Leave the VBoost in-place. Unplug the butterfly motor when the key us turned on, & the butterflies open. Use the bike.

When you want to synch the carbs, plug the VBoost round connector back together, and the butterflies close. Synch carbs. Turn off ignition, back-on, and unplug again when butterflies re-open.

You removed the VBoost, & only have open tubes in-place of VBoost? You're gonna need a Uni-Syn tool. It works on 1 carb at a time.

I've got one made by Edelbrock. It's nowhere near Carbtune quality. In fact I'd want 4 of them to do a good sync. They sit on top of the carbs.

Pulled my carbs off today to bench sync and at least get things close. There are 3 screws that move 3 butterfly valves one has no screw and does not adjust. Is this the one I set the other 3 to?
