s201015.jpg

High performance IFMAR legal 3 port competition engine, hand worked by Eduardo Picco, this motor is based on the high performance ZX12 DSII.

This Eduardo Modified (EM) version of the ZX12 DSII 2.1cc motor features internal work done by engine master Eduardo Picco. The crankshaft has been lightened and filled with red silicone, while the centre bore has been increased better fuel flow. The liner and combustion chamber have also been lengthened while there has also been tear dropping work done on the ports to optimise fuel flow and improve performance.

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 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, the side of the crankcase sports the new Mega Symbol on the front side and the ZX12 logo on the rear side.

Sleeve

This 3 port high-density hard-chromed liner and has been lengthened, along with the combustion chamber, while there has been tear dropping work done on the ports to optimise fuel flow and improve performance further.

Piston & Conrod

This super lightweight piston has been machined from high grade aluminium and features 2 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.

The new conrod has been made of a different material than that of previous versions and the latest design sees more material around the big end, which provides more strength for this area. Another improvement is that the piston pin is now hollow which means a considerable reduction in oscilating mass.

Crankshaft

Made from high strength steel the crankshaft is finished to the highest standard. It has been lightened and filled with red silicone, while the centre bore has been increased for better fuel flow.  The entire crankshaft has been made using a hard, wear resistant, material which increases the durability of not just this part, but the entire engine.

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.

Cooling Head

This beautiful Orange anodised cooling head features 7 cooling fins for regulating the temperature of your engine. The head has been machined around the edges to allow access to the engine mount screws as well as to make it look nicer. On top of the cooling head is the Mega Symbol, ZX12 logo, DSII logo and the new EM logo, all laser etched.

Low type head for lower center of gravity.

Combustion Chamber

Made from the finest quality alloy this combustion chamber is precision made to ensure a perfect seal even under extreme temperatures and along with the liner has also been lengthened.
