Erratic rev Counter

I Went out on the bike ( B6 ) today first time since October

while going along the road up though the gears the rev counter is jumping about mega- from 7000 rev to red line.
If i stop the bike and just rev bike to 5000 revs and hold it at that the needle moves from 5000 to 7000 spontaneously but no change to rev of bike it self.   
Noticed once i was on motorway sitting at 5500 to 6000 revs in top gear it just sat there


any ideas maybe no explaining it very well but basically it no right whats happening could it be a dodgy connection with it lying outside under a cover all winter or a coil problem ?

I took the tank off today and cleaned the contacts on my coils .I  will take clocks out tomorrow and see if there is any corrosion there . not sure where it get the reading from thought it might be coils or could it be alternator ?

Any suggestion would be appreciated

clocks

most probable that there is a bit of moisture somewhere in the clocks or loom to them. As you will be taking them off give them a good clean and maybe leave indoors for a day or two to remove moisture. If the bike was indicating a fault code they usually go to a specific rev point and return.
