Motorcycle Repair: Carburation on a Kawasaki, kawasaki kz1000, vacuum type

Question
I don't know what to do with the vacuum tube connectors on two of the four carbs on a Kawasaki KZ1000 1979. Do I simply block them or do I connect them to something.Please advise.

Answer
Hi John,

I cannot see what you're working with. Can you send digital images?

What type of petcock is present? Gravity or vacuum type?

If in doubt, plug em all.

FYI... I return tech files by email. There was no email address with your question as requested and explained in my instructions.

Respectfully,
