A buddy of mine has a 400EX and recently removed the choke from his carburetor because he had read on EXRiders that it would give it a bit more snap and power. He claims he can feel a difference, although its a bit harder to start now.

Anyone ever done this on the YFZ?

The Honda has a true "choke", a butterfly valve that restricts air, causing a richer mixture when closed.

The YFZ has an "enrichener". This does not use a butterfly valve, but rather an extra passage that allows a rich mixture to be introduced when opened.

Still, most people refer to it as a "choke". :)

Hope that helps.

Very good explanation of how the "choke" on the FCR carb works.


And no it will not help with flow at all by removing.
