450 Carb on a 426??

2 posts in this topic

Besides having to change up the jetting, will a YZ450 carb work on a 426? It's from an '03 450, and I have an '01 426. Need to know ASAP. Thanks!!

Should bolt right up.

I have changed all of my 01 426 body to 05 bodywork, and in the process I had to change the airbox as well, the new airbox boot lined right up perfect with the original 426 carb.

My guess is they are exactly the same design, the newer carb may be slightly larger bore? I dont know.

I think the 426 carb is a 39mm FCR, what is the 450 carb? maybe 40mm at most?
