Carb vacuum ports too small?

I'm trying to sync the carbs on my '99 katana, but the tubes on my manometer are too big to fit on the vacuum ports. Are there adapters for this or something? I've done the carbs on my 80s bikes and they're all typical 3/16"-ish

try some small vinyl tubing pieces. They might make up the difference. I've done that before.

If I remember correctly, Suzuki requires a specific adapter unlike other manufacturers. Just like their oil filters

There are adapters/different size brass fittings for your vacuum ports.

Figured it out. The ports were *just* big enough.
