Tony, have you experienced loosing them?
Would a proper fitting piece of hose connecting two carb vacuum ports together be ok to do? Or would that cause problems with the individual carb vacuum balance. Mark
I seem to recall someone (SNARF?) having petcock and/or cruise control problems by using a tee between 2 carbs to provide the vac source.
The carbs are not tied together during a carb sync, each is connected to it's own independant meter, not tied together. Others have had problems with LOW vacuum by tying ports together, as you said, due to which piston is moving up/down at the time. Tying ports together also actually creates a small vac leak in each carb, or so I've read from trusted sources.

Yes he did and it drove him absolutely nutz trying to figure out what was wrong with his bike... In the end he found out that he was starving for fuel when running hard as his petcock was closing up due to vac loss between cylinders.Yep that was me. I had never paid any attention to the bike when I got it. When we rode home from the rally in Tomah, my wife was riding my 02 so we never really rode hard. After I got it home I still sorta took it easy. Then one day I decided to flog the cr@p out of it and thats when the hair pulling started.
The only thing I would add is that it depends on the type of gauge one uses when doing the carb synch. Several methods do in fact tie two carbs together.
One such method ties both carbs together to two bottles each containing a bit of fluid and those bottles are in turn tied together. One can tell which carb is pulling more volume by measure which direction the fluid flow, from bottle A to B or vice versa. For a different method, I made one out of a sort of diaphragm ( condom) held between two chambers. I can tell how to adjust the carbs by monitoring which way the "diaphragm" is being pulled.Oh man, I remember that thread. That was ingenious and funny all at the same time

I do not know what model that would be but I can tell you that will not work. Carbs have to be synch separately in relation to each other . If you join them together then what you did is not called 'synchronizing carbs'.
