when i down shift it backfires, only when I downshift it does this.  I sprayed carb cleaner around the carb, and did not hear a change in idle.  Thank you, Bucky

Check for leaks where the exhaust connects to the cylinder head. Check spark plug to see if the combustion is rich, lean, or correct. You may need to clean and rejet if required especially if the air filter/air box and exhaust is not stock or if the stock exhaust has been modified.
