The oil breather on the Triumph Triples goes into the airbox, and if the bike is dropped on its left side whilst running, it will suck oil into the engine, creating a Hydrolock situation. A lot of people have circumvented this by running the breather hose into a small plastic bottle with holes punched into it, and stuffed up next to the battery box. I've only dropped mine on the right side, so haven't done that mod yet.
