the fairing and tail were both on, although the tail is slightly modified. it carried myself, my wife, and about 75lbs of luggage all the way to Louisville, which is 465 miles away. on the way home, my wife rode home in comfort with my folks, while I rode the bike home with about half the luggage. I didn't see 100mpg for this trip since I changed the gearing back to 15-37 so that it would better carry the extra weight.
My trip average was 85.4mpg
the fastest it has gone to date is 85mph
the fastest I went on this trip was 75mph, and not in two up mode.

bschloop, I've also thought about making a tail section with a removable portion so that a passenger could be accommodated. Could you include a picture of how you did yours ? I haven't done it as my wife doesn't ride with me so not much motivation to do this personally but I'm sure others would like to see how you did yours.
all the best, L&S

the bike is currently apart for some maintenance, new tires, check brakes, lube everything, stuff like that. as soon as that's all finished, I will get some more detailed pics of the tail.

Based on some wind tunnel testing of some high end sport bikes the height of the tail section, and the gap between the rider and the tail section can be crucial. See the article on the "Sport Rider" website. A removable section for a passenger would be handy.

My bike might not be a sport bike, but I can very much tell that my tail section is too high. if I could squeeze one more grocery bag into the lower part of the tail, I would have it about even with my mid back so that when I lean forward the air could run off my back and onto the tail. Compromises, compromises.

Lose some FE to win (hopefully) an FE contest ... No, actually not FE contest : streamlining contest ...

How about making room for grocery bag on the sides of the engine, in front of your knees ?

that would require a wider fairing as I only have about five inches of space either side of the engine. If I did that, then I could also put one either side of the rear wheel, and make the tail shorter and wider. I don't know if this would really be an aero advantage, but it might help with side winds.

Oh, and I don't expect to win, I will be happy to be able to keep up, and post decent FE numbers. I don't have the finances to win an event like this.

To me, the only area where wider is the least penalty is the front since you are looking for a tear drop shape.

It is well explain in Craig's diary (he sets the widest part of the streamliner at his hips and shoulders.

The bike is on the trailer, and I'm packing up a few things. I made a few small tweaks to the tail, so it's back in primer gray for the time being. all things considered, I'm happy with this years project. it is not completely finished, but I'm making steps in the right direction.

Oh, and I got a new rear tire mounted. this will make three rears to one front, the front is still in great shape.
