Just guessing from looking at the parts microfiche, because they don't show you much on the oil pump page (where the filter it shown), but considering most singles put it in a side case somewhere, that's where I thought I'd look. After looking at that page, there was a secondary cover on the right case cover that isn't shown and it looked to be of the same configuration as the oil filter cover shown on the oil pump page... so that's where I'd look.
As for capacity, near the oil filler or sight glass there should be a capacity stenciled on the case cover. It will be pretty close to how much oil you'll need if you have any doubts about your internet source. This number is usually the oil capacity when the motor is completely dry, so it won't take quite as much as what's stenciled.
