Reply To: Bike doesn’t have power – Hyosung GT125
Hi! I did it just like you said and it bumped up to 11 kg/cm2 on both cylinders. I just have to open them and see inside and look for scratches or the state of the rings right? If it is just the rings, where would I find them? Hyosung doesn’t have anything for this bikes here in Spain.
It is easier to find used pistons and cylinders on ebay. Some sellers and myself regularly list them there because Hyosung Korea is not making parts for any bike before 2019
So they only make parts for current models now (Gv125-S EFi 2020+ , GV300, GV250DR , GV650PC now)
However , I am still busy studying and researching different rings , until i can find one that will fit GT125 , then i will list them on the shop but for now, our best hope is used parts. Lets hope it is just cylinder or head-gasket leaks.
