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.

    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, got problem. Cleaned the carbs of my GS850L, thought all was well, but now it is only running on #1 and #4. All carbs are getting gas, so it would seem, and it seems that two and three firing. Any suggestions?????:sad: ](*,)
I'm quite sure the coils are firing, my hair is still on end, well at least shocked:lol:
 
Regardless of what you're quite sure of, you should swap the coils for a sanity check to see if the problem moves from 2 & 3 to 1 & 4.
If no difference:
You're sure 2 & 3 are not combusting, so have you checked plugs 2 & 3 to see if they're wet? If not, then fuel is not being delivered.
Of course it could be merely coincidence that you mistakenly botched carbs 2 & 3 during the cleaning. Botching a cleaning happens to anyone who's done enough of them, eventually - nothing to be ashamed of. Just do it again.
Your vacuum line may be sucking fuel but that would affect only one of the two - but, of course they may not have the same problem.
And then there's my favorite: air leaks. Are you sure there are no air leaks for any of the boots for carbs 2 & 3?
 
:| I have rebuilt kits, have not used them yet. I have not check the plugs to see if they are wet, Duh on my part:oops: . As for the coils, they are some what idiot proof, but I can engineer something. I will give these things a try. Thanks for this info. Will post my finding.:-D
 
Check for spark on the failing cylinders. If both are a no go you either knocked a wire loose, have a bad coil or have a bad pickup on the crank trigger.

What year is it? Is it points?
 
If the coil wires are "idiot proof" he's got a 80 or newer, so electronic ignition...
 
Were the cyls firing before the cleaning of the carbs? I would check the sync on them. I believe that is why one of my cyls wasn't firing in the first place, after you check the other things suggested of course. Good luck!
