Reply To: Jetting a GT125R – 2017 ..?
At pilot 30’s , what is the mixture on the carb how many turns is it ?
It could be your climate and altitude where you live at , but here in UK , 15 pilots on the 125cc is the gold standard. The 4-7k rpm flat response is improved by ofcourse fine tuning the slide needle with larger main jets (1 size up front and rear main jets)
