I have a 2006 TTR50 for my son. He is currently running a BBR exhaust, I recently purchased a GYTR air filter and jet kit and am having some trouble tuning. I am using the 72.5 main jet and adjustable needle set on the 5th setting. The instructions indicate that the pilot screw needs to be adjusted to 1-1/4 turns out, does anyone know where the pilot screw is located? I am assuming they are refering to the air/fuel mix screw.
