Lucio: If you really want to drive yourself crazy, go to the med supply store and buy a stethoscope. Pull the "for humans" cup off and replace it with a hard copper tube of about 1/4 inside diameter. Length doesn't matter. Find a small rubber protective cup made for wire cabinets and cut a hole in the end. Put that on the end of the tube that you will place on the engine. Warm up your engine and then start placing the tip of the metal tube at various places on the engine. Listen at idle and then at 1500 rpm and if you don't mind reving the engine a little more, at 2000 rpm. You can hear about everything that is going on in quite some detail. It will scare you at first, but the stethoscope is an amazing tool used right. I have never tried doing this at speed, but don't see why it wouldn't work assuming a very low traffic highway. Some mechanics use a long screwdriver held to one ear. That works but it will leave a mark on the touch points given the vibrations of the Harley engine.
You can find a valve tappet that is not working like the others in a minute. You can find air leaks in the intake system. You can hear piston slap if there is any. Multiple carbs are easy to balance by making the sound of the air rushing into the intake sound alike throughout the carbs. ......... BC

I keep hearing a pinging or rattle on mine too. Thought it might be spark knock but it does it more when I'm letting off the throttle than when I open her up. Or sometimes when I'm just cruising along. My buddies say just ride. I do like the idea of a louder exhaust as the best fix for the situation.
