Originally invented by SISF, you do the deed (easily) w/ a 24" long rebar and a BFH. Have a friend hold the bike firmly w/ front brake. SAY: "THIS MIGHT SMART A LITTLE BIT", Then tap the pointed end of the rebar through the baffle. Repeat on the other side...no muss, no fuss, no crumbs to clean up.
I fixed it for you!
