OGY OF OGY OF
ENGINE :
The Engine helps to convert Chemical energy
availbale in petrol into heat energy then to
mechanical energy for motion. It is the heart of
the vehicle in which power is generated for
moving the vehicle.
BORE :
Bore is the inside diameter of the cyclinder block
in which Piston moves up and down.
TDC :
TDC stands for Top Dead Center. It is the top
most position to which the piston can travel in
the cylinder barrel.
BDC :

Power
BDC stands for Bottom Dead Center. It is the
bottom most position to which the piston can
travel in the cylinder barrel.
STROKE :
It is a distance travelled by piston from TDC to
BDC or Vice Versa.
CUBIC CAPACITY / DISPLACEMENT :
It is a volume generated by piston when it travels from TDC to BDC. It is measured as Cubic Centimeter
(CC). It can be mathematically arrived at with the radious of the piston and the stroke of the engine.
(πr²× l, when ‘r’ is the radius of the piston and ‘l’ is the length of the stroke). It is also known as Swept
Volume or Displacement volume.
CLEARANCE VOLUME :
It is the nominal volume of the space above the
piston in the combustion chamber when piston
is at the topmost position (TDC).
02-2
Page 10
TOTAL VOLUME :
It is the sum of the swept voume (Displacement volume) and Clearance volume.
Total Volume = Swept volume + Clerance volume.
COMPRESSION RATIO :
It is a ratio between total volume in the engine to the clearance volume available at the end of
compression stroke.
Compression ratio =
Total volume of air fuel mixture
Clearance volume
VOLUMETRIC EFFICIENCY :
Volumetric efficiency is the ratio between the volume of air fuel mixture that actually enters the cylinder
and Swept volume.
Volumetric Efficiency
= Volume of air fuel mixture inhaled during suction stroke
Swept volume
HORSE POWER (HP OR PS) :
HP : Horse Power
PS : PFERDESTARKE is German unit of power. Horse Power is the ability of the engine to do a
certain amount of work in a given time.
One Horse power is the power required for lifting a weight of 75 Kg. through vertical distance of one
meter in one second.
Conversion :
1PS = 0.986 HP = 0.735 KW
1 HP = 1.014 PS = 0.744 KW
1KW = 1.360 PS = 1.340 HP
02-3
Page 11
IHP :
IHP stands for Indicated Horse Power. Indicated
Horse Power is the power actually developed
inside the engine cylinder by combustion process.
It is utilised to drive the piston.
1HP (Horse
Power Available
after explosion)
FHP :
FHP (Frictional
Losses)
FHP stands for Frictionl Horse Power.
It is the amount of horse power used or lost to
overcome the friction between various engine
components.
BHP :
BHP stands for Brake Horse Power
BHP (Horse
Power Avaiable at
Crankshaft)
Brake Horse Power is the amount of Power actually available at the crankshaft or output shaft. It
is calculated by using dynamometer.
BHP = IHP - FHP
MECHANICAL EFFICIENCY :
Mechanical Efficiency is the ratio between Brake horsepower and Indicated horse power.
Brake horsepower = BHP
Indicated Horse power IHP
TORQUE :
Torque is a twisting or turning force or effort. It is the
product of a distance and force in circular motion.
In the picture shown the torque-applied is the product
of distance (distance between the center of the bolt
and point where force is acting) and the amount of
force applied.
With the same force, if the distance is increased,
the torque will also increase and if distance is
reduced, torque applied will also be reduced.
Ignition timing is the timing at which spark
commences so that the spark from the spark
plug can ignite the mixture in the combusion
chamber at the end of TDC during compression
stroke.
If spark occurs earlier than specified ignition
timing, it is called “Advance” timing.
If spark occurs after the specified ignition timing,
it is called “Retard” timing.
IDLING SPEED :
It is the speed of the crankshaft (i.e. RPM) of the
engine when the throttle is in closed pisition.
GEAR RATIO :
The relative rotation between “Driven Gear” and
“Driving Gear” is known as the “Gear Ratio”. It is
determined by number of teeth on the respective
gears.
TDC Position
Ignition Timing
Position
Ignition Timing in
Degrees
Gear Ratio =
No. of teeth of Driven Gear
No. of teeth of Driving Gear
In Fig. 1, the Gear ratio is 20 ÷ 10 = 2 : 1
In Fig. 2, the Gear ratio is 20 ÷ 20 = 1 : 1
Gear ratios multiply the engine torque to fulfil
various demands for pulling the vehicle like.
-More effort is required during initial
movement of the vehicle.
-More effort is required to climb an elevation.
-More effort is required while driving in
muddy or sandy surfaces.
FINAL DRIVE RATIO :
It is a relative rotation between the engine
sprocket and the sprocket on the rear wheel.
Both the sprockets are connected through drive
chain.
Final drive ratio further multiplies the torque
available at the output shaft.

