Yamaha Virago Carb Sync (1984 XV1000)

Carbs are back in the bike after a full ultrasonic cleaning, installing a K&L carb kit and setting the idle mixture/fuel jet screw for my altitude. Properly ran all the fuel lines (replaced 2), cleaned and lubricated the throttle and choke cables and reinstalled the vacuum hoses. Made my own carb sync tool from 2 vacuum gauges and ball valves and followed the service manual on carb synchronization for my specific year - 1984 XV1000. Turns out the procedure for my bike is slightly different from some of the other Viragos and that procedure is detailed in the service manual. Adjustment is made by the adjustment screw located between the two carbs - easier to get at when the tank is lifted and the seat is removed. Remember that the cylinders do not fire at the same time or even 180 degrees from each other so the needles in the gauges will not peak at the same intervals - you'll have to just average them out and get as close as you can to having them balanced. This procedure should be done when warm and only takes a few minutes to complete.
