One thought on “This monster was fitted with a car tire on the rear and a m/c tire on the front. Glenn built the engine for an experimental aircraft owned by Dr.Silverton of Milwaukee. Glenn wished to test the engine before delivery so he built this motorcycle around it.. And road it to 137 mph @ Ormond Beach, Florida. The engine developed 40 hp and used two carburetors. Bore and stroke were 3 1/4″ x 3 1/4″.”
