GENERALDESCRIPTIONOFTHEENGINE
This engine of the "TaG" series (Touch and Go) has been expressly designed and
developed for the powering of karts for hobby racing on closed tracks, destined for this
specificpurpose.Whendesigningthisnewlineofengines,thetechnicalsolutionsalready
adopted for thehigh performance engines were used,in order to guarantee the highest
reliabilityofcomponents,whentheoperatinglimitationsarerespected.
Themotorisasinglecylinderusingthetwostrokeprinciple.
Thecylinderandthecrankcaseareinaluminiumalloy.
The pressed in liner is made of centrifugated cast iron, fully machined to guarantee the
bestpossiblestability.
Theheadisseparatedfromthecylinderandsecuredbystuds.
Thecrankshaftisbuiltandsupportedbytwoballbearings.Thecrankshaftisofsteelalloy,
hardenedandtempered,asistheconnectingrodwhichrunsonrollerbearings.
The digital ignition with capacitive discharge is fed by a magneto which generates the
spark energy for the starting of the engine, supplies the advance timing through an
integratedpickupandrechargesthebattery.
The ignition includes a digital electronic unit (powerpack), the statorrotor, the starter
relay,theH.T.coil,aswitchkeyassembly,andthewiringharness(witha5Afuse)which
connectsthewholesystem.
Theelectronicboxwhichcontrolstheadvance,therev.limitationandtheenginestart/stop
logic,integratesthevoltageregulatorandtheignitioncircuit.
Thestarterrelay(SolidtypeSSR),protectedfromshortcircuits,suppliesthepowerforthe
electricstarterandiscontrolledbythepowerpack.
AnRPMlimiter,integratedinthepowerpack,preventstheenginefromexceeding17000
RPMduringuse.
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.
With the starter key in “RUN” position, the starter activates a Bendix type gear which
engagesthestarterringassembledontheclutch.
Theengineisprovidedwithanautomaticdrycentrifugalclutchwithlowmaintenanceand
withinterchangeablesprocket.
The carburetor is a diaphragm Tillotson carburetor with integral fuel pump, filter and all
positionmountingcapability.
The battery (12 V  9Ah) is a sealed, no maintenance battery and is supplied already
preassembled, in the battery support box which can be easily adapted to all existing
chassis.
Theexhaust,includedinthesupply,isalreadytunedforthebestpossibleperformance.
Theengineissuppliedwithakitwhichincludestheradiator,thepump,waterhosesand
whatevernecessaryfortheassemblyonthekart.
