Carb overflow tube size

[Athame57]

Before I go get it wrong on Ebay again, are the four carb overflow tubes on the CB400F 3.5 mm in diameter as per the inside?

That's the size I've used on my overflows. Push on fit and secured with wire clips although I didn't really need them.

Thanks Dave.

I recently bought some from Planet Silicone on eBay in nitrile rubber. Pretty sure the OD is slightly larger than the Honda original though (for 400F)

That's the supplier I used Ash on recommendation of NJ via another thread.
