Default older 50 atv

I just bought my son a used 50 atv. The serial # is KMAA11A001101359. The previous owner said the only work that's been done to it has been a ring job. He disabled the oil injection and ran a mix instead. It seems to run fine but the spark plug appears to be slightly wet and dirty. What is the correct plug # to replace the old one and what ratio would you recommend on fuel mixture(40 to 1,32 to 1) as I don't plan on fixing the oil injection yet? Could you also tell exactly what year it is.
