Motorcycle Repair: serviceing my bike, softail shocks, oval plate

Question
where is the drain plug on the primary and on the trans on a 2002 fatboy and how much oil does each take thanks

Answer
Primary drain plug is at bottom rear of primary and its a #40 torx bit to remove it.  It holds 26 oz.  Fill it through the inspection cover housing (small oval plate) and use a new gasket #60567-90C, $3.25.  Trans. drain plug is a 5/8" hex with a hole for a 1/4" allen in the center.  It's up in between your softail shocks. Don't crossthread it putting it back.  If the o-ring is flattened or frayed replace it with part #11105.  It holds 24oz. of tranny oil but only refill it with 20-22.  There's always some clinging to the case and gears.
