Introduction

Introducing the MF21 'Nine', the latest Novarossi based motor in the Mega engine line from tuning master Massimo Fantini. Featuring 9 ports, ceramic bearings and lightened crankshaft, this 3.5cc motor is for serious racers only.

Crankcase

This black 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 hand tuned internal porting ensures optimised gas flow.

The crankcase also features a full ceramic main bearing in the motor for better durability and smoother rotation of the crankshaft. The outside of the crankcase sports the Mega Symbol on the front side and the MF21 logo on the rear side.

Cooling Head

The orange anodised cooling head has been newly designed with the machined cooling fins receiving a new look. The fins have also been given more surface area to allow the heat build up to be dissipated more effectively. The top of the cooling head sports the Mega Symbol, MF21 logo and the engine categorisation symbols, all laser etched.

Combustion Chamber

Made from the finest quality alloy, the combustion chamber is precision made to ensure a prefect seal even under extreme temperatures. Glow plug is supplied (Mega 7 Cold).

Crankshaft

The crankshaft on the new 'Nine' is not only a hand tuned high performance part but also a work of art. Lightened, the crankshaft sports red silicone for smooth fuel flow while the bell crank has been hardened, balanced and now sports a large turbo scoop to ensure even better fuel flow up to the combustion chamber.

Sleeve

This 9 port high-density hard-chromed sleeve, has been hand ported by Massimo himself and is now optimised to provide maximum revs and a wide power band.

Piston & Conrod

This piston has been made using micro casting which gives it a denser surface so it has a smoother movement and is more durable. It also features 4 oil rings around its circumference for aiding lubrication and the top of the piston has been dished for even combustion

Utilising bronze bushings top and bottom the conrod is a Novarossi R7 type which has been optimised to be more aerodynamic as well as very durable.

Carburettor

This easy to adjust 2 needle carburettor maintains its needle settings, regardless of temperature, thanks to its design and the materials used in its construction. This carburettor comes with 3 different venturies that can be easily interchanged to fine tune your fuel economy.

Backplate

The crankcase backplate is cast and features a 0-ring groove and 2 aerodynamic lugs for improved mixture flows and lubrication.

Packaging

Comes in a Mega box along with instruction manual and decal sheets.
