I wanted to thank everyone for their help. I took it to the Yamaha Dealer today and they said everything seemed to be fine. The bike idles great and the valves do not need to be adjusted. They did adjust my throttle, I guess there was not enough play in it. It did help with idling, no popping during idle. I drove it home and it continued popping. I thought about it for a few minutes and decided I do not want to jet it. I decided to put the stock mufflers back on. The dealer told me to run the PMS at 2 turns with the stock mufflers. It doesn't pop at all now, so not sure what the deal was. Thanks again!
