Add chicken drumsticks to a large resealable plastic bag (skin on or off as desired). Combine ½ cup maple syrup, ½ cup chili sauce, ¼ cup apple cider vinegar, 1 tsp minced garlic, and salt. Pour over drumsticks into a bag. You can also do this in a large bowl, and stir to coat, but it is easiest in a bag.
Seal the bag and turn to coat drumsticks. Place in the refrigerator to marinate for 2-8 hours (I marinated mine for just a couple of hours).
Preheat grill to about 400 degrees F (I had 2 sides on, and one side off so I could move them to indirect heat if need be). Either grease the grill with oil or non-stick or spray a piece of tin foil with non-stick spray and place it on the grill over the heat (*see post for additional explanation). Place drumsticks on the grill, and cook, turning every so often, for 20-25 minutes or until meat starts to fall away from the bone. Keep an eye on them so they don't burn! Move to indirect heat if need be.
While drumsticks are cooking (or you can do this ahead of time if you need to), combine ¼ cup maple syrup, ¼ cup chili sauce, ⅛ cup apple cider vinegar, and ½ tsp minced garlic in a small pot. Bring to a low simmer over medium heat and cook, stirring often, until reduced and thickened (about 10-15 minutes). Turn off the heat and keep warm until the chicken is done.
Brush drumsticks with thickened glaze before serving.

Notes
Store: Store this dish in an airtight container in the refrigerator for up to 3 days. Allow the chicken to cool to room temperature before putting it in the fridge. Refrigerate within 2 hours of cooking it.Freeze: Maple glazed chicken drumsticks can be frozen after cooking them very easily. I'd recommend removing the meat from the bone and shredding the chicken. Put the shredded chicken in a Ziploc bag, and store it in the freezer for up to 1 month. Defrost overnight in the refrigerator and reheat in the microwave or on top of foil on the grill.
