I know the feeling. My first Goldwing was a GL1500 that I purchased after some friends inspected it in Tasmania.
It was then moved to another friends place who happened to live just around the corner where it remained for a week or so until I had the chance to fly over and ride it home. Leaving my friends place on the GL1500 I thought what have I done. Having never ridden a Goldwing before this one felt terrible. After about 20 kms I pulled into a service station and added about 20 psi to the tyres and that was the beginning of my love affairs with Goldwings.

I've actually ridden beyond the bollard/fence to the other side and back.  Anyway, where is this?

I had been trying to check tyre pressures on the new wing over the past few days and wasnt sure whether the gauges I tried were faulty or not fitting or something else. So I took Goldie back to the bike shop wher I got a rwc and asked about it. Turns out the gauges were correct and there was 16.5 psi in the front and 20 in the back. I wondered why it took a good push backwards to exit the garage now I know. Apparently she hadnt been ridden for 12 months. It started first go but No One thought to check the tyre pressures. The tyres felt firm enough but obviously they were really low.
 Its amazing how a heavy bike can still ride well enoughwith low tyre pressure. Ithas a tpms system with the phone but I havent managed to get it going yet. Big oops.
PS it goes around corners much betterer than before.
