Reply To: I need help tuning / syncing my carbs!
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 it’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 it’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.
