Thanks for the comments guys.
Geo, the tube comes off easily, but it is sealed up front with closed cell foam. It won't keep everything out, but it won't get in easily either. I will take some more detailed pics before I go to Maxton in April.
Kent, thanks, I'm gonna run it at Maxton like you see it, but I will have the full fairing you made on it by the time it hits the salt. Doesn't really matter though, since it will come apart for cleaning and maintenance after speed week.
