Today I greased the two gears in the housing at the back of the speedo. While I had the cable off I sprayed some WD 40 down the cable. When I went for a ride it did the same thing. It appears to be ticking off the miles correctly just the MPH is crazy. Guess my next question is how do you know if its the cable or if its the speedometer bad? At the prices Triumph charges for parts it could become quite costly. Any input would be appreciated.
