Last tank on the truck was over 30 MPG, including towing the trike home about 46 miles.
I have the rest of the CBR parts but it's been cold so I have not done a whole lot, mostly mocking up the locations of the radiator wiring harness and the rest of the stuff it takes for a functioning vehicle.
Went to a local car show and talked with one of the exhibitors who had a 3 wheeler there. He said the seat height was no issue with the State Police inspector and he had some headlights from a bike that were small and looked great. His trike had a Hyabusa engine and the rear tire was about 12 inches in diameter. He got his trike titled as a regular motorcycle with no restrictions on where he could drive. Looks like mine will be the same.
