In the small hole on the stator cover you should see the T sideways. The piston will be at TDC. If the cam chain is off it doesn't matter about compression or exhaust stroke. Get the chain on the bottom gear and the top gear like this:
Be sure that the cam lobes are DOWN.
Unless you have removed the stator rotor and installed it 180' out there's no way the piston will be at BDC with the T mark in the hole.
