    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.

I replaced my exhaust gaskets and th eold ones looked good.There is no sputter like a exhaust leak but I still have this weird noise between 40 and 50mph.Under 40 its not there and over 55 seems ok too.It doesnt happen when going up hill or letting off the gas, just when I'm cruising about 45 to 50 on flat surface.Give it gas ,it goes away, back off the throttle ,it goes away.Now i do have a dent in my #3 header pipe right by the oil pan and was wondering if that my cause a weird noise.It sounds sort of like when you tap on an exhaust pipe and have a ringing effect.I do have a vetter fairing and you can hear it real good when you put your head close to the tank while going 45.has anyone ever experienced this sound before? I have ran over 8000 miles like this and it doesnt seem to effect the bikes performance at all it just sounds annoying.Please help if you can.Can a dent cause this noise????It sounds like it's coming right up out of the fairing.
 
My guess is that it is a harmonic that sets up at around 5000RPM, not under load, and at a specific RPM range. It is doubtful that the dented pipe is causing it, however, I have heard of stranger things. If you've run it for the last 8000 miles that way and nothing seems to have happened, I wouldn't worry about it. I know that mine sets up a whirr-ing noise at about the same RPM range and the only time I can hear it is when I've moved to the queen seat to stretch out a bit on a long ride. If it were major, you would have posted differently...a long time ago. \\:D/
 
Good one chef!!! I dont think it's the wind. It's more like a ringing from the pipes,not a sputtering like an exhaust leak.I do have a fairing and was wondering if it is just feedback from the short mufflers.It does drive me nuts though!Would an exhaust leak make noise all the time?
