Drain the excess juices from the pan.

Slice the pork roast and pull apart the meat (trimming the fat) and place back into roasting pan.Prepare the BBQ sauce: In a large bowl, mix the cider vinegar, water, ketchup, dark brown sugar, salt, and red pepper flakes and pour over pulled pork, stirring to make sure all pork is covered; cover with aluminum foil.Place pulled pork back into the oven (still at 325F) or in pan on grill and cook for 1 1/2 hours, stirring pork and BBQ every 30 minutes.
