What’s Up with my loud ZG127S?

[stealthelf86]

So my ZG127s' suddenly running loud, and I can’t figure out why. I thought it was the muffler, so I replaced that, but it didn’t help at all. I’m still hearing this annoying exhaust leak, and it’s being a pain to start. I’ve swapped out the fuel filter and even upgraded the fuel line, but no luck.
Anyone dealt with this kind of thing before? I’m seriously losing my mind over here! Tsk, tsk.
