Since paper filter is used in your motorcycle, it is not
advised to clean the filter. Replace the filter in case of
any abnormalities.
Caution
Do not remove the spark plug when the engine is hot.
Please ensure that the ram air duct is not getting
damaged during removal / reassembly of spark plug.
Clutch
Increase in engine speed during acceleration and
constant speed running, without increase in vehicle
speed indicates clutch slip. The clutch slip will
cause high fuel consumption, poor acceleration and
overheating of engine.
If the condition persists even after adjusting the
clutch lever play, immediately have the clutch checked
by TVS Motor Company Authorised Main Dealer /
Authorised Dealer.
Engine cum transmission oil
Dirty or less engine cum transmission oil increases
the friction between various parts of the engine
and reduces the engine life, thereby increases fuel
consumption.
Regularly inspect the engine cum transmission
oil for correct level and top-up if necessary.
Get it replaced at regular intervals as per the
maintenance schedule. Always use TVS TRU4
FULLY SYNTHETIC oil only (SAE 10W 30 API-SL,
JASO MA2).
Fuel leak
If any fuel leak from tank is suspected, tow the vehicle
to the nearest TVS Motor Company Authorised Main
Dealer / Authorised Dealer.
Tyres
Low tyre pressure has adverse effects on the vehicle.
The drag on the vehicle increases resulting in
decreased fuel economy. Further more, handling may
be affected adversely.
Caution
Never drive the vehicle with the clutch lever pressed.
This will reduce the life of clutch and affect the vehicle
performance and fuel economy.
Do not attempt to do any rectification, as fuel lines are
normally pressurized upto 3.5 bar and any activity by any
untrained personnel, may lead to un-safe condition.
