Use a soft cloth to clean the mirrors, and make sure to spray on some mirror cleaner. You will be able to pick up a mirror cleaner at your local supermarket. After it has been sprayed and wiped, use a dry cloth to wipe away any excess water.
If both speedometer and odometer do not work, usually the pulse signal are missing. E.g. the wiring coming from the rear differential where the sensor is located, can be deteriorated (broken or shorted). If speedometer only is inoperative, it is easiest to change the whole speedometer. To repair it, you need to be able to work on electronics, disassemble the speedometer unit, access the printed circuit board, and usually replace the leaking electrolytic capacitors on that board, as well as clean the circuit board of the electrolyte. Some other components may be broken also.
You can not successfully clean an oxygen sensor. You need to replace it.

Harley uses a belt instead of a chain because chains are messy, need constant adjustment, wear out sprockets and have a relatively short service life. A belt on the other hand is clean, rarely needs adjustment, is easy on sprockets and has a very long service life. 100,000 miles or more from a belt is very common. Harley chose not to use shaft drive because it is inefficient in that it robs power from the bike due to friction.
