Well, I take a different tack. I have 4 friends that keep a total of 6 of my bikes at their places. 5 trikes and a quad. They keep them in good shape and fix what they break. If they do not fix them they can't ride. I was blessed with a pile of trikes, so I let other people use them. It helps me keep the pile of them running. At a ride I jump on what I want and they ride the rest.
Trikes: Cagiva 200, 85? Tiger 250,(2)84 200x's , (3)86 200x's, 87 200x, (5)85 350x's, (2)86 350x's, (2)85 250r's, 86 Tecate, (3) 85 250sx's Restoring: 83 200x, 86 250sx. Too many utility trikes to list.
