Yes Chris, I made a mandrel that incorporated an old hub, that was first balanced, and then wheels are mounted to the mandrel. the balancing frame is set level and uses overlapping bearings on each side as a toolroom grinding wheel balancer has. It works for me. Prior to making this fixture I found some motorcycle shops were able to balance A7 wheels for me. I know some readers of this forum will not see the point. However my view is that with the limited performance an A7 has every small loss we can eliminate adds up to a worthwhile gain. Added to which if you travel at speeds above 50mph an out of balance wheel, particularly at the front, can at times cause alarming handling issues. Even below 50mph they will sap power, as will any out of balance rotating/reciprocating component. To make a real difference though we need to go beyond simply balancing wheels but look at dragging brakes, bearings, incorrect set up of carburation, ignition etc etc.... its a long list. But get it all right and it is worth the trouble as I and other like minded enthusiasts have proven time and time again.
