On the right side of the bike (right side when ou are sitting on it) just above the rear brake lever behind a small circular plate. remove the plate and the oil filter is inside (you will easily see it). Warning---on these bikes you have to drop the front exhaust header and right floor board in order to change the oil filter unless you install a after market oil filter relocation kit. If you plan on changing your own oil it is highly recommended to install this relocation kit.

Your plugs are in the top of the heads. Either in the center or in just offset from center leaning outward.
