Engine Oil

Always check and change engine oil at intervals outlined in the Periodic Maintenance Chart beginning on
 page 72. Always change the oil filter whenever changing oil.

SAE15W/40 SG

 

Oil 

We strongly recommend use

 

of

 

SAE15W/40 SG

 

Oil

,

API certified 

“

S   

”

oil

. 

If

 

SAE15W/40 SG

 

Oil

 is 

unavailable,choose oil following

 

the

 

right

 

instructions

 

according  to  the  engine

 

ambient

 

temperature.

 

Oil may need to be changed more frequently if SAE15W/40 SG

 

oil is not used

. 

Follow

 

the

 

manufacture

'

s

 instructions for

ambient temperature operation.

 

CAUTION

Mixing brands or using a non-recommended oil may cause serious damage to the engine. We recommend use

 of

 

SAE15W/40 SG

 

Oil, never use substitute or mix oil brands.

Vehicle operation with insufficient, deteriorated, or contaminated engine oil will cause accelerated wear and
 may result in engine seizure, accident and injury. Always perform the maintenance procedure as  outlined in

 the Periodic Maintenance Chart.

Spark Plugs

Spark Plug Condition

Normal Plug

The normal insulator tip is gray, tan or light brown.There will be few

 

combustion deposits. The electrodes are 

not burned or eroded.This indicates

 

the proper type and heat range for the engine and the service.

NOTE: 

The tip should not be white.

 

A white insulator tip indicates overheating,

 

caused by use of an improper

 spark plug or incorrect throttle body

 

adjustments.

Wet Fouled Plug

The wet fouled insulator tip is black.

 

A damp oil film covers the firing

 

end.

 

There may be a carbon layer over

 the entire nose.Generally, the

 

electrodes are not worn.General causes of fouling are excessive oil,

 

use

 

of

 non-recommended injection oil or incorrect throttle body adjustments.

Cooling System

Operation

The engine coolant level is controlled or maintained by the recovery

 

system.

 

The recovery system compon-

ents are the overflow bottle, radiator

 

filler neck,

 

radiator pressure cap and connecting hose.

 

As coolant op-

erating temperature

 

increases, the expanding (heated)

 

excess coolant is forced out of the radiator, past the 

pressure cap, and

 

into the overflow bottle. As engine coolant temperature decreases, the

 

contracting

 

(

cooled

) 

coolant

 

is

 

drawn

 

back

 

up

 

from

 

the

 

tank

, 

past

 

the

 

pressure cap, and into the radiator.

Adding or Changing Coolant

To ensure that the coolant maintains its ability to protect the engine,

 

we

 

recommend that the system be co-

mpletely drained every two

 

years

 

and

 

a

 

fresh mixture of antifreeze and water added.

 

We

 

recommends the

 

use of

 

60/40

 

anti-freeze/coolant or a 50/50 mixture of

 

high quality aluminum compatible anti-freeze/coolant 

and distilled

 

water.

Premium 60/40 is already premixed and ready to use.

 

Do

 

not dilute with water.

NOTE: 

Always follow the manufacturer's mixing recommendations for the

 

freeze protection required in your

 area.

Any time the cooling system has been drained for maintenance or repair,

 

replace the coolant. If the recovery

 bottle has run dry, the level in the

 

radiator should be inspected. Add coolant as needed.

-90-

Cooling System

Radiator and Cooling Fan

Always check and clean the screen and radiator fins at the intervals outlined

 

in the Periodic Maintenance

 

Chart

 

beginning

 

on

 

page 72

. 

Do not

 

obstruct or deflect air flow through the radiator by installing unauth-

orized

 

accessories in front of the radiator or behind the cooling fan. Interference

 

with the radiator air flow can

 lead to overheating and consequent engine damage.

CAUTION

Washing the vehicle with a high-pressure hose could damage the radiator
fins and impair the radiator's effectiveness. Using a high-pressure system is
not recommended.

-91-

Cooling System

Coolant Level

Always check and change
the coolant at the intervals
outlined in the Periodic
Maintenance Chart beginning
on page 72

.

Maintain the coolant level between

the minimum and maximum
marks on the bottle

(

when

 

the

 

fluid

 

is

 

cool

).

1

.

 

Position the vehicle on

a level surface.
2

.

 

Remove the hood. See

 

page 36.

3

.

 

View the coolant level in the overflow bottle.

4

.

 

If the coolant level is below the safe operating range, remove the

cap and use a funnel to add coolant through the opening. Reinstall

 

the cap.

NOTE: 

If coolant must be added often, or if the overflow bottle runs completely

dry, there may be a leak in the system. Have the cooling system inspected by your dealer.

 lead to overheating and

 

consequentially, engine damage.

Escaping steam can cause severe burns.

 

Never remove the pressure cap

 

while the engine is warm or hot.

 

Always allow the engine to cool before

 

removing the pressure cap.

.

 

Remove the hood. See page 36.

Slowly remove the radiator cap.

Use a funnel and slowly add coolant as needed.

NOTE: 

This procedure is required only if the cooling system has been drained

for maintenance and/or repair. But if the overflow bottle has run dry,

 

the level in the radiator should also be 

inspected.

NOTE: 

Use of a non-standard pressure cap will not allow the recovery system

to function properly. See your dealer for the correct replacement part.

Continuously Variable Transmission (CVT) System

Belt slip is responsible for creating excessive heat that destroys belts,

 

wears clutch components and causes

 outer clutch covers to fail.

 

Switch

to low range while operating at slower speeds to extend the life of the

 

CVT components (belt, cover, etc.).

Failure to comply with the instructions in this warning can result in severe

 

injury or death.

Do not modify any component of the CVT system. Doing so may reduce its
strength so that a failure may occur at a high speed.

 

The CVT system has

 

been precision balanced. Any modification will cause the system to be out of

 

balance, 

creating vibration and additional loads on components

. 

The CVT system rotates at high speeds, creating large amounts of force on
clutch components.

 

Extensive engineering and testing has been conducted
to ensure the safety of this product.

 

However, as the owner, you have the

 

following responsibilities to make

 sure this system remains safe:

 

Always follow all recommended maintenance procedures. See your dealer

 

as outlined in the owner's manual.

This CVT system is intended for use on  CFMOTO  products only. Do not install

 

it in any other product.

Always make sure the CVT housing is securely in place during operation.

CVT System
CVT Drying

There may be some instances when water is accidently ingested into the

 

CVT system. Use the following ins-

tructions to dry it out before operating.
1

.

 

Remove the seats. See page 34.

2

.

 

Loosen the lower screws that secure the clutch cover.

3

.

 

Allow the water to drain.

4.

 

Tighten the screws.

 

5

.

 

Place the transmission in PARK. Apply the brakes.

6

.

 

Start the engine.

7

.

 

Apply varying throttle for 10-15 seconds to expel the moisture and

air-dry the belt and clutches.

 

Do not hold the throttle wide open for

 

more than 10 seconds.

 

8

.

 

Allow the engine RPM to settle to idle speed.

 

Apply the brakes.

 

Shift the transmission to the lowest avai-

lable range.
9

.

 

Test for belt slippage. If the belt slips, repeat the process.

10

.

 

Take the vehicle to your dealer for service as soon as possible.
