I cleaned all the connections and cleaned the sensor itself. Still nothing, Thanks for the replys

The Rev counter works , I have no clue what has been done as I bought the bike on Saturday. All The wires look normal.

LoL Also when I unplug the sensor from the wheel , it doesnt change anything.

So I bought myself a 2005 Yamaha TZR50 And as usual it has the speedometer problem , but my problem is a bit different. When i start the bike the speedometer reads 0MPH and after the bike warms up the speedometer says random numbers upto 50MPH eg.8,32,50,42,1,21 When I rev the bike in neutral it increases the speed eg.10,20,30. Any ideas? THANKS.
