Question about 1985 Yamaha FJ 1100
Just the other day my tachometer stopped workin correctly. It just climbs real slow and won't go past 4,000 rpms. I think I heard somewhere that sparkplugs will do this but I'm not sure because the bike is still running fine. Also I checked the cable and it looks fine. Thanks
Bad plugs or other electrical problems can mess with an electronic tach. Yours has a cable so it sounds like a mechanical drive. If so, it is probably your drive cable. take it off and pull out the inner drive spring, clean it well, as well as the inside of the outter cable, then either use a light grease or oil to lube it before re-installing it. Check both ends of the drive cable for wear or rounding off.

Looking for wiring diagrams for digital tachometer with trim indicators and warning signals. Mine had the plastic trip arm break. No trim reading on Tach face. Replaced trip arm forsensor arm and now have no reading on the tach at all except extremely light tach Number. All other electrical components work OK.
