    Another jetting question

    On the current GS1000 build I have it finally running. I completed the koolaids kid idle adjustment tutorial and it's perfect, I also synced the carbs today and they are dead on, actually better than my other bikes. I think the bike needs an increase in jetting. When driving if you give it gas it stumbles it continues to increase sound and RPMs but zero increase in power with the rpm increase. If I pull the choke while running it's better but still not perfect
    the main is 115, pilot is 40 and the air jet is 170

    i have a set of 140 air jets several pilot jets 42.5 and 45 and different pilot air jets 160-180

    the mods on the bike are stock air box, UNi filter lightly oiled and a MAC 4:1 with competition baffle. I know inside I should of increased the jetting but I just wanted to get the carbs running to see how the engine ran.

    any advice on the jetting is appreciated.

    Also valves are good, spark plugs seem to have a hot spark and the plugs are gapped properly

    Try a 120 or 122.5 main jet first.

      What about the other jetting Steve like the pilot or air jets do you think I should keep it or change it also? Do you think it's the jetting? I'm 99.9% sure it is he problem, it revs just fine idles just fine but when riding it's like there is a parachute behind it but the engine keeps revving
