After going up a large hill at about half throttle, then hitting the throttle pretty hard as some have suggested to properly seat piston rings during break-in, the engine pulled SIGNIFICANTLY harder on the level terrain afterward and the exhaust noise gained a much louder "pop" rather than a quiet hum. Is this the sound of compression increasing or some kind of muffler break? The gasket checks out OK and the oil dripping out the bottom of the muffler has suddenly stopped. thoughts?
