I know it is in here somewhere,but what is the stock setting for the air screw mixture on a 1980 GS1100E

It doesn't really matter, around a turn or so just to get it going. They need to be adjusted individually for highest idle speed. -
The bike runs great it takes forever to warm up.Comment

The stock setting was probably just over one turn, maybe 1 1/8.
However, if you want something that works, start with 2 or 3 turns out, then tweak from there to attain highest idle speed.

If you haven't been though the carbs in a while it's well worth the effort to dip them and replace all the O-rings inside plus the intake pipe boot O-rings as well. After that, set the screws to 2.5 turns from lightly seated and vacuum sync the carbs followed by adjusting the mixture screws to achieve the highest idle speed as mentioned already.Ed
To measure is to know.

I don't have o rings on the intake boots,but my clamps are maxed out.Should there be a little gap on the clamps when tight?Comment

The thing about the bike is it runs great when it is up to temp,but it has a small stumble below 2500 after that hold on.The bike is all stock except a uni air filter that the PO put on it.I think I should get a stock air filter for it to ritchen it up a littleComment

The clamps being completely, or almost completely, together is normal.1983 GS1100E, 1983 CB1100F, 1991 GSX1100G, 1996 Kaw. ZL600 Eliminator, 1999 Bandit 1200S, 2005 Bandit 1200S, 2000 Kaw. ZRX 1100Comment

The thing that bugs me about this bike is that I found it sitting in a garage for the past 25 years and I know that sitting is a bad thing but it has only 7500 miles on it.Do you guys think since I am riding it every day I am going to find promblems with it.Read my past posts I did work on it and thought I did everything right.Comment

Sounds like you are very close if it only stumbles when cold. Just a tiny bit lean for whatever reason, maybe too lean from the factory. If that filter does not fix it, look at raising the needles and adjusting the mixture screws.
My 1100E sat for 23 years, cleaned the carbs and electrical connections, brakes and tires, have had no problems with it at all.Comment
