Why does the bike pop on deceleration?
The bike is jetted very lean from the factory. You can enrich the idle mixture by removing the pilot screw cap and backing the screw out 1/2 to 3/4 turn from its factory setting. (The pilot screw is located on the engine side of the carb, in front of the bowl, on the bottom. It is underneath a plug, which must be drilled through to remove.) Note that it may be illegal to tamper with carb settings in your state. Note that this symptom can also indicate an exhaust leak, so check all of the exhaust connections first.
