    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.

Replacing Carburators

Reading through the mass of information in these forums there does seem to be ALOT on carbs. Rebuilding, swapping, performance and the like.
( Still have 200 or so pages to sift through :lol: )
What if I wanted to replace mine. 82 GS1100GL. What would I look for?
I'd like to see a performance gain, up the economy, and improve servicabilty.
Any thoughts?
 
the slingshots are easily serviced, expect to go through jetting hell though.

and if you want better fuel economy, keep dreaming
 
Hm.

For more performance, people generally put on a less-restrictive exhaust system (which also means a louder bike), which often means putting in wider jets.

However, the price paid for higher performance is lower gas mileage.

I don't think there are any carb mods you can make to get better gas mileage, unless you want to lower performance. Probably the best way to improve a GS1100GL's gas mileage (other than swapping in a GS850 engine) is to stop twisting the throttle so damn hard... :D
 
Assuming the bike is stock (mainly air box, carbs and exhaust), your best bet is make sure they are clean and adjusted properly. That will give you the best combination of performance, serviceability and economy IMHO.

The next possibility up would be to replace the airbox with pods and the stock exhaust with a 4-1 unit to let it breath better. You will need to rejet the carbs to match the better air flow. That can go relatively smoothly or (more likely) turn into a long tedious process, but it can be done and the results can be very satisfying. Do a search on the threads here about it. You will gain some performance but lose economy. You will gain servicability because you will learn so much about them during the rejetting process. :)

Lastly you can replace the carbs with something really radical - look in the Performance Mods section to see some of the possibilities. The sky's the limit with these bikes - carbs, cams, pistons, even turbos...
