Has anyone heard of a CRF 450 carb being the same as a
YZ/WR carb. Has anyone made a successful switch ??? I've got trouble brewing and I might need a carb and a CRF carb is 2/3 the price !!!

I think you can do it, but the cr-f bellmouth inlet is a little different. It still should bolt up though.
Try getting a standard fc-r from sudco, tell them to jet it for a suzuki goose.
Then you will be getting the good sh#$.

The CRF is 40mm and something is different about the bore if I remember correctly. Like it's oval shape or something. If you can borrow someone's CRF carb then try it out and let us know how it works.
