    With the size 15 pilot jets in I was having to turn the mixture screws about 4 to 4.5 turns out (almost coming undone) just for it not to feel laggy and when I re-engage the throttle after letting it decel down while riding in a gear it can bog out for a second or two before restoring power. With the 17.5 pilot jets in I have been having much easier cold starts, and less problems with the bogging out but itโ€™s still their just very slightly. My main jets and everything else are still the same. Yes the stock airbox is on the bike but a better air filter is in the airbox.

    As to your very first point, the bike seems to be happier with these 17.5 screws in, I just need help with fine tuning and the sync screw at the bottom has been changed by someone else who had the carb and I think itโ€™s been set wrong. From my knowledge, turning that screw will move the plate on one of the carb butterflies. I could be wrong but thats what I know of right now. I just want to see if anyone has a video and or audio file of a Hyosung GT125R 2016 idling so I can hear the correct exhaust beat pattern and change the sync and idle adjustment so it is better.
