Black residue on exhaust muffler outlet

Recommended Posts

2017 MT07 standard muffler. I have what looks like black oil specs on the outlet. Is this normal?

Yup, it's just carbon and condensation (black water) cleans right up with some WD-40 and a rag.

You'll see this on ANY exhaust whether it's a car or motorcycle. Car's that have been modified will have a considerable amount more though. Also, a bike that's not tuned right might puff the black residue as your shifting.

When I ran the stock muffler, I always had those black specs on the tip cover. My Two Bros exhaust doesn't have that issue.
