Build Your Own Haynes V-Twin Motorcycle Engine
From the makers of Haynes mechanics manuals and the original Haynes V8 Model Engine this model offers a realistic engine building experience with 150 parts that run animated once assembled using 3AA batteries (not included).
Build a fully functional, motorized model of a V-Twin motorcycle engine. Engine is designed in a 90 degree "V" configuration, with simulated chain driven overhead camshafts, working valves and illuminating spark plugs. It features plated exhausts, engine covers and air filter cover, and plays an engine sound while the model operates.
Contains nearly 100 pieces and all that you need to assemble the model. Comes with a Haynes style manual giving you step by step instruction as well as interesting information about V-Twin engines.
Short of getting a motor out of an old car, finding a set of mechanics tools, and donating a few days of clothes to the grease monster, the Haynes engine kits are still the best way to get hands on experience with how an engine works. Having personally rebuilt several engines, I have to say that the accuracy and detail is astounding, giving the builder the opportunity to discover what all the moving parts do in an engine. These models bridge the gap between mechanics books that talk about race cars and engines and actually working on one yourself. You'll develop a deeper appreciation all of an engine's components that work together to produce rotating force.
Additionally from the supplier: “The V-Twin engine model is designed to simulate the process of an internal combustion engine. It is not engineered to propel or function in any manner other than the demonstration (with sound, lights and electrically generated motion) the functionality of a real engine. There is no drive system.”
