    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.

Funny noise? Maybe?

Recently acquired
1985 GS550EF (minus the F).

Bike seems to run fine, still needs the carbs adjusted, but otherwise has been mechanically sound.

Stock airbox.
Has an oil cooler (not sure if that was stock, but I'm assuming not).

Now the noise occurs between 4500rpm and 7000rpm, in every gear. Below and above that the bike sounds 'normal'.

But between those RPM I get a very high pitched buzzing sound coming from somewhere near or in the engine. Anybody have any thoughts?

Also --- is there anything special I need to know about changing the oil on a bike with an oil cooler?

Thanks,

Satch
 
resonance vibration noise, dont worry.
they came with a oil cooler standard as this is the bridge years between the air cooled GS and the oil/air cooled GSXR 83-85/86ish are the only GS that came standard with a oil cooler.

you changed the oil just like you would for one without the cooler.
 
A carb clean and sync may do wonders for quieting down that vibration as well Alex.
 
you have to stop thinking of responses to the R thread while riding your bike.
Tighten stuff and see id that helps but ill always go along with the carb sync
