Cozmo, with the db-killer it just sounds deeper, without the db-killer it just sounds very hard and deeper, so db-killer installed again. I ride in Germany a lot and I don`t want any hassles.
Feet up: my riding gear was relatively clean, just the lower end above the feet was a bit dirty, but just brushing that of when it`s dry did the trick. Process for cleaning:
removing all lower side panels, a thorough wash with just water, then applying Motowash on it, let it soak in for about 20 minutes, then using al kinds of brushes and sponges to wash it, repeating that until it`s clean.
