I have a 1982 suzuki gs750t that I built. The stock jet sizes were 115 main and 42.2 pilot. It has a 4-1 Delkevic straight exhaust, I acknowledge the need for some sort of muffler tip for back pressure. Pods with UNI brand filter foam inserted have also been installed. The bike currently runs on 140 mains and the og 42.2 pilots, but the idle is in the 2,500-3,000 range. What size pilots are best for my setup, and should I adjust the mains accordingly? Any information would be outstanding.
