Waspish noise ... (but it didn't start with a tick ...)

[RandyRex]

Has anyone encountered the "angry wasps" noise when your girl is up around 5K? My suspicion is the Timing Chain is slack and flexing out into a casing, or something ... but, I'm still learning the ways of the GS ...

Check the heat shields on the exhaust pipes where they pass under the motor; they're famous for coming loose and vibrating at about that rpm. And the crossover clamp underneath as well. The whole exhaust system is a potential percussion section.

Famous, you say? Oops, I guess I got had by a goofy noob trap! Thanks, I'll check the entire percussion system .. (D-ohh?)

It probably some part of your bike sympathetically vibrating with the motor

My horns vibrate at a certain rpm

I've got something on my bike harmonizing at a perfect 5th above the engine at 5000 RPM. I've decided it's nothing to worry about, until it is.

Have you eliminated the tacho drive cable?

It's possible. Thnx for the response

This might become my philosophy, too. TY.

No sir, I have not, but funny thing happened about a week past ... tach cable came off, out of the blue, and when I reconnected it, the entire cable was saturated with motor oil .... I thought it odd, ruminated about the effects of gravity upon hot liquids and old seals and banished it from my mind, until re-occurance ... now, I think I shall disconnect it, wrap the end with ducting tape temporarily and see if the noise has disappeared. Thank you.

Any chance you might be willing to give us a clue what bike we are discussing?

My apologies, a 1979 GS850!

I had a similar noise on my '83 850 GL
It was the heat shield - the mount had rusted and it was loose
Got a clamp on it and it was quiet again

[Gorminrider]

Gas tank caps can buzz.
