This is terrible to hear. In addition to fire suppression systems discussion, maybe some of you 'in the know' can give the rest of us tips on how to properly plumb a fuel system to minimize the chances of this happening. I'm kind of ignorant on that subject. Perhaps a 'Safety' thread of its own is a good idea. I remember several years back when a few people in a row had head injuries that quite a few people, including myself, started wearing helmets. At least on the harder trails.
