CFMoto motorcycle CF650NK. Service Manual - part 8

Painted Surfaces

After washing your motorcycle

，

coat the painted surfaces, both metal and plastic, with a commer-

cially available motorcycle/automobile wax. Wax should be applied once every three months or as

 conditions require. Always use non-abrasive products and apply them according to the instructions

 on the container.

Windshield And Other Plastic Parts

After washing, use a soft cloth to gently dry off plastic parts. When dry, treat the windshield, headlight

 lens, and other unpainted plastic parts with an

 

approved

 

plastic

 

cleaner

/

polisher

 

product

.

CAUTION

Plastic parts may deteriorate and break if they come in contact with chemical substances

 or household cleaning products such as gasoline, brake fluid, window cleaners, thread-

locking agents, or other harsh chemicals. If a plastic part comes in contact with any harsh

 chemical substance, wash it off with water and a mild neutral detergent immediately, and
 then inspect for damage. Avoid using abrasive pads or brushes to clean plastic parts, as 

they will damage the plastic parts' finish. 

Chrome and Aluminum

Chrome plating and uncoated aluminum parts exposed to road salt or salt in the air in coastal areas

 are susceptible to corrosion if not properly cleaned. Coated aluminum should be cleaned with a mild

 neutral detergent and finished with a spay polish. Both painted and unpainted aluminum wheels can

 be cleaned with non-acid based wheel spray cleaners.

Leather, Vinyl, and Rubber

If your

 

motorcycle

 

has

 

leather

 

accessories

,

special

 

care

 

must

 

be

 

taken

.

Use

 

a

 

leather cleaner/

treatment to clean and care leather accessories. Washing leather parts with detergent and water will

 damage them, shortening their life.

Vinyl parts should be cleaned with the rest of your motorcycle, then treated with a vinyl treatment.

The sidewalls of tires and other

 

rubber

 

components

 

should

 

be

 

treated

 

with

 

a

 

rubber

 

protectant

 

to preserve their life

. 

WARNING

Special care must be taken not to get any rubber protectant on the tire tread surface when

 treating. This may decrease the traction between tire and ground, causing the vehicle loss 

of control.

-108-

STORAGE

Preparation for Storage

Clean the entire vehicle thoroughly.

Run the engine for about 5 minutes to warm the oil, shut it off, then drain the engine oil.

WARNING

Motorcycle oil is a toxic substance. Dispose the used oil properly. Contact your local 
authorities for approved disposal methods or possible recycling. Plus, keep the used

 oil out of reach of children.

Fill in fresh engine oil.

Empty the fuel tank with a fuel pump or siphon.

WARNING

Gasoline is extremely flammable and explosive under certain conditions. Turn the ignition

 key to “OFF”. Don't smoke. Make sure the area is well ventilated and free of any source 

of flame or sparks; this includes any appliance with a pilot light. Gasoline is a toxic substance.

 Dispose of gasoline properly. Contact your local authorities for approved disposal methods.

Empty the fuel system by running the engine at idle speed until the engine stalls.

（

if left in for a

 long time, the fuel will break down and clog the fuel system.

）

Reduce tire pressure by 20%.

-109-

Set the motorcycle on a box or stand so that both wheels are raised off the ground. (If this can

'

t be

 done, put boards under the front and rear wheels to keep dampness away from the tire rubber.

)

Spray oil on all unpainted metal surfaces to prevent rusting. Avoid getting oil on rubber parts or in 

the brakes.

     Lubricate the drive train and all cables.

Ensure that the battery is fully charged before storage. Remove the battery and store it out of the 
sun and in a cool, dry place. 

  Tie plastic bags over the muffler to prevent moisture from entering. 

Put a cover over the motorcycle to keep dust and dirt from collecting on it. 

Preparation after Storage

Remove the plastic bags from the muffler.

Install the battery in the motorcycle and charge it if necessary.

Fuel the fuel tank.
Check all the points listed in Daily Safety Checks section.

Lubricate the pivots, bolts and nuts.

WARNING LABELS ON MOTORCYCLE

Please read all warning labels on the

 

motorcycle and heed their instructions before your first riding

If any of the labels depicted in this manual differ from the labels on your ATV

,

always read and follow

 

the instructions of the labels on the

 

ATV

.

EFI ERRORS CODING TABLE

Short Flashing [S.F.] =Units Digit of Error Number

Long Flashing [L.F.] = Tens Digit of Error Number

S.C. = Short Circuit to battery

S.C.G = Short Circuit to Ground
O.C. = Open Circuit

The error indicator light is at right and lower corner of dashboard. If the indicator

 

flashes

,

then it 

means

 

EFI

 

system has something wrong

.

Below table shows what kind of error every flashing

 condition stands for

.

There are two different kind of

 

flashing. Long flashing means tens digit and

 short flashing means units digit. Long flashing occurs firstly and then short flashing occurs. One 

Long Flashing means ten, two Long

 

flashing means twenty and so on. For instance, as for error 

code 

“

23

”, 

after error indicator lighted and will have

 2 

times of long flashing and then

 3 

times

 

of short flashing.

1-2 GENERAL INFORMATION 

Safety Precautions

Exhaust contains toxic ingredients. Do not run the 

engine in enclosed or poorly-ventilated areas.

The liquor (dilute sulfuric acid) in Battery is strongly 

corrosive; it may burn the skin and blind the eyes 

when it contacts them. In case of contact, please  

wash it with a great deal of clear water immediately, 

and seek medical treatment in hospital. Besides,  

please also wash it by a great deal of clear water 

when it contacts the clothes, for avoiding skin burn. 

The Battery and Battery liquor must be stored  

strictly out of reach of children.

Uniform (pilot uniform etc), cap, safety boots  

suitable for the operation must be worn, and the  

safety articles such as dustproof goggles, dustproof 

respirator and gloves shall be worn for protection  

when necessary.

When the engine just stops, the temperature  

of engine, muf fler is still high; please do not  

touch them with bare hands, for avoiding burn. 

Please wear uniform with long sleeves as well  

as gloves when maintaining.

The coolant is poisonous, please do not drink it,  

do not let it contact the skin, eyes neither clothes. 

In case it contacts the skin or clothes, please  

rinse it immediately . When it contacts the eyes,  

please wash it thoroughly with a great deal of clear 

water immediately, and seek medical treatment in  

hospital. In case the coolant is drunk by mistake,  

please try to throw it up, and seek medical  

treatment immediately after gargling.  The coolant 

must be stored strictly out of reach of children.

No smoking or naked fire is allowed at the  

operation site, for the gasoline is combustible. Not 

only f ames, but electric sparks shall be avoided.  

Besides, the vapored gasoline is explosive, please 

operate it in the place with nice ventilation.

GENERAL INFORMATION 1-3

Safety Precautions

The Battery may produce combustible and  

explosive hydrogen when it is being charged. So it 

may explode if there is  f ame or electric spark. So 

please charge it in the place with nice ventilation.

Do not touch the turning or movable pieces such 

as rear wheel, clutch, etc. Pay attention not to get 

pinched when servicing.

The personnel shall make them be aware of each 

other from time to time when operating, for safety 

conf rmation.
