    I'm hearing a kind of whining and feeling a vibration in the clutch lever.

    Decided to take a video of the situation.



    Thoughts?

    One of them is a exhaust leak and the whine noise I'm not sure about but maybe in the stator move around the engine with a piece of hose in the ear or long screw driver and see if you can duplicate the noise at idle to try and pinpoint both noises.

    Can you duplicate the noise with the bike on the center stand, or does it only occur when riding?

    Also: Please keep all questions about your bike in one thread. It makes diagnosis much easier. The history of what's been looked at and done really helps.

    That sounds like the speedometer is making the noise, easy enough ...disconnect speedometer, ride bike see if noise stops . If that is it pull cluster open up lube the pinion and lube speedometer cable .

    It's the speedo. Unhooked the speedo cable and the noise went away.

    The first time this happened to me , I was slowing down for a stop light ...I thought I was dragging a tree branch it was so LOUD stopped looked over bike found nothing took off and it sounded like a jet engine , pulled over disconnected speedo cable ...no more noise. When I got home removed cluster , pulled speedo lubed the cable, the pinion inside speedometer, put it back together and no more noise. My theory is the pinion dries out after 30 plus years , all I know is it worked for me .

    I'm sorry, I'm not familiar with the pinion inside the speedo. Am I thinking about this correctly that I'll have to tear down the cluster ?

    Yes the pinion is connected to the speedometer needle , your option is to try to open cluster or look for a used speedo. I believe you have a 550 is that correct? My xj750 Seca has a different cluster that can be opened fairly easy , as to the 550 I cannot say how easy this might be.

    Been riding around without the speedo hooked up... The tach started whining. I guess I need to take them both apart ;-)

    It's most likely just that the cables need to be cleaned and lubricated.

    So, I pulled the speedo cable, wiped it down, sprayed cable cleaner in the shaft to lube it. nice junky liquid came out. Still got the noise. It's more intermittent now. So that's better. I'm still thinking that i need to lube the speedo itself. Can I just spray chain lube into the speedo?

    The innards of the speedometer are sealed. The only thing that can be lubed from the outside is the socket for the cable end.

    Cable cleaner is not a suitable lubricant for a speedometer cable. It really needs to run in grease, or a sticky chain-lube.
