Definitely each and every mile/km, yrd/meter, inch/cm needs to be on a SOHC4 Honda CBxxx built between 1969 and 1982. For the Michigan route, I'll be on either my '77 CB550K3 or my '74 CB750K4 from Detroit, through Hell and on to Kalamazoo. From there, SeanBarney41 on his CB will take it up to meet RatRacer on his CB as we all head to the land of the Cheese Heads.
With that in mind, when "IT" heads north out of Kalamazoo, I'm planning to ride my Honda made, 4-cylinder, 2-wheeled, vintage, single stick opposite the crank of each cylinder "support vehicle". Otherwise known as an '82 Goldwing 1100 Interstate. But hey! the Mrs wants to come along and I alone am the "load capacity" of my 550!! But as stated above, each inch/cm of the Michigan route has a SOHC4 Currier.
