buzzing noise
« on: June 04, 2009, 12:26:09 PM »
I was riding the other day and could hear an audible pitch buzzing when the engine revved. At first I thought it was my keychain because it rattles like that quite often, but I grabbed it and the noise continued. It is coming from in front of me, so it has to be something up there somewhere. I have not checked my valve clearances yet, but that is my best guess. Either that or sloppy control levers.

Has this happened to anybody, have you figured it out? Thanks a bunch.

Is it speed sensitive? Could be the speedo cable.

didn't think of that. Or the tach cable for that matter. I haven't lubed them since I bought it, so I will check.

Tach is electric.  Grease the speedo cable input carrier where the speedo cable plugs into the speedo head.  Do very soon and you'll never have to replace your speedo head.  Don't do it very soon and you'll soon wish you had.  The sound will only get much worse.  You won't believe the noise and vibration it can make, if left alone.  This isn't a V only gremlin.  It's an old Japonese speedometer gremlin.

Its most likely the input bearing on the speedo (where the cable attaches) I tried forcing grease up the opening that the cable screws on to , but wasn't satisfied with the result. I drilled a 1/16 hole just above the threads that the speedo cable attaches to squirted some lubriplate in there and then installed a self taping screw to seal it up. Worked like a charm and I can lube it every year.
If you ignore it it WILL break the speedo cable core.
Ask me how I :D know!
