carb syncing

LOVE that pipe, by the way. It took about 45 min to run a tap for the can mount! PITA. more time doing that than replacing the gaskets!

You will need to pull the caps/tops off of all 4 carbs. Once you have the sync set up and hooked up, you start with carb #3. Looking down on the carb there is a small standard screw and a locking nut. You loosen the nut and adjust the sync by turning the screw.

Then sync carb #2 off of #3 by evening out the fluid height levels till they are equal.

Then sync to carb#1 and then carb #4. Most have carb #1 and #4 slightly higher (but equal) then carbs 2 and 3 (which should be equal in height).

The challenge is keeping the heights right while tightening the lock nuts. There is a tool that helps with this but you can do it just fine..you need to hold the screw driver in and use a small wrench to tighten the nut.

Good intentions, but they do not apply in this case.
The only part that applies is the part about taking off all four carb tops.

The VM carbs on his bike have NO master carb, so it does not really matter which one he starts with.
The carb slides are all directly attached to a single rod that runs through the tops of the carbs, so none of them slaves off another.

That is what makes them easier to sync than the BS carbs.

Personally, when I do a carb sync (either type of carb), I will leave the gauges hooked up while I do the mixture adjustment.
After doing the mixture adjustment, I will verify that nothing changed with the sync.
Have never seen any change, but it gives me warm fuzzies.
