So my bike does not have the manual cam chain adjuster and have not heard a loud noise from videos I've seen of people who needed to replace but when I'm giving my bike gas I notice a slight different noise but have heard others who made the same noise, normal?
Here's a video of my bike idling, I'll have to make another of riding it.
2009 XR650L (100+k miles)
2008 Qlink XP200 (60k miles)
2006 CRF250r (traded)
