited for KTM 250 EXC models (2002–2004) listed below. Its installation requires precise tuning and adjustment of the carburation (jets, synchronization, TPS settings) to achieve optimal performance on your machine.
Manufacturer part number: 100‑G19‑A000. This part is intended for motocross enthusiasts and specialized workshops — a reliable solution for those looking to master the fueling of their 4-stroke without unverified technical promises.
