1983 GS550ES Fuel Delivery Issue

[rphillips]

The old GS's were pretty cold natured, needed choke to get going even in summer. Many, in my area, would go up a size or 2 on the pilots, just to make them start easier with less choke. I don't remember any adverse effects.

I agree with rphillips, I don't think the pilots are the smoking gun. The bike might run better with the 40's. Have you done a proper strip and clean of the carbs yet ? Are you absolutely sure that nothing is holding the slides up ? You have a very nice bike, hopefully you can get it running nice.
