79 KZ650 carb bowl tubing size

Hey guys, new to the community. I recently bought a 79 KZ650 that wasn't running. I'm rebuilding the carbs and I'm having trouble figuring out the right size tubing used to link the carbs. Does anyone know it off-hand?

Also, I'm swinched from the airbox to the air pods. I know they're not the favorable option, but I really like the look and want them on there. Would adding foam filtration into the pods (stuff the inside) reduce the air restriction enough for it to fire right?

Thanks!

A. The carb bowls on accelerator pump models use 1/8 " ID tubing for bowl interconnections.
B. The foam idea isn't a good one, rejet; up one size on pilot jet (type VM22/210 and to size #17.5)
Go to #110 main jets.

Great, thank you!

I added the tubing and reinstalled the carbs...and nothing happens when I try to start it. I've never really been down this rebuilding rabbit hole before, so naturally I've run into another issue.

At the risk of asking a loaded question, "what now?" I've pulled the carbs and sprayed starting fluid directly into the head and all four cylinders fired, first kick. I put the carbs back on and nothing happens when I try to start either way, kick or electric start. You can hear it turn, but there's no catch. At all, not even a cough. What would be the next step in troubleshooting?

I appreciate the help and patience while I learn to tackle this!

If you sprayed carb cleaner into the cylinder and it kicked over and you get nothing with the carbs on, seems like checking to see if there is gas in the carb bowls woud be the next logical step. If there is gas, then the gas isn't getting from the bowl to intake venturi/cylinders. This means that the pilot circuit is plugged and if you are using the choke, the choke circuit may also be plugged.
