This Picco Micromotori made engine has been
further developed to improve durability. The performance, combined
with low fuel-consumption was already very good, but has improved
The combination of a lighter piston and lighter
piston pin and redesigned conrod creates a more durable and higher
reving engine. The cylinder head has been sligtly modified to
reduce vibrations. The superbly machined one pieces balanced
crankshaft has a nice black finish.
The EFRA 2033 pipe with conical header ( # 203045)
is the best working option for 3-chamber pipes and the 9897 pipe
for the 2-chamber pipes (#203013 = outlaw).
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 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 ZX21 logo on the rear side.
The cooling head has been redesigned 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.
Made from the finest quality alloy this combustion
chamber is precision made to ensure a prefect seal even under
extreme temperatures. Glow plug is not supplied (recommend Mega
7 Cold #200171).
Made from high strength steel the crankpin has
now been 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
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.
Piston & Conrod
This machined piston features 2 rings around
its circumference for aiding lubricaton and, along with the piston
pin that has also been lightened, features 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.
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.
The crankcase backplate is cast and features
a 0-ring groove and 2 aerodynamic lugs for improved mixture flows
