Remove inspection plugs on side cover and turn crankshaft counterclockwise until in small hole the "I" lines up with the mark on the case. Your piston should be at top dead center (TDC)

The little round mark on the cam gear should be straight up from top of cylinder (looking level with the top)

You can look at the 660 service manual too under Engine section. Go here to look at the manual for pictures and step by step: Modded Raptor - For the rider that can't leave anything STOCK!
