The motor is of the high efficiency, long-stroke type, with 2 11-16 inch bore and 31-2 inch stroke, giving 79.4 cubic inches displacement. Extreme care has been given every detail of design to produce the highest degree of efficiency, pep and pulling power. The intake manifold has been materially enlarged with sweeping intake passages to facilitate filling the cylinders, and to distribute charges equally to all the cylinders, which is an important factor in flexibility and smooth running at all speeds. The cylinder design of the special "De Luxe" model has also been changed. Larger intake passages into the cylinders have been provided, with the least possible restriction to impede the passage of gas charges. The exhaust passages have been correspondingly enlarged and improved. | The motor is of the high efficiency, long-stroke type, with 2 11-16 inch bore and 31-2 inch stroke, giving 79.4 cubic inches displacement.

The Henderson force feed oiling system has been so highly developed that the only attention required on the part of the rider is to maintain a proper supply of oil in the crank- case sump. The oil is circulated by a positive gear pump through pipes and ducts into all the crankshaft main bearings and through the hollow crankshaft into all the connecting rod bearings, maintaining motor efficiency in extra hard service and altogether preventing wear. Detail refinements in the oiling system of this "De Luxe" model, to provide for the increased speed, also insure perfect distribution of oil to all bearings and cylinders, and have reduced oil consumption fully 106%. | The Henderson force feed oiling system has been so highly developed that the only attention required on the part of the rider is to maintain a proper supply of oil in the crank- case sump.

All interior motor parts are oversize and have a great factor of safety. There has been an erroneous impression that four-cylinder machines are necessarily more delicate than twins. | All interior motor parts are oversize and have a great factor of safety.

The crankshaft bearings are 1 1-4 inch in diameter; the connecting rod bearings are 1 1-4 inch in diameter and 11-8 inch long; the wrist pins are 5-8 inch in diameter, and the wrist pin bearing surface in the pistons on either side of the conneti ing rods is 1 3-8 inches. | The crankshaft bearings are 1 1-4 inch in diameter; the [[connecting rod]] bearings are 1 1-4 inch in diameter and 11-8 inch long; the wrist pins are 5-8 inch in diameter, and the wrist pin bearing surface in the pistons on either side of the conneti ing rods is 1 3-8 inches. | ||
The Henderson side-by-side valve arrangement is retained in the "De Luxe" model because of its compactness, accessibility and general suitability. | The Henderson side-by-side valve arrangement is retained in the "De Luxe" model because of its compactness, accessibility and general suitability. | ||
