Using a Crf450 floatbowl on a Yz450f

I read a review on Bobby Bonds 09 Yz450f in Dirtbike Mag A few months ago and it briefly talked about him using a honda crf450 floatbowl on his Yz450f. Curious if anyone out there had some more insight on the reason or benefits of this?

anybody?

I use one on my 444... only cause its got a LJ. Newer 450 should have them tho....?

Sudco lists only one float bowl for the horizontal, or side draft model FCR, and I'm not aware of any differences between the bowl on a late CRF450 and that of an '05 or later YZ450F. The YZ450 has had a leak jet since '05, so I don't see anything to be gained by it at all.
