About the Yamaha YFM400FW

Carburetor, rear drum-brake and starter repairs for FW-model ATVs.

Yamaha Motorcycle Logo

Yamaha’s history identifies the early YFM400FW as the Kodiak 400 4x4. Later 400-class ATV names and codes vary, so the full frame designation and fitted components remain the practical reference when ordering.

Choose float-valve and air-cut parts separately

The float needle and seat control fuel entering the carburetor and list 1993–1998 YFM400FW. Air-cut valves service another carburetor circuit, with separate 1993–1998 and 2000–2001 options; neither confirms 1999. Rear shoes list 1993–1999, while the starter motor shown here lists 1999 only.

YFM400FW model and application comparison
Model or repairWhat to check
1993–1998 carburetor partsFloat needle/seat and early air-cut valve are different components with the same listed year range.
2000–2001 air-cut valveA separate valve is featured; neither air-cut link confirms 1999.
1999 starterThe linked starter covers this single FW-model year.

Frame, engine and component markingsYamaha YFM400FW identification

Use the complete frame/model identification and the correct market documentation. Identify a replacement engine, carburetor or front end separately from the frame.

  • Keep the full FW suffix and any additional year/market code from the model label.
  • Compare the air-cut diaphragm and cover with the carburetor fitted to the ATV.
  • Check rear drum position, shoe dimensions and the starter’s mounting/drive arrangement.

A shared model prefix or similar appearance does not establish the model year or parts fitment.

Changing your YFM400FW riding position?

Compare universal handlebars and grips when replacing damaged controls or adjusting the riding position.

Check handlebar diameter, throttle type, grip length, cable reach and clearance. Universal parts may require modification and are not confirmed model-specific fitment.

Yamaha YFM400FW parts questions

Is the YFM400FW an early Kodiak 400 4x4 code?
Yes. Yamaha’s historical record uses YFM400FW for the early Kodiak 400 4x4. Still match the complete model code and year, because names and later applications vary by market.
Which air-cut valve is listed for a 1999 YFM400FW?
Neither featured air-cut valve confirms 1999: one lists 1993–1998 and the other 2000–2001. Identify the carburetor and ask for confirmation before ordering for that gap year.
What should I match when replacing the YFM400FW float valve?
For the linked 1993–1998 needle and seat, compare reference 1UY-14107-25, the needle tip and seat design with the fitted carburetor. The 2000–2001 air-cut valve is a separate component with its own application.
Which starter is listed for a 1999 YFM400FW?
The linked starter lists YFM400FW 1999 and reference 4KB-81800-00. Compare the drive, mounts and terminal with the installed motor, especially if the engine or starting system has been changed.
