    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...

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.

Leaky #2 Carb... Can't Seem to Plug It.

Fiddled around with my project today (1981 GS1000G) after letting her sit for a month or so. Off the bat, the carbs leaked like crazy. Not overflow, but out of where the bowls meet the carb. No biggie. Figure the gaskets dried out. Took the carbs off, bench synced 'em for ****s, re-torqued all of the float bolts, and popped 'em back on the bike. Much better. 'Cept the #2 carb still has a small leak. Fack. Pulled the carbs back off, un-bolted #2's bowl and cleaned all mating surfaces. Added a little silicone grease to the gasket, both sides. Re-bolted and torqued. Popped 'em back on the bike and... Leak is down to a slow dribble.

I'm not quite sure what's going on with the #2 carb. In theory, it really shouldn't be leaking... I'm going to pop the carbs back off tomorrow along with the gas tank and do a leak down test off the bike so I can really get my eyes on what's going on and where. Until then, do you guys know of anything that causes this sort of issue, things I should look out for? Float levels are good.

Thanks for any insight.

Cheers.
 
Thanks for the heads. I'll be sure to take a look at the tubes.
 
Bad petcock sending gas down the vacuum tube into #2 carb maybe?
 
Check you float levels,the fuel level should be below the gasket surface.

This was the ticket. Float level was off in #2. Adjusted and she's leak free... Having carb tuning issues now, but I'll open another thread for that.

Cheers!
