Section 1 - DESCRIPTION OF THE "Parilla REEDSTER 125cc"ENGINE

1.1 MAIN FEATURES

The "Parilla Reedster" engine is the result of the decennial racing experience of IAME and
it contains many technological and construction innovations which enable the engine to
achieve both high performance and guarantee excellent reliability and endurance
characteristics.
This engine has been designed and tuned for powering the karts for both hobby and
agonistic racing on closed tracks destined for this specific purposes.
When designing the engine we have considered the technical solutions already adopted
for the high performance engines and the experience acquired with the "TaG" series
engines (Touch and Go).
The "Reedster" engine has been homologated in 2006 according to the CIK/FIA
international rules and it is available in 4 versions: F1, F2, F3 ed F4.
This engine is a 2 stroke single cylinder.
The thermic group and crankcase are in aluminium alloy.
The pressed-in liner is made of centrifuged cast iron and machined from the full to
guarantee the best possible stability sliding homogeneity and precision.
The head is secured by 5 screws to the cylinder which is fitted to the crankcase by 4
studbolts.
The crankshaft is of the built up type and supported by two ball bearings. It is of steel alloy
hardened and tempered, as is the connecting rod which is machined from the full. The rod
runs on roller bearings on both ends.
The crankcase houses a balance shaft, driven by two gears, which rotates opposite to the
crankshaft thus reducing the engine vibrations.
The digital ignition with capacitive discharge, is fed by a magneto which generates the
spark energy for the starting of the engine, guarantees the advance timing through an
integrated pick-up and recharges the battery.
The ignition includes a digital electronic unit, the stator-rotor, the starter relay, the H.T. coil,
a switch key assembly, and of course the wiring harness (with a 5A fuse) which connects
the whole system.
The electronic box, which controls the advance, the rev. limitation imposed by the CIK/FIA
rules and the engine start/stop logic also integrates the voltage regulator and the ignition
control circuit.
The starter relay (Solid type SSR), protected from short-circuits and overloads, supplies
the power for the electric starter and is controlled by the electronic unit.
The spark is generated also without a battery; it is therefore possible, in case of
emergency to start the engine with an external starter unit.
When the starter key is in the "RUN" position, the electric starter activates a Bendix type
gear which engages the starter ring assembled on the clutch.
The engine is provided with a dry centrifugal clutch with low maintenance and with
interchangeable sprocket.
