    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.

Long story short -- just got a 1981 GS650E. The carbs are solid varnish. I'm cleaning them, but can't get the main or pilot jets out. Will this be a problem? Also, what else should I watch out for?

Thanks in advance.
 
Re: carb rebuilds

If they are varnished up so solidly that you cannot remove them, its a pretty safe bet they are varnished up badly enough that they must be removed and cleaned. I have had to soak badly varnished carbs for as long as 3 days to be able to remove jets.

There isnt an alternative.

There is an alternative!! find an auto repair place that has the new "ultrasonic" cleaner, faster and wont damage o-rings.

Thanks for the advice.
The pilot jet is slotted on top, so I assume it is threaded. But the main jet has a slot in the side. will this just push out from the inside of the carb? There is a brass pin in the body that lines up with the slot.
 
The main jet pushes out through the top of the carb once the slide and needle is removed, not from underneath in the float bowl.

Boys - Boys - Don't fight!

OK, so far so good. I've got the four main jets out and three of the the four pilot jets (soaking the stubborn fourth).

Just one more question: The Clymer book says that the main jets have o-rings - but I didn't find any! Is this a misprint?

Thanks so much for your advice!!
 
Probably

Probably

I think it's probably a mistake...(I've never seen a main jet that had an "O" ring). The Clymer books are pretty good but I've found a couple of obvious errors in mine. :?
 
There are some press fit main jets that do use "O" rings, but none of the GS models with Mikuni carbs use "O" rings on their main jets. I think you found a printing error. :-)
