Carb cleaning 83 GS850G

[Guest]

Just picked the bike up tonight, it has been sitting for a decade at least, it needs the carbs gone through badly. I never looked under the tank to see what was involved, how many hoses come off of the tank just so I know? and when I dig into the carbs, besides the vaccum diaphragms, what else should I check out? thanks guys for any info!

Two hoses on the tank(vacuum and fuel) and two bullet electrical connectors.

As for the carb rebuild:

You might want to look at adjusting the valves as well:

Uh, you might want to take the fuel level unit out of the tank when you clean it.

I have the 82 GS 850 G don't be afraid to take everything off and go through the carbs it's very straight forward and easy to do. I would buy a new O-Ring Kit the rest should be easily cleaned just follow the directions in the garage section GS resources. While the carbs are off you should probably do a valve adjustment with everything apart make sure the rubbers on both sides of the carbs are soft and won't allow air leaks. good luck

No problem with flipping the tank upside down.
