Jerry's Original "Howell V-Twin" (V2)

"This is a V-Twin engine that is machined entirely from bar stock. It has no prototype as it is entirely my own design. Being a single crank pin 90 degree engine, it is extremely smooth and vibration free. V type engines other than 90 degree can not be balanced except with special balancer shafts, etc. that you wouldn't want! Witness the vibrating 45 degree motorcycle engines...... The engine is a long stroke, moderate speed design which provides plenty of torque. A robust cooling system allows the engine to run indefinitly with a load and never overheat." - Jerry Howell
