    Rick walked me through this on the phone a few days ago, and I have misplaced my notes on it. My carbs are out right now, but I am about to mount them again. This is the best I remember of what he told me at that point...

    Put all the pilot screws fully in and the back them out 2 3/4 turns as a starting point...

    Start up the bike (if I can)...

    let it warm up and then begin to sync the carbs...


    That is where I get lost. any suggestions would be greatly appreciated.

    My YICS is shut off as of now (oil rags in the chamber)...

    Here's a short and succinct version I copied from one of Rick's earlier posts. It describes using just a single gauge, but I you have two or four then it could be even easier:

    -----
    Use ONE guage to do the whole rack.
    Measure the Vacuum of #-3 (Adjust 3 with the Idle Adjust Rod)
    Mark the MAXIMUM vacuum reading of 3 ... right on the guage ... with a sliver of masking tape.
    Block off 3 and read 4
    Adjust 4 to where your tape is marking the exact vacuum of 3.
    Block off 4
    Do 2.
    Mark 2 ... don't match it yet.
    Block off 2
    Do 1
    Match 1 to the mark you got doing 2
    Block 1
    Now match 2 ... to 3.
    1 is attached to 2 ... goes along for the ride when you Match 2 to 3!
    Your sync'd.
    ----

    Hope this helps ya.

    Is it possible w/o a gauge? Seems to me Rick described a way w/o it.
