Yes, compression should push your finger away although its not a very accurate measure.

Your going to need to remove the head cover to make sure the cams and tappets look ok then remove the head to check the valves and piston.

could be that the compression is so low that the bike is not able to draw in enough air/fuel mix to keep the engine going. by using easy start or a similar product you're forcing fuel into the engine & so it's starting. have you tried doing a compression test?
