    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.

Ok, so I used to be on this forum. I had a gs550 that I could never quite get right but you guys were very helpful and cool. Then I bought a house and decided I couldn't have two "fixer uppers". Just last week I found another GS. This is a 850 shaft drive. I have always wanted to go on a motorcycle tour. This bike seems really clean and well maintained with a new stator and a clean title and it was cheap $750 because it flooded and died once it warmed up.

My friend came by yesterday and we pulled the carbs off. (much easier on the 850). Look what I found! These are the two outer boots from the airbox. Have you ever seen this?

They are both melted! The Diaphragm was frozen, which is why it was flooding. We cleaned the carbs anything else I should look for?
 
Yep, seen it a number of times. Usually due to back firing into the airbox and igniting. Replace all of the boots and do a complete strip and dip of the carbs. Don't forget to get them synced properly after the cleanup.
 
Looks like the ill effects of the over use of spray carb cleaner or starting fluid.
 
Seen a few like that. Congrats, you found a great deal because of a simple problem with an easy fix.
 
What is the Aussie starter fluid called....Start ya Bastard?
Frozen diaphram and burnt manifolds are serious neglect. I would check the valve clearances as well.
Welcome back.
 
Frozen diaphragm? Do You mean a seized slide? If yes it is a a very dirty and corroded carb
 
Some times the slides will become glued down inside the carb bore from gasoline varnish. If that's the case then heat up the carb body to soften the varnish and the slides will come out. Keep chemicals off the diaphragms as much as possible.

Regarding those melted boots, that's the first time I've seen the evidence. Like the others have said it's most likely the effects of spray ether.
 
It's from Maryland got a Maryland title and everything. The guy just moved here and couldn't find a job and sold the bike.
 
Thanks everyone. What is the part number for those boots? I am a bit confused at looking at the diagram
