Hi I am not sure if the question is well formulated in English but the issue is as follows: Have a speedo R80G/S W=773 Needle is crazy, odo went to zero, nothing seems to work. Can't find direct swap. But was offered a W=747 What do I need to change and were to make this speedo work accurately Question # If I buy a W=773 speedo from another bike can I use the guts of that one to repair mine and if so what chance I hae of success? The issue with the other speedos is the location of the trip meter, unsuitable for the R80G/S pod. Yes Yes I know I should buy a vapor but I got a Sigma as a spare and well I am stubborn and old bikes are to be kept original and functional so I want to fix this. Besides I do not like to have to concentrate on small screens prefer a needle for easy reading. Thanks for clarifying this and or suggesting another alternative, but I want to fix this speedo!
