Bad gas mileage and poor idle on older VMAX is caused by the rubber around the choke jet, holding the the jet open and the weak choke jet springs. Start the bike, select choke off, with your finger push the choke jets in on each carb, if any jet pushes in you have found the problem. A little lithium grease on the rubber boot will free up the jet (check that the nut holding the jet in place has not come loose). Caution the choke linkage should not push the jet in as it could damage the jet. Before you sync the carbs ensure to push all the carb jets in or you will have wasted your time. # 4 jet was stuck open 1/16'' and the bike that would go 200 km to reserve empty ran out of gas at 150 km.

That is only one of many potential causes of poor mileage. More often then that scenario is the float settings are not done properly which affects the entire tune and in turn usually poor mileage.
