You'll see 9 this weekend, Instance!
Mag(etc)... would you mind posting the pronunciation of your name one of these days?
As for the two-up, make sure you tell your passenger that not only is it OKAY to move his/her head, it's actually a really good idea to have them ALWAYS move their head to the side your turning. This has two benefits. First, the person will unknowingly help you in balancing. Second, they will have a clearer view of where they're going.
I always tell a passenger the rules before letting them ride. First and foremost: wave to other motorcyclists! Second, put your arms around me and you will automatically be in the right position. Third, move your helmet to the side we're turning.
The one thing that took me a while to get used to was when the passenger puts their hands on the tank when I'm braking. It's a benefit in that it keeps the weight off you if you're braking hard, but that would be a violation of the only rule YOU have to follow...
Make the ride as enjoyable as possible for your passenger. Do not scare them into not wanting to ride w/ you again.
