The actual value is not that important, what is important is that all cylinders read the same value. It sounds like you are doing this with a single gauge? I find that adjusting one carb always has a small effect on the others. I bought a 4 gauge set and balanced all 4 carbs in one go, if your value has changed significantly the only thing I can suggest is to go back and repeat what you did before but now trying to get 10 1/2 reading on the carbs. Are you aware that there is a specific order that the carbs MUST be adjusted in otherwise you will have readings all over the place? I would also strongly suggest getting at least 2 gauges so you can sync the two left cylinders, then the 2 right and finally the left to right bank.. Hopefully someone can post the exact sequence that you must adjust the carbs in as I do not have a manual with me.

As Gary stated, the actual reading is mute. Take your reading off of #3 (Baseline) then adjust #1 to match. Right side is balanced, then take a reading off of #4 then adjust #2 to match it. Left side balanced, then adjust #4 to match #3, this wll balance the left side to the right. It can be done with one gauge. IF you use multiple gauges the you must measure one of the ports with all of them to get the error correction.

should the carbs be synced at both the lower rpm and at around 2900. If I get them in sync at the low they are out at the high...and if I tweak it at the 2900 rpm then it's off when its idling.

The best reason to sync the carbs is to minimize off idle acceleration(950-1500 rpm).this is where the Percentage differences are most noticeable.A 1% difference at 5% throttle a large amount,a 1% difference at 30% throttle isn't that bad.Syncing at the 1000 rpm level will greatly smooth out the take off,and quiet that annoying rattle.

You really need a 4 gauge set up. #4 (left rear cyl as you set on the MC) is the base. Non-adjustable. I have found when you change any setting it affects them all especialy the side you are working on. The goal is to get them all to match with #4 where ever that maybe. I myself prefer the mercury carb stick. Others will differ and their way is not wrong. Adjust at idle speed setting.
Hope this helps.
Enjoy the ride. They are all good, just some better than others.

I got the mercury set from sabre cycle.

I did get them to line up with playing with it again tonight.

My 2nd cylinder would occasionally do a little pop sound and drop but come right back up. I think I'm still fighting some bad gas issues with it sitting befor I bought it.

If it helps, here is a very good carb sync video.
