Topic: CB400F Float Bowl O Ring

[Owned]

Does anyone have the size for the Float Bowl O Ring on the CB400F?

I've scoured the archives and cannot find it listed.  I like the molded ones from SCI, but they are expensive with shipping ~$32.

Anyone have the answer?

How about the o-ring size for the main jet?

[Kevin400F]

Main jet O-ring:  3.5mm ID x 1.2mm C.S.   (cross-section)
Float seat O-ring:  5mm ID x 1.5mm C.S.

For the bowl drain O-rings, I have been using AS568-009, which works out to .208" ID x .070"  CS

BTW, for the bowl to carb body joint, my actual preference is to use bulk 2mm O-ring cord, cut to the precise required length by laying it in the bowl groove, then joining the ends with cyanoacrylate cement (a.k.a common "super glue")
