Install port adapters and cap them.
Warm up the bike to operating temps.
Park Bike and remove fuel tank and set next to bike.
Attach Auxilliary fuel supply to petcock.
Remove caps from port adapters.
Install manometer and hang unit over the bike.
Start bike and let idle, watch the fluid in the manometer, if one side creep up to the top and looks like it is going over the top immediately turn off bike.
To adjust *with bike off* look between the frame at the carb. Open the throttle wide open, you will see the adjustment screw rotate from facing forward, to right up to your line of side. Use a med-long flat blade screw driver to adust.
If the sync is way out turn adjuster about 1/2 turn.
Restart bike and verify you turned the adjuster in the correct direction.
Repeat until you are within a couple inches of fluid in each tube.
Rev the bike slowly to about 1/2 throttle.
Repeat adjustments steps until you are a couple inches apart in the fluid tube.
Check idle again - I usually go for a good average between the two speed settings. But I can usally get Idle with in 2-4 inches and mid throttle steady and not creeping too much as I increase revs.
Keep in mind the fluid is much lighter than mercury and is more accurate, so don't frustrate over perfection. Close is good enough.
Hope that helps - it takes longer to read this than acutally do it, once you have done it once or thrice.