If compression pressure does not
increase, then check for
- blown out cylinder head gasket
- improper torque of Rocker bearing
bolts or cylinder head nuts.
- valve seat - damage / leakage
- valvestem bend
- cylinder head warpage
Hold the throttle open fully and kick several
times (5 to 6 times).
Note down the reading and repeat the
above process 3 times. Take to average
mean reading in 100 ± 10 PSI which is the
correct compression pressure. Specified
engine compression pressure.
STEP-B
In case compression pressure is less than
80 PSI, then refit spark plug & start again
to warmup the engine.
- improper valve timing
If compression pressure reading
increases, then check for
- Improper alignment of piston ring
(end gap position)
- piston ring jamed in groove.
- scoring / seizure of cylinder barrel /
piston
- worn out piston/rings
- worn out cylinder barrel

OIL SUMP
LUBRICATION SYSTEM :
Oil from the oil tank is circulated to various parts through a powerful oil pump, the capacity of which
is 4.5 litres per minute @ 2750 rpm. The oil in the sump gets filtered through an oill strainer located
in the crankcase and then pumped into the oil filter element located in the RH Cover. From here oil
is circulated to 3 main areas. The first branch goes to flywheel to lubricate crank shaft as well as
barrel piston assembly. The second branch goes to hydraulic tappet to maintain the oil pressure
constantly. The third branch goes to rocker assembly and drains down to RH cover chamber through
the push rod tunnel.
LUBRICATION OIL :
3 Specification: MOTUL 3000 4T PLUS 15W50 API, JASO MA SL - GRADE ESTER-Semi Synthetic
3 Oil capacity: 2.75 l - Initial oil filling: through Oil filler Cap = 2.5 l, through Crankcse LH Cover: 0.25 l
Oil pump : TROCHOID TYPE
Trichoidal high flow oil pump delivers oil with a pressure of 4.5 Bar. This provides
good lubrication to all the moving parts and enhances the life of the moving
parts in the engine.

HYDRAULIC TAPPET :
The Hydraulic tappet, (also known as RHVL Roller Hydraulic Valve Lifter) is located between
the cam and pushrod in the valve train
mechanism. It not only serves as a valve lifter
most importantly, it automatically and constantly
adjusts itself to compensate for any extra
clearance in the valve train mechanism when
the engine is running at various RPM. The
automatic adjustment is achieved with the aid
of hydraulic pressure inside the hydraulic tappet.
BENEFITS OF HYDRAULIC TAPPET :
3Eliminates the need for manual and
periodic push rod height adjustments.
3Compensates for clearances in the valve
train mechanism due to wear of moving
parts OR due to variations in engine
temperature.

