ulflyer,
Congrats on your new SWing. Sounds like you are doing the right maintenance to it and hope all goes well. I run 32psi in front and about 38 psi's in back. It is a couple above what Honda says but I think that is one reason I get about 10,000 miles on my tires and I could go further but I hate flat tires so I change them out quicker.
I have the Metzlers, but also did the same air psi's in both Diablo's and the OEM Hoops. I know others here are "by the book only" but just do what you think is comfortable.
I would check the air filter too when you get a chance. It seems when I forgot to check mine I notice the mpg's go down. Let us know what you think after a few days of riding. I know I still love mine after having many mc's and the Reflex and Majesty.
