Gauge problems

On a 2005 model you should be able to replace the sender with the newer Wema brand sender. They are much more accurate and dependable. The speedo seems to be plugged with debris. You can drill the trash out of the pitot tube carefully and then back blow the trash out if you need to.

Its not bad on a 2005 model, check alignment of the sender under the access plate in the main seat box area. Otherwise you just remove the seat box itself.
