What spark plugs are used in a 1984 Yamaha Virago 750?

According to the Clymer service manual, the spark gap should be 0.7-0.8 mm, as with most of these bikes. Actually, the required plugs (NGK BP7ES or BPR7ES, depending on who do you trust - the difference is an incorporated series resistor in the "R" plug) seem to come factory-set to that gap, but it never hurts to check, I guess...
