The following shots are of my ST when I performed the TB Sync last spring. I simply removed the tank, laid down some padding and propped the tank at a 90 degree (plus) angle to the centerline of the bike, resting the front of the tank on a tank bag. The hoses were long enough to plug in without undue stress on the fittings. With this configuration I was able to adjust the screws while it was running. Kind of a shade tree mechanic solution but it worked.
Trusty Triumph tank bag saves the day!
