Very nice American Henderson model K- De Luxe from 1924. This is a 4 cylinder side valve of 1300cc. Unfinished project of a Board track racer. Motorcycle is not finished yet. To build this racer there is nothing broken or sawn off. The mudguards and the standard handlebars are there as well. The engine comes with NOS connecting rods and valves with springs. Nice project to finish.
