For years I have had F6 motorcycles (Valkyrie Standard, Interstate, & Rune; Wing 96, 99, 02 & 08; and next week F6B) and one of the least mentioned positive features of the six cylinder engine is that it needs little or no balancing to run perfectly smooth. This reminds me of an encounter between a Valkyrie Club member and a former Valkyrie Club member who had just traded his Interstate in on a Road King. The former Valkyrie owner said "any more than two cylinders is just a waste". Without missing a heart beat the Valkyrie owner said "you are right, last night I pulled the spark plug wires to numbers 3, 4, 5, & 6 and drove up the street and back and it ran just like a Harley". The twenty or so bystanders died laughing.
