Complete Ready to install Carb For your Yamaha 2001 YZ426F:

This is the newest version of the Keihin FCR Yamaha 2001 YZ426F Carb, which offers many fine-tuning options, updates, and performance upgrades, allowing this carb to perform best in any situation.

This is a rebuilt option (pink hose pics). Click our new option above for a new-in-box, then add all upgrade options to complete the conversion.

The difference between this Yamaha 2001 YZ426F carb upgrade vs. others:

  • Advanced TPS sensor (ready to plug into the wiring harness.)
  • New adaptor boots.
  • Tuned for each order (please include elevation, bike mods, mileage, and riding style on the order notes page).
  • Upgraded Baffled float bowl (allowing fuel to flow at any angle the bike is leaning: whips, wheelies, off-roading, etc.)
  • Correct needle (allows for a smooth power band and the ability to pull endos without stalling the engine.)
  • Black Neoprene Genuine Keihin hoses (these remain functional three times longer than the Keihin OEM Pink hoses.)
  • Note: These carbs are set to order! Tuned carburetors do not require constant jetting unless there is a +/-3000ft change in elevation. Still, even then, a simple adjustment of the fuel-air screw and idle can maintain a properly running engine.
  • “No need to sacrifice power for the worry of jets.”
  • The product photo is for reference only; the part you receive will be specific to your bike’s make and model provided.

This carb was designed in Japan specifically for a 4-stroke motorcycle!

Two-stroke carbs (such as Lectron and Smart Carb) work well on all engines! The problem is that 4-strokes take twice as long to produce a “power stroke”, where both the TPS and Accelerator Pump Preload the Spark timing and fuel before the engine produces the vacuum needed to get a two-stroke style carb operational.

This video shows a stock DRZ400 with only an exhaust and this carb upgrade. These two products, when combined, will produce over 25% more horsepower and a 29% increase in the torque curve.

We also have a “Two-stroke style option” for a more economical modification.

Below is what will be included with this Yamaha 2001 YZ426F Carburetor when all upgrade option buttons are selected above:

  • Main & Mid Body
  • Float Bowl
  • Throttle Slide
  • Roller Plate
  • Throttle Position Sensor
  • Throttle Connector & Spring
  • Fuel Inlet Valve
  • Accelerator Pump Upgrades
  • Tuning and Jets set for each order
  • Needle & Seat Valve
  • Hot-Start & Choke Knob
  • Fuel/Airscrew Billet Adjuster Upgrade
  • Easy Idle Adjust Knob
  • Complete OEM installation of Keihin Gaskets
