Can someone tell me if my 08 outlaw 525s is normal loud or problem loud. I had a friend point out today it sounds like rod know but all outlaw 525s I search are loud and there are a million people who say they naturally sound like gravel crushers. I don’t want to do damage by riding. I already checked primary nut. I can send you a clip if you know what your listening for.

There is a nut on the right side ( when sitting on the quad )  that has been known to come loose.  Do a search on here. It is left hand thread.  If you pull the clutch in and it gets quiet. then it is not the nut usually.

RFS motors are pretty loud motors in general, especially when theyre cold. 

As Distraction said, there is a left hand aluminum nut that will back off that can make a bunch of noise.

Also, the exhaust flange tends to leak and make a tapping noise (I had mine welded to the exhaust).  On mine, the exhaust gasket burns out every few months and I have to replace it and it'll make a sound like knock.  I keep a few spare gaskets in my garage... in fact I suspect mine is leaking again.

The primary nut was the first check I did and exhaust seems tight. I have a video it may be just a normal Ed’s loud but I don’t know and need someone to watch the video that would know

If you Google "Noisy RFS Engine" you'll see a bunch of posts. They are just noisy.

If you let the idle drop below about 1700/1800 rpm, the auto decompressor will knock, but that goes away when the rpms get above that.
