How to Synchronise carburettors on the bench

It is important to have all of your carburettors synchronised so each cylinder is being fed the same air/fuel mixture. Synchronisation is normally done on the bike with the engine running but much of the mechanical synchronisation can be done on the bench.
This is a bank of four Keihin carburettors that have been built from scratch, being synchronised prior to fitting on a motorcycle.

Love the demonstration sir. A well explained method for balancing a bank of four carbs.

Thank you for this detailed video,I cleaned my 01' R6 carbs and can't get it started..this along with Pilot screw adjustment is my next attempt. I quit riding it 7 years ago.

Awesome video. One thing I never understood was how these are “fine tuned” while on the bike. How the hell are you supposed to access those screws?

They are very tough to reach and even harder to lock into position !
