when you add an exhaust and filter everyone says to up the main jet, but why not the pilot? it still feeds the motor if only at idle to 1/4 throttle... shouldnt you need to do them both? just trying to understand it
why not a bigger pilot jet?

Many times exhaust systems will require the same if not less fuel at 1/4 throttle. Your pilot air screw will have enough adjustment to accomodate for the exhaust in most cases. Different pilots can be required on low-mid pipes at low elevations. High flow intakes however can cause a need for a larger pilot, but again the air screw may have enough adjustment.
ok, is tuning using the idle and the air screw to see if you have the correct pilot a good idea? like if the idle is highest whens the screw is in between 1.5 and 2.5 its the right size jet and if its out more than 2.5 the jets to big and vise versa?
