    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.

Advice on cutting stock exhaust

I just got a gs1100 and am thinking of some ideas to spice it up. I am interested in getting a new exhaust or cutting my stock pipes.

How does one go about cutting the stock pipes? I have read a lot on here about rejetting but can find a definitive answer. I'd like to cut my pipes near the passenger pegs then I'd put the baffles back on so it isn't too loud. I want a little noise but nothing obnoxiousness.

FYI-Everything I have on the bike is stock. Also one pipe backfires a lot right at the baffle and it is quite rusted. Would the backfire go away and is rejetting always necessary?
 
Many times the popping or back firing in the mufflers is caused by the cold air getting sucked in thru holes or cracks. The fresh oxygen mixes and ignites unspent gas vapors. I think I would be 100% sure the carbs are clean and then add whatever mufflers your gonna go with. Then see if the bike runs better, holds a better idle, and the back firing stops. You may well not need any carbs parts once all the basics are sorted out.
 
Hi,

The definitive answer is "Any modifications to intake or exhaust usually require jetting changes. The actual jetting changes needed will vary depending on the severity of the modifications."

Research the "plug chop" procedures on my little website. You can also read the Factory Pro jetting procedures. There's a link on my site on one of the carb pages.


Thank you for your indulgence,

BassCliff
