    cx 500 tach noise

    Hello all, I have owned a 1980 cx500 since new and was riding last month and had a whirring noise coming from the tach gauge. I disconnected it and all was fine . I assume it needs lubrication or has a worn out gear. Are these easy to remove and fix . Does the electric wiring just unplug from the unit. Anyone else had a problem like this ? Thanks JG

    If it just needs oil, you can do it without removing it from the bike. Just disconnect the cable at the tach, then give a small shot of oil to the end of the mechanism in the tach. It's pointed down, so you'll need an oiler like the Zoom-Spout Oiler (look it up) that allows you to apply oil via a skinny tube spout in an upward direction. I did this for my bike three years ago and it hasn't squawked since.

    Prior bikes I wish I still owned:
    1965 Ducati 250 Monza
    1973 Kawasaki H1E 500cc triple
    1968 Honda CL450K1 scrambler
    1984 Kawasaki KZ700A

    It's not too often you find members who have a "since new" bike still puttering around. How many miles on it? Also, depending on mileage, it is not often that it's been 36 years before needing any cable, let alone the tach. Tach and clutch cables are usually the first to get used up.
    Best to just replace the cable.
    Use light mineral oil in the tach head as above, or you can try teflon or moly dry lube sprays.
    May the myriad of wheels in your head, keep the two wheels between your legs rubber side down.
