    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.

This has been a curious thought since i got the bike. Is this a p.o mod. It doesnt bug me or cause any problems just wanted to throw this curious thought out to the gs world.

The little holes are not evenly-spaced enough to make me believe they are "factory", the large hole is DEFINITELY not stock. :eek:

so even the little holes are not stock, the bike sounds good, and you dont really notice the hole unless your really looking cause its at the angle towards the ground. what do these bikes sound like with out the modifications cause mine sounds really good, kinda ninja like but not at the same time
 
The only stock hole is the one in the middle.
 
not ever really looking at another stock 550 exhaust i wanted to ask the question that had been in the back of my mind, never would of thought that the little holes where from the p.o as well

As I mentioned, if it were done at the factory, all the holes would have been evenly-spaced.

The L mufflers and some of the later E bikes had some extra holes at the back. Depending on the bike, sometimes the center hole was open, other times only the outer holes, some other bikes had them all open.

This is on my wife's 850L

Previous owner of this exhaust drilled holes in the center. I braised them closed and afterwards the bike sound better and ran better.

Totally agree about the large hole and Steve is probably also right about smaller holes but I have seen the smaller holes done like that before on GS's and other bikes too. Have also seen it neatly reversed and a ring welded back on but can't find it in the search
