Starting A Warm Engine - Yamaha YFM90RA Owner's Manual

6. If the engine is started with the choke in posi-
tion (1), the choke should be returned to posi-
tion (2) to warm up the engine. If the engine is
started with the choke in position (2), keep the
choke in this position to warm up the engine.
NOTICE
For maximum engine life, always warm the en-
gine up before starting off. Never accelerate
hard when the engine is cold!

7. Continue warming up the engine until it idles
smoothly, then return the choke to position (3)
before riding.
TIP
The engine is warm when it responds normally to
the throttle with the choke turned off.

Starting a warm engine

Follow the same procedure as for starting a cold
engine, with the exception that the choke is not re-
quired when the engine is warm. Instead, start the
engine with the throttle slightly open.
To start out and accelerate
1. Squeeze the front brake lever to release the
parking brake.
2. Gradually open the throttle while slowly re-
leasing the rear brake lever.
WARNING
Opening the throttle abruptly could make the
ATV wheelie, which would increase the chance
of an accident, including an overturn.
To decelerate
When slowing down or stopping, release the throt-
tle and apply the brakes smoothly and evenly. Im-
proper use of the brakes can cause the tires to lose
traction, reducing control and increasing the possi-
bility of an accident.
