Rejetted carb. Runs good but at higher rpms I hear a clanging noise. Almost like a chain sound. Chain is good. Brand new. We're talking 7500+ rpm.

I'm thinking fin ring.
			
			
			
				Didn't know they existed. I will research. Thanks!
			
			
			
				It almost sounded like pinging. 
			
			
			
				There's still a bunch in there.
