How much air in the front and the back tires for a 2003 HD Dyna Lowrider are required

Your engine is a dry sump engine, the oil drains at the TANK and not at the engine.

The oil tank for your Dyna is on the bottom of the transmission. The oil drain plug is the one closest to the left front corner of the pan.

You can adjust it IF your bike is equipped with a carb. You may have to take the outer air filter cover off. Look at the top of the carb. Just to right of the round looking top is the idle stop screw. Clockwise to speed it up.

without a passenger is 34psi front and rear. witha passenger is 40 rear 34 front.

The oil tank is on the bottom of the transmission. Two drain plugs. The center one is the transmission drain, the one towards the front on the left side is engine oil drain.

Since you have the so called "narrow-glide" front end, like a Sportster, you would find the same fairing as used on FLHX to be huge and not good for handling (excessive bulk). It would also require special brackets. Look at the Hoppe "VanillaZilla" aftermarket kit -- not cheap! -- for your narrow glide. As far as hard bags, there are various aftermarket kits available.
