Philippines BBQ w/ Sprite

for every 1 kg of pork you need:
¾ cup soy sauce
¾ cup brown sugar
¾ cup ketchup
¼ cup lemon juice or less
1 cup Sprite or 7-up
5 cloves garlic crushed
⅓ tsp salt
⅓ tsp pepper
⅓ tsp msg
On the video I said to put the meat on the grill for 40 minutes but after about 10 minutes I turn my grill off because of the sugar in it, it burns faster so please watch it.
