    Need help with tuning carbs. pleaseee :)

    Hello everyone,
    I just got this beautiful Suzuki GS750L from 1981 But the bike doesn't run well...
    By the power of this community I think I find the problem...
    Previous owner has done few upgrades/customisation. He has fit custom made exhaust (sounds nice) 4 into 2 and change the air filter (Right now covered with tape) when I removed the tape is getting worst... He has made all those mods but he haven't tune the carbs... I presume here is the problem... I need to tune the carbs
    And here I need your help
    I want to keep this exhaust and filters. So if you can advise me what needs to be change, how to do it, jet sizes, etc. I will appreciate that
    If you need more information please ask.

      Buy a Dynojet kit and get real pods, not Emgo or similar cheapies. APE sells some decent pods that are cheaper than real K&N's if your budget it tight.

          It will also help if you can find some mufflers.

              There is a Carb/Fuel/Exhaust forum farther up the forum listings specifically for questions such as this. Look there and you may even find what you need from previous posts.

              +1 on the APE pods. I have had K&N pods and the APE ones. They are indistinguishable in my experience.

              Meh, mufflers are often overrated. They might make the tuning a bit easier, though. Considering how small those tail pipes are OP may have enough restriction as it is.
