1978 Honda CB550 Supersport - My first retro bike rolling restoration!

Ahh my mistake and ignorance showing through, I was referring to the air vent pipes that connect in-between the carbs. I'm assuming that should be 3.5mm pipe then? Typically I have 3.2mm pipe already and will soon have 4mm pipe as well.
As long as it's not going to have any operational impact then that will have to do for now. I would imagine that ordering a replacement set from the US at a later date to replace all of them so that they are matching would be the solution. It could be that I rejet later with an exhaust change anyway.

I've just bought some hose to replace my old split and age-hardened original engine breather. Finding that the OEM item is discontinued, I got some of this:

Fits perfectly, and is a bit more flexible than the original.

By all means use that jet "for now" but I would be purchasing one to have in the spares box ready for the next time the carbs come apart

I'd like to support the contra view, in that the jet is really just cosmetically damaged and dressed off with a file will perform as original. The seal and bore being the critical performance elements.
As it's part of the original set ( more of us are holding the view that original brass in good condition is hard to match with replacements) and these running best with accurate fuel metering, I feel it's advantageous to keep an original.

Yes, I seem to be a voice in the wilderness on this particular option. However it doesn't hurt to hear a different viewpoint
