> Description

The latest motor from Mega is the DSII+ motor, the follow up to the original DSII motor, featuring some small modifications to improve performance and tuning. Made for Serpent by Picco Micromotori in Italy, this engine has a real strong pedigree.


High Res Pic - #201506 Crankcase

Crankcase

This 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 carburetor 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 ZX21 logo on the rear side.


High Res Pic - #201506 Cooling Head

Cooling Head

The cooling head has been designed to have thinner fins to reduce overall weight and to improve airflow. 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, ZX21 logo, DSII+ logo and the engine categorisation symbols, all laser etched.


High Res Pic - #201506 Combustion Chamber

Combustion Chamber

Made from the finest quality alloy the combustion chamber now features a different profile which is deeper and now features a less sloping entry to the plug which aids the ease of tuning of this motor. This part is precision made to ensure a prefect seal even under extreme temperatures. Glow plug is supplied (Mega 7 Cold #200171).


High Res Pic - #201506 Crankshaft

Crankshaft

Made from high strength steel the crank pin is incorporated into the single piece crankshaft and then further hardened using a special treatment. The fuel flow through the crankshaft has also been improved to enhance overall engine performance.


High Res Pic - #201506 Carburettor

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.


High Res Pic - #201506 Piston & Conrod

Piston & Conrod

This machined piston has been modified so that it contacts with the liner less, allowing for high revs and more speed. It also features 2 rings around its circumference for aiding lubrication and, along with the lightened piston pin, has changes that reduce the overall weight of the assembly. 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 has been strengthened with more material now surrounding both bushings for better durability.


High Res Pic - #201506 Sleeve

Sleeve

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


High Res Pic - #201506 Backplate

Backplate

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