Preheat gas grill to medium-high heat.
Pat chicken dry with paper towels.
In a small bowl, combine oil, cumin, garlic powder, onion powder, kosher salt, paprika, oregano, cayenne pepper, and black pepper. Thoroughly coat the outside and inside cavity of the chicken.
Place half-full beer can (opened) into the disposable pan.
Lower chicken onto beer can so that the chicken is sitting upright.
Turn off one grill burner and place the chicken over this area, for indirect cooking.

Allow the chicken to cook with the lid closed. (Do not open up the lid for at least the first 45 minutes while the chicken is cooking.)
At 1 hour and 15 minutes, use a thermometer to check the temperature. Insert the thermometer into the thickest part of the chicken, without touching the bone, the thermometer should read 165° F.
Turn the grill heat up to high and allow the chicken crisp for 10 minutes longer.
Carefully transfer the chicken out of the grill and allow it to rest 10 minutes.
