Synching the carbs on an 1100 can be a daunting task....

I had the left side matching and the right side matching but not left - right.
What I did was turn up the idle a little bit and start to work all of the synch screws...
It took a little bit of time because as I changed one it affected all the others - I have a 4 gauge manometer so I could compare live real time.
I didn't worry about the actual numbers on the vacuum -- only that they all 4 matched and were balanced...
then I adjusted the idle down and re-did the synch (which was pretty close)
The problem before was whenever I did the first synch at lower idle the bike would cut off...
Once I turned up the idle I could make adjustments to get it closer to correct without the bike turning off.
I think I had the idle at about 1500 to 2000 RPMs -- then down to just under 1000 later..

Once synched the fuel economy went up, the bike started easier, and had more power at all speeds (subjective analysis)
