I have had a continuing problem with my odometer stopping when it reaches any triple number turn over, removing it and cleaning/ lubricating etc did not stop the problem.
Although I did have another two, I decided to fit a black face speedo with klms per hr on the centre dial also. Trying to pick one up on line looked liked being expensive ($250) till I found a lady in UK selling one which I got for about $80 including postage.
Fitting was a challenge nothing seemed to line up but I finally got it in and both speedo and odometer are working well.
One trap I did run into is the petrol tank senders are not compatible it is different for the black fuel gauge. However gold gauge senders are $135 where the newer black fuel sender is only $40.
Anyone wanting a tank sender I now have a good one for sale.
