If it's tuned right, it should pop. Not all the time, just crackle a little sometimes.  But if it's excessive and you have an FMF pipe, I'd check the pipe before I fiddled with the carb.   They usually use a spring-seated header, and that joint wears during use and can leak too much.  The mid pipe is held into quite a few of them the same way, and the joint in the middle can leak, too.
