I have a 96' but I am pretty sure that nothing has changed. Bend down on the low side (battery side) of the bike. On the bottom of the frame is a hose that attaches to a knob on the frame. The hose should be held on with a hose clamp and once loosened and pulled from the frame will drain the oil. I just looked at my father-in-laws '06 sportster and his drain plug (for the oil tank) is a hose underneth the engine that is plugged with a plastic stopper and then hose clamped. Loosen the hose clamp to pull the stopper to drain the reservoir tank. The engine drain plug is on the left side of the bike toward the rear of the engine. It's about a 17mm head bolt and that'll drain the engine's sump.
The drain plug is under the engine, near the kick stand.
The gap setting is 0.034 to 0.037.
on bottom of trans. case. kind of hard to reach
That plug is the drain plug for the primary and transmission oil supply.
Check out the pictures at the following website. The drain plug is toward the rear of the bike, in front of the rear tire. http://www.harleydavidsonmaintenance.com/sportster-oil-change.html
There is a Hose with a Clip attached to the Left Side of the Frame underneath the Primary Cover. Remove the Clip and Pull the Drain Plug in the Hose..
My Sportster has a drain hose that attaches to the oil tank and crosses over to the opposite side of the bike. It is hose clamped to something like a lug on the bottom of the bike frame.
Bottom of the engine on the oil pan.

The transmission drain plug is located on the left side of the bike as you are sitting on it, right behind the front foot peg. It is a 16mm hex head bolt.
Follow the hose that goes to the frame from the oil tank. Loosen the clamp and pull.
