They head pipes aren't stock and weren't cut. I don't see any steam buildup on the pipe where the mufflers join, but an air leak could always be a possibility. I think I'm gonna do like you say, ride it and see how things go. How often should I check the plugs? After every ride or after a certain amount of miles?Popping can also be extra gas combusting in the exhaust. There also may be an air leak. If you cut off the mufflers off an 80-82 set of pipes there is a vent hole at the top next to the pipe that can pull air into the system. You need to ride the bike and do plug chops to see with your jetting needs are. Your jetting is very rich as you now have it.
