Engine Cleaning Honda GB500

I had a bit of spare time this morning to attack the dirty cooling fins that surrounded the smog ports with their makeshift "loose change" block-offs.With some Norwex Cleaning Paste that I borrowed from the kitchen, an old toothbrush and some elbow grease, I was able to scrub most of the unsightly exhaust residue away.
