A B737 departed on the sbeg ilkup SID; kokru transition; but the 2;000 ft turn constraint was not in the FMS departure programming and additionally chart ambiguity does not specify which departure track to follow after an eastbound takeoff.

Narrative:
We were cleared the ilkup departure with the kokru transition. During the preflight route/FMS review; we noted the departure note 1 mandates runway heading until 2;000 ft; but the FMC is programmed for an immediate turn back to mns. Because of this discrepancy; I briefed and flew a departure in runway heading/heading select with a manual turn after 2;000 ft to comply with the restriction (we were eventually cleared a left turn direct ilkup). Also; there are two ground tracks depicted; one which proceeds back to mns and one which directs a ground track of 280 degrees to intercept the 330 degree radial to ilkup. However; the narrative does not differentiate. The departure procedure needs to be clarified to specify which ground track to fly and the FMS needs to then be programmed accordingly. In the interim; a note to flight crews should be placed on the flight plan from sbeg clarifying the procedure to follow.
