  I balanced the carbs using the info in the tech section. They said to use a four gauge system. I want to make a six gauge system so I do not have to switch gauges . Is there a reason to only use the four gauge system.

All I can think of is that 4 is less expensive than 6. Having 6 gauges would certainly make it quicker and easier. I user a 4 gauge set myself.

Absolutely no reason a 6 gauge system won't work.  I have a 1 gauge system on a manifold.  I clamp off the cylinders don't want to read and read the one I want to.  Make all connections before the bike gets terribly hot.  cooldude

Six is the easiest way to synchronize the carburetors

I like one good gauge and six aquarium valves. Also below gauge I have a valve to eliminate needle bounce.

+1 on only using one gauge. 6 gauges will all read different as each one is not built exactly the same. I know this from a previous life where I had to calibrate gauges used high pressure equipment. You are only comparing each carb to # 3 regardless of what the vacuum is. I too use a set up like signart is showing here. Works great. While you are at the fish tank store get the silicone air tubing. This stuff is really pliable.

You are correct there Brian. I realized there would be such a problem when I purchased

the gauges, so I bought ten gauges. They were very inexpensive, less than 5 bucks each

and it took all ten to get six that matched. I hooked the all up to a common manifold to

get six that were the same. I had priced those little aquarium valves and found them

very pricey!

And finally, the convenience of having the ability to see all six continuously makes

comparing very easy.

I agree here, although you'll probably get flamed from the "multi-gauge" advocates here!

I too deal with "certified" gauges that have to be calibrated on a certain frequency.
So unless you're using calibrated gauges the carb balancing quite possibly will be off.

I use the "one gauge, "Y" connection, and a couple of hemostat clamps" method.

I use one guage and don't need  to calibrate a multiple gauge system.

I went ahead and invested in a very good gauge for my set up as I can disconnect it and use it in my truck hobby which I do often. Before I use it on my Valkyrie again, I will invest in some better hoses as these get very soft from the heat and could potentially collapse or come off during the procedure.
Now that I am more familiar with the procedure, I would be a lot quicker, but I suggest removing the alternator cover as a precaution. Also a fan in front of the radiator.

here is a link on Ebay for a 5 way manifold. I use 2 gauges. The first one is the reference and the secon is used through the manifold to read all 5 other intakes one after the othe without having to disconnect anything

No calibration of gauges necessary.

Here is my set-up. Using an old vacuum/pressure gauge that I had from working on older cars and trucks.
