This was done a few years ago. I had a good running bike with busted up fairings and after removing them, Frankenstein was alive.
I saw this site http://scandalon.com/category/vehicles/motorcycles/ and discovered that Yamaha vstar1100 trees fit the neck and legs perfectly. This allowed another rear wheel to be mounted up front.
The old Dixie headlights and bracket were bolted through the bottom tree and plugged right into the original socket.
A cigarette lighter was mounted and used the other headlight plug. A Garmin i5 on the tank served as speedometer. The exhaust mid section was unbolted and the end slipped back on. A trailer brake light bolted on and plate zip tied. The best thing about this modification is it gives you two looks from one bike. After you have done the swap a couple of times you can easily change it back in around an hour. Take the original bike to the track during the day and come home and switch to streetfighter mode for night!