WORKING PRINCIPLE :
Oil enters the hydraulic tappets through a feed
hole in the body and flows into the plunger through
the plunger feed hole, filling the “low pressure
chamber” (E, in Figure)
The oil also flows around the check ball and
through the slots of the ball retainer to fill the cavity
below the plunger, called the “high pressure
chamber” (A, in Figure). Oil is forced down into
this area by momentary low pressure which
occurs once during each cam rotation.
As the hydrauilic tappet rises due to the cam
rotation, the full load of the valve train is applied
on the tappet. A predetermined and closely held
clearance of .0002/.0003 inch (.0051/.0076 mm)
between the outer diameter of the plunger and the
inner diameter of the tappet body allows a
controlled amount of oil to escape up from the high
pressure chamber.
This oil compresses the plunger spring and allows
a small relative movement of the plunger with
respect to the body.
The metering valve moves sufficiently to keep the
push rod seat hole free and unclogged. When the
engine is switched off, the valve seats on the
shoulder of the plunger to minimize drain back of
oil.
If the engine structure or valve train expands or
contracts with changes in engine temperature or
other differentials, the hydraulic tappets will
automatically adjust its own internal length to
compensate for these changes.
PRECAUTIONARY MEASURES :
The hydraulic tappets have minute holes for the
oil to circulate and to also act at the hydraulic
media, hence oil contamination must be at the
minumum. The oil and the filters in the engine,
must be changed periodically as specified.
Whenever the tappets are removed for service
OR stored in spares, they must be kept upright
(the push rod seating surface pointing upwards
and the rollers at the bottom pointing downwards)
to prevent the oil from draining off.
As cam further rotates, the tappets returns to its
original position. At this time, the plunger spring
provides the force to maintain zero back lash in
the valve train mechanism and forces the plunger
back to its original position. This allows engine oil
to once again fill the high pressure chamber so
that the cycle can be repeated during the next cam
rotation.
The overhead oil supply is accurately metered from
the “low pressure chamber”, which is at engine oil
pressure, by using a flat metal disk (metering valve
C, in Figure), which wobbles against a cylindrical
radius curved surface on the bottom of the push rod
seat (D, in Figure). Oil flows up through the hole in
the push rod seat to lubricate the overhead valve
train components (oil flow path B, in Figure).

O DECOMPRESSORO DECOMPRESSOR
O DECOMPRESSOR
O DECOMPRESSORO DECOMPRESSOR
WORKING PRINCIPLE
The auto decompressor is assembled in the
exhaust cam and consists of a flyweight, spring
and pin. These are assembled in the cam
assembly with a screw
During inital cranking of the engine, the cam
rotation will be under 350 RPM. At this speed,
the flyweight will be at its resting position which
causes the pin to protrude above the base circle
of the cam lobe. This will cause the hydraulic
tappet to raise and will cause the exhaust valve
to be open thus letting out the compression form
the cylinder head.
As the engine starts, the cam rotation increases
beyond 350 RPM which inturn will cause the
flyweight to open and force the pin to rotate and
its projection will go below the cam lobe. This
will cause the tappet to return to its resting
poisition and will close the exhaust valve thus
holding the compression required to start the
engine
BENEFITS OF AUTO DECOMPRESSOR :
3Eliminates the need to fix a manual system
which will need to be adjusted and serivced
periodically.
3Helps in easy starting of the engine
3Helps to reduce high initial load on the
electric start motor

The auto chain tensioner has a spring loaded plunger mechanism with a ratchet arrangement. It
eliminates need for manual adjustment of the primary chain tension.
It is assembled on the crankcase LH below the chain tensioner pad. The spring loaded plunger
applies force on the chain tensioner pad thereby lifting it and holding aginst the primary chain to the
required tension.
The oneway rachet mechanism in the auto chain tensioner ensures that the plunger does not drop
down due to the downward force of the chain tensioner pad.
It does not require any maintenance or service.

The engine breather system is located on the RH cover of the crankcase. A connecting hole directs
the engine breathing into a chamber in the RH cover which has an inbuilt deflector to deflect the oil
that may come along with the fumes from the crankcase. This oil gets drained through a small hole
provided at the bottom of the breather chamber.
The emission passes through the deflector chamber and goes to the air filter housing and passes
through the inlet manifold back into the cylinder head.

The inlet manifold has the fuel injector located on top portion and the throttle body attach to it.
The throttle body has a butterfly valve attached which is operated buy the throttle cables attached to
a drum on the right side.
A manual Bi starter is located on the left side and is the spring and plunger type arrangement.
An idle air bypass screw is provided on the throttle body. It is the large brass coloured screw that is
accessed from the top of the throttle body. The clamps on the throttle body may be loosened and the
throttle body rotated outwards from the top to access the screw without removing the fuel tank and
to adjust the idle speed with the bike running. Turn the screw CLOCKWISE (in) to DECREASE the
idle speed. Turn the screw ANTICLOCKWISE (out) to increase the idle speed. Remember that this
is an AIR BYPASS screw – not a throttle stop screw. Turning the screw about ¼ turn will result in an
approximate 200 RPM change in the idle speed. DO NOT adjust the throttle stop screw on the side
of the throttle body unless you are using the factory software to recalibrate the base throttle opening.
