Novarossi Mephisto .21 Off Road 3.5cc Buggy Engine (Rear Ceramic)

Description

Rear cover: The rear cover presents a round shape to optimize the filling and reducing the dead spaces. the steel plate is to reduce friction and to expand the lifespan of the conrod. Sleeve: The sleeve has 4 transfer ports to supply a linear power output and to keep fuel consumption low. Crankshaft: The crankshaft is manufactured with a larger bore intake to increase the mixture flow and has a special shape to optimise gas-flows in the engine. The durability has been significantly improved with the DLC coating. Combustion chamber: The combustion chamber is supported by an O-Ring which is placed between the combustion chamber and the crankcase to reduce the vibrations of the combustion chamber. Conrod: New R4/18 conrod, redesigned and made with a special aluminum alloy that allows it to have a high resistance while maintaining the lightness and performance of the previous R4/17. Carburettor: The three tuning needles gives a better idle and improves the ability of the engine to return to low rpm after throttling. Cooling head: New head, redesigned to improve the flow of air and thus increase cooling and ensuring an optimal center of gravity. Rear ball bearing: The rear ball bearing has high quality ceramic balls to minimize wear and inertia to improve acceleration and fuel consumption.
