The end that goes into the speedometer. The end "somehow" got worn down and depending on the speed it acted different and the needle bounced. I put in a NEW cable and had the same problem. Then I thought the speedo head was worn.....wrong. I took it over to my "guage pal" and when we checked it with a set of dial indicators found that even the new cable end was smaller than the stock which he carried. I had him cut me a new one that is the right size on the end and now the speedo works very nice.
Its still a good idea to clean and lube though. | | |
