Review on 🔌 FMF Racing 11299 Black Wash Plug for 4-Stroke Engines by James Eledge

Simple product so no surprises. The plug was too big to fit into the muffler on my 2018 Honda CRF250L, so I cut off the first three or so rings with a utility knife. The core also expands like a cone, so you can still mount it on bikes with a smaller exhaust port. The "Remove Before Flight" sign is fun, although it's cheap plastic and probably won't last long.
