I know this has been talked about already but I didn't find anything that answered my question, so here it is. I have an '81 cb750K. It runs pretty good with 19k+. I've only had the bike for a few months now and have put 1100 miles on it. I've noticed that the popping in one specific muffler (there are 4) is popping a lot, especially around 4k RPM. It does it on a constant accel and decel. Do these symptoms sound more like a carb issue or a leak? Any help is appreciated. Thanks.
