It does not matter what the pressures were for the stock tires. You only need to know what the pressures are for the tires you bought. Customer service is very important to me. I would have asked to speak to a manager, the second that kid finished saying, talk to Honda! UNACCEPTABLE! After getting the correct pressures from the manager, I would have informed him what the kid said, then informed him that this would be my first and last set of Michelins that I would purchase. Thats just me...
K.I.S.S Keep It Simple Sir!

Dumb people, like that kid, is what makes things complex. Every set of tires have their own specific tire pressures. You bought Pilots Powers for your CB-1, and the set you bought has specific tire pressures. Period. Once you set those pressures, you are good to go. The ONLY time you would need to adjust those pressures, is if you experience extreme weather/temp changes.
Welcome and enjoy your new "shoes"!
