I know its a stupid qeustion but where exactly on the motorcycle is the air screw and throttle screw. I have a 2007 Suzuki rm125.

The air mixture needle valve is on the Carb. Throttle screw as you call it, you might be referring to 1- throttle adjustment at the twist throttle hand grip. 2- At the top of the carb is a throttle cable adjustment 3- some times somewhere between the twist grip and the carb there is an adjustment.4- there is also a idle adjustment at the carb.
