    A Special Note about Email accounts!
    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

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

;) 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? :p Oops, I guess I got had by a goofy noob trap! Thanks, I'll check the entire percussion system .. (D-ohh?) :eek:
 
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.:single_eye:
 
Have you eliminated the tacho drive cable?
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?

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 ;)
