Secondary transmission ratio

SYMPTOMS OF IMPROPER SETTINGS

If your bike has one of the following symptoms the changes must be adjusted.
Before attempting any change make sure everything else is working properly.
Check the condition of the spark plug, make sure the ignition timing is correct,
clean the air filter, decarbonize the exhaust pipe.
If your bike has worked well up to this time it is possible that the problem is
elsewhere and therefore changing the carburetion would be a waste of time.
• Set the carburetor until the engine responds satisfactorily with the throttle
opening.
• If mixture is too lean, the engine tends to overheat. On the other hand, if
too rich, the spark plug easily gets wet causing failure. The proper mixture
varies according to atmospheric conditions (pressure and temperature).
This conditions must be taken into consideration when adjusting the car-
buretor.
NOTE: Make sure that the carburetor components that regulate the flow of fuel
and the screws that regulates the air mixture, are tight.
The secondary transmission ratio can be modified by changing the front and /
or rear sprockets.
Available GAS GAS sprockets are as follows.
Rear: 39, 40, 42, 44, 46, 47, 48, 49, 50, 51, 52, 53, 54 teeth.
Front: 12, 13, 14 teeth.
If you shorten the ratio, your GAS GAS will lose top speed but will gain in acce-
leration and low speeds, will be more manageable in difficult terrain.
NOTE: Attention to the engine rpm.
If the ratio is extended, your GAS GAS will gain top speed but lose acceleration
and maneuverability at low speeds.
