    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.

gs550 exhaust question

I'm running a stock 78 gs550E (vm carbs). I was thinking of changing the stock pipes to stock pipes from a L model or a 1985 550 because they are shorter. I don't want to mess with the jetting since I just got the bike running smooth. Will the shorter pipes work in this case without affecting the jetting?

Your going to need to test it to find out. Make sure everything else is tip top before making a jet change. Clean air filter, carbs sync'd, no intake leaks, etc. Otherwise you will be rejetting to cover another problem and then you'll be really screwed.

if the bike is essentially stock I suspect you won't need to change anything. Airbox replacement wit pods generally requires more work.

What you should worry about before jetting is will the pipes physically fit your 550. The 85 550 engine is a similar but different engine, and the frame is nothing like your 78 E. The L models also use a different frame than your 78 E. You will probably find this is not going to be a simple swap job. Keep us informed
 
yes, thats what I was wondering myself.. I was figuring since the engine blocks were the same that they would mount in the front. And on the sides I could custom fit it somehow. Seems like the L model from 77-79 may work. Gonna get a cheap set and try it. thanks for the replys.
