Been having a problem with the tach on my 855. Needle keeps bouncing around and not registering correctly. Had troubles locating the end of the cable opposite the tach, but with help from this board was able to find it. Lubrication of the cable did not correct the problem and I decided not to try to fix it because of the difficulty in removing the tach. Now my better judgment tells me to try and fix it before matters get worse. Can anyone advise how to get to the tach so I can remove it and install a new one? Looks to me that the fuel tank may have to be removed to get to it. Don't really see any way to get to it. Thanks in advance for any insight or suggestions.
