Combine flour, cornstarch, salt, and pepper in a large bowl.
Toss chicken to coat evenly.
Heat oil in a pan over medium fire until the temperature reaches 350 degrees F.
Add chicken wings, shaking off excess coating, one by one into hot oil and cook until crispy and golden brown, about 8 minutes per batch, flipping once. Repeat with the remaining chicken wings.
Meanwhile, stir together honey, Sriracha, ketchup, and lemon juice.
Toss fried chicken wings into the sauce and gently toss to coat.
Serve with a garnish of toasted sesame seeds.
