I know I've seen threads with pics about relocating the speedo on either this forum or the other one.
The sticking speedo needle has also been mentioned numerous times - get if fixed while still under warranty.
I don't have a true throttle stay, but I did install the Kuryakin Throttle Boss. I have the Kuryakin Iso Grips as well. If you go with the Throttle Boss I'd recommend the extended (slightly larger) one - it's not that big and really helps me a lot.
Good luck with your new ride; I love mine!
