    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.

How critical is 1 airscrew?

Well, I finally got through the cleaning & gasket/o-ring replacements on my GS650GLX. One problem remains - #4 carb airscrew is frozen in place. I even took it to a vintage-bike shop in the Detroit area, and he couldn't budge it. The alternative at this place is to have it drilled out, but the shop owner advised strongly against that. His point was he couldn't guarantee the carb body wouldn't be damaged, and it appears the air screw is frozen in a 3/4-turn out position. Since it only controls idle, and with three other carbs adjusted properly, he felt the the little gain wasn't worth the risk (unless I had an xtra #4 carb body).

My question is: do you all agree with his statement? I am tempted to just leave it alone, but would appreciate any insight you folks may have.

Does it idle on that cylinder???

Does it idle on that cylinder???

If not you might want to try to fix it.
If it works OK, why bother?
 
tkent02, I haven't got to the point of reinstalling on the bike, so I simply don't know. It wouldn't idle more than 10-15 seconds before stalling out (unless I gave it throttle) before I stripped the carbs of the bike because two of the carbs were leaking fuel badly.

Your point is well taken, though. I will reinstall once I get the new pilot jets, and check that. I think I will buy the "view-plug" (can't remember the actual name off-hand). I don't have the money for manometer right now, so I will bench-sync, reinstall, do the highest rpm method, and fine-tune in a month or so. Am I making sense here?

No point in spending what you don't want to at this point. Chances are it may have been adjusted about right way back when.
If it doesn't work too well you can always look on ebay for a carb body.
 
Will these carbs work on an 82 GS850G

Will these carbs work on an 82 GS850G

Hi All;

I trying to figure out whether the following carbs will work on my 82 GS850G (Mikuni BS32SS, ID# 45160).

1) 1980 GS550
2) 1982 GS1100
3) 1982 GS1100E
4) 1983 GS1100E

I ask because I want to get a set of carbs to work on, but I want to be able to use them on my bike.

Thanks in advance for any info/advice.

Charles...
