Intake rubbers

[Descam Moto]

Hi Guys,
A quick question for you if you don't mind.
Could anyone on here tell me the mounting spigot diameters of the carbs and inlet stubs for your bikes please.
I'm trying to get an angled rubber to suit a classic race bike project and the CB750 ones look like they will do the job.
I'd just like the internal dimensions of these rubbers to see if they might do the job.
Thanks.
Ade

There are several different sizes depending on years.

Thanks for the reply, but could you give me some dimensions please?
I was looking at 79-83 cb750 rubbers, but don’t know the dimensions.
Could do with something around 35mm inner diameter.
