Proper oiling of the air filter will fix a lean condition. I have been working on my 82 GS1100GL since I bought it in august trying to get all the proper maintenance done. The charging system is working perfectly now, carbs have been torn down and properly rebuilt, air box boots replaced, air box sealed, new intake boots and o-rings, valves adjusted and carbs synced. Bike was still running a little lean and had a slight stumble in the mid range.
It has a 4 into 1 Vance and Hines exhaust and a Uni filter other than that it is all stock. So I shimmed the needles to fix the mid range and I ordered some 120 mains for the lean condition. Well I ordered the jets from Boulevard Suzuki about three weeks ago and I still don't have them so in the mean time I have been reading a lot of threads. I have never used Uni filters before and i could have sworn that I read one post that said to not oil a Uni filter so I left it dry when I did all the maintenance. I decided to use the search function and wouldn't you know it they should be oiled.
I ran to the shed pulled out the bike and cleaned and oiled the filter. Threw it back in and fired her up. I could instantly tell it was running richer. Actually to rich at idle so I turn the idle mixture screws in a quarter turn and went for a ride. The bike is still to rich in the first quarter of throttle so I'm going to turn the idle mixture screws in another quarter turn next chance I get. That would put them at 2 3/4 turns a full 1/2 less than what they were before oiling the filter. I can also hit the start button now without applying any throttle once the bike is warm. Before I had to crack the throttle just a touch to get it to start. Full throttle still feels like it could use a little more. However I think I can get away with using 117.5 instead of the 120 mains.
