I would be pulling that side cover and having a look at the oil resevoir compartment inside. The only way I could imagine that motor is getting oil is if Apollo has drilled from the resevior through to the oil pump outlet which is cast directly behind it.
It wouldn't surprise me if the Apollo assemblers don't realise how the oil feed works in this motor. Lifan doesn't supply coolers or the lines so the motor comes from the factory with the cases plugged like you have. If they just bought a shipment to keep up with the cc race, thinking it is the same as the previous engines, they just may not know. Big blunder if thats the case. I know it has happened to some dealers in Europe.
If it doesn't have the oil feed internally modified then there are a heap of people gonna be pissed real soon! No oil to the head or the crank.
