aluminum washer fitted to the
nozzle (12mm OD) shown in
figure, of the connecting tube
welded to silencer pipe
before CAT converter.
Use a Silicon Rubber tube of
approximately 300 mm to fit
onto the nozzle. Only a
Silicon rubber tube should be
used, as it has better high
temp. resistance & will not
deform / melt due to high
temp. at the nozzle.
Connect the other end of the Silicon Rubber tube to
the flexible probe pipe of machine. Ensure that the
inner diameter of Silicon tube perfectly matches with
outer diameter of flexible probe pipe of Gas Analyzer.
The Silicon rubber tube must fit snugly onto the
nozzle to prevent any air / exhaust gas leakage.
Note the CO / HC readings when the reading display
stabilizes.
As per Emission Norms the recommended CO% for 2
Wheelers is 3.5% at idling RPM. But CO% for Bajaj
Vehicles, for best results in terms of fuel efficiency
are different for different models.
If the reading is shown excess or less than BAL
specifications, try to achieve by adjusting Air Screw.
Turning in Air Screw will lead to less CO% and
turning out will lead to more CO%.
If the CO% is not falling within recommended % in
spite of adjusting the Air Screw then find out the
cause & rectify. After rectifying the problem confirm
the CO% in the same way as mentioned above.
In Discover 100 M motorcycle for better mileage and
performance achieve values given below.
The ideal CO% is
between 1.75 to 2.25% at idling RPM = 1400 + 100.
Note: Remember the Air Screw should not be taken out
more than the recommended position. Every time Air
Screw setting is changed specified Idling RPM must be
restored and then reading should be considered.
Important: For Better Mileage and Performance,
achieve CO% as recommended.
Warm up the CO Gas Analyzer
for 10~15 minutes before
proceeding further. Warming up
is essential every time machine
is put on to purge out any
gases left in side.
Carry out Span Check as per
manufacturer's
ecommendation
to confirm the OK condition of
the Equipment (If Span Check
does not confirm the reading,
R
then carry out Gas Calibration
as per mfgrs. recommendation). Set the Equipment
display to Zero before taking the reading.

Before checking CO emission, prepare the vehicle for
checking the CO.
Warm up the engine to its normal operating temp. by
riding 5~6 Kms. The c'case cover should be warm
enough by feel. (Engine Oil Temp. = 60 C).
Set CO to 1.75 ~ 2.25 %.
Set CO to 1.75 ~ 2.25 %.
Set Idling speed to specified

Caution
: In choke ‘ON’ condition CO % is high : 9~10%.
Hence warming up of engine is a must.
Note: If engine does not go off, then attend to the
additional air supply problem in the carburetor circuit &
intake system. After solving the problem once again
confirm that engine should die
down on closing the Air Screw.
