Hello everyone!

I have a question. I recently bought a QLINK XF200. I absolutely love it! I think the quality is WAY better than my LF200GY-5 was. It is a blast to ride! I was wondering about one thing. There is a ticking noise that comes from the engine. The bike runs like a CHAMP and rides very nicely, just has a constant ticking sound. Any ideas what it could be? Is it normal for this bike? I know my Lifan had a similar ticking sound....
Thanks!
