Mega MF 21 MasMo engine

Mega MF21 7P MasMo

Hand tuned by Massimo Fantini, the new MF.21 by Mega is designed for high end competition. Made by Novarossi and assembled by Max engines in Italy the MF.21 features, hand modified sleeve, machined piston, 14mm balanced lightweight crankshaft and other performance enhancing modifications.

Crankcase

This all new dark grey anodised crankcase has been forged from high grade aluminium and is therefore very strong and highly durable. The design incorporates many cooling fins to keep the temperature under control whilst the internal porting ensures optimised gas flow.

To ensure a perfect seal, when the carburretor is mounted, the opening for the carb has been fitted with a rubber o-ring whilst to enable the smoothest possible movement of the crankshaft the casing has been fitted with Swiss-made high quality bearings. For looks, each side of the crankcase sports the Mega Symbol and the MF.21 logo.

Cooling Head

This beautiful Orange anodised cooling head features 8 cooling fins for regulating the temperature of your engine. On top of the cooling head is the Mega Symbol, MF.21 logo and the engine categorisation symbols, all laser etched.

Combustion Chamber

Made from the finest quality alloy this combustion chamber is precision made to ensure a prefect seal even under extreme temperatures. This engine comes with a high quality 7TF glow plug.

Crankshaft

The crankshaft is a 14mm diameter, lightweight silicone filled crankshaft with hand modified, and hard-coated crankshaft bell, that reduces weight whilst at the same time significantly increasing durability. The intake through the crankshaft is optimised to allow a continuous flow of the vaporised fuel/air mixture into the crankcase. Counterweights are used to offset the weight of the connecting rod pin and crank porting. Making it more reliable, vibration-free and increasing top-end revs.

Carburettor

The MF.21 comes with a new fully adjustable 9 mm heat insulated aluminium carburettor. It has a new plastic interchangeable venturi, to control your engine’s fuel consumption. Simply change the venturi to change the consumption. The special aluminium used for this carburettor aids cooling and helps to maintain consistent settings. This carburettor has 2 needles to make adjusting simple and user friendly.

Piston & Conrod

This super lightweight dished piston has been machined from high grade aluminium and features 3 rings around its circumference for aiding lubricaton. The piston has been made using true ABC (aluminium piston, brass sleeve with chrome plating) construction for ultra long usage with little or no visible wear.

Utilising bronze bushings top and bottom the conrod is aerodynamic and lightweight therefore reducing resistance and allowing the piston to move faster.

Sleeve

This 7 port high-density hard-chromed sleeve, offers incredible durability coupled with hand modified ports ensure that maximum revs are achieved as well as producing a wide power band.

Backplate

The backplate is comes with 0-ring groove and 2 aerodynamic lugs for improved mixture flows and lubrication. The backplate also features countersunk screws to aid the insertion and removal of your engine from your car.
