BFO Replacement Carburetor For Yamaha YZ400F YZ426F YZ450F & More (1998-2009)

Hey dirt bike riders!

If your Yamaha is acting up and needs some fuel system love, check out this BFO replacement carburetor.

It's designed to fit a ton of models, including the YZ400F (1998-1999), YZ426F (2001-2002), YZ450F (2003-2009), plus the WR400F, WR426F, and WR450F.

It also fits some Honda, Kawasaki, Suzuki, and Husqvarna models.

It's a direct replacement part, meaning it should bolt right on.

This is an aftermarket carb, not OEM, but it's made from aluminum and has a single barrel with a mechanical choke.

Just a heads up, it doesn't come with instructions.

It's got all the right measurements, like a 55.4mm air filter side inner diameter and a 40mm intake manifold inner diameter.
