Hi I have a 2000 yz 125 and I am going to buy a pro circuit pipe and silencer for christmas. I am starting my racing career next year and I would like to know which pipe and silencer combo is the best for motocross and I hear you have to play with the jetting to get the most performance out of the pipe and silencer so could you tell me the jetting settings if you could. thank you and see you at the races next year.
