3.1.2 FUEL, OIL AND ENGINE

COOLANT RECOMMENDATION

FUEL: Use unleaded gasoline that is

Graded 92 octane or higher.

ENGINE OIL: Use 4-stroke motor oil,

the oil need to meet API service
Classification SG or higher. If engine
oil with a SAE 15W-40 is not
available, choose from the right chart
according to the environmental
temperature.

ENGINE COOLANT: Since antifreeze also has corrosion and rust-

inhibiting properties, engine coolant contains antifreeze, and the freezing
point should below the atmospheric temperature like 5℃.

Recommended coolant type: -35℃ anti-frozen, antisepsis, high-boil

coolant.
Danger: Keep the engine coolant properly and do not drink it
as it is poisonous

Warning: Do not mix other brand engine coolant together.

3.1.3 Engine running-in

As the engine has a lot of relative motions parts, such as pistons, piston
rings, cylinder blocks and inter-meshing gears, thus, good operation at the
beginning is necessary. It helps a good adaptation to each part, adjust
working gap, and make a smooth friction surface to bear heavy load.

Recommended running-in time: 20 hours, see detailed specification

below:

0～10 hours

Avoid continuous operation above half-throttle or vary the speed of the

vehicle from time to time. Do not operate it at one set throttle position.
Allow a cooling-off period of 5 to 10 minutes after every hour of operation.
CHAPTER 3 ENGINE PAGE. 3- 4

CHAPTER 3 ENGINE M565Li T3 EFI SERVICE MANUAL 20.0

Avoid acceleration heavily. T he accelerator should be changed smoothly,

avoid changing heavily from small to bigger

10～20 hours

Avoid prolonged operation above three-quarter throttle. Allow using freely

but not full throttle.
CAUTION： Maintain and repair as regular procedures during
break-in period;

After break-in, do not forget to check and maintain the engine

before normal use

3.5.2 INJECTOR

3.5.2.1 Appearance

The figure below shows the standard Multec 3 Fuel Injector appearance

3.5.2.2 Seal rings

Seal rings for injectors (refer to Figure 12) are made to withstand temperatures

ranging from -40℃to 150℃(-40 to 302℉) without leakage or seeping. They must also be
resistant to varying amounts of fuel additives to fuel (i.e., ethanol, etc.). The following are
currently available seal rings designs. Please contact a Delphi representative if the
specific sealing requirements are not met by these designs:

Injector to fuel rail seal ring

Injector to manifold

• Dimensions:

• ID: 9.61 mm

• OD: 14.49 mm

• Cross-section: 2.44 mm

• Materials:

• Viton A (black or brown other applications.)

3.5.2.3 Seal rings replacement

Lubricate the seal rings with an approved lubricant or equivalent. The lubricant
application process must prevent lubricant from contacting the director plate, which could
possibly restrict the injector flow.

It is preferred to not reuse the seal rings when re-installing an injector. If re-use is
necessary, carefully inspect each seal ring for any signs of damage, as even minor
defects can lead to fuel / vacuum leakage. Always install injectors and seal rings using
the recommended service procedures to avoid the possibility of a safety hazard.

When installing seal rings to the injector inlet, take extra care not to damage the seal
on the injector top flange.

3.5.2.4 Lubricant Recommendation

Lubrication should be applied to the O-rings only for ease of injector installation.

The table 4 is a list of lubricant oils that were tested and approved for O-ring lubrication.
These lubricants have shown to have no effect on injector performance (plugging,
sticking).

CHAPTER 3 ENGINE PAGE. 3- 105

CHAPTER 3 ENGINE M565Li T3 EFI SERVICE MANUAL 20.0

3.5.2.5 Over-Voltage

The Multec 3 injectors and the Multec 3.5 injectors can withstand a voltage of 26v for a
maximum of one minute at a duty cycle of 100 ms pulse width and 200 ms period. The
injector will be pressurized with calibration test fluid at normal operating pressure during
the test. This will not result in any permanent physical damage to the injector or coil
assembly, or any degradation in electrical performance.

3.5.2.6 Temperature Requirements:

Typical injector temperature environments are defined below. The Multec 3 injectors and
the Multec 3.5 injectors will not experience any loss of the ability to comply with the flow
tolerance requirements after exposure to the following temperature environments. Also,
they will not experience unacceptable external leakage, any type of physical degradation,
or loss of service life during or after being exposed to these ambient conditions.

Normal Operating Temperature Range: - 30 to 125C

Extreme Operating Temperature Range (some performance degradation): - 40 to

150C

Storage Temperature Range: -60 to 60C

3.5.2.7 Fuel Contamination

The injector fuel inlet filter protects the fuel injector from initial build fuel contamination as
well as from fuel system assembly contamination. Filtration is extremely important
because particle contaminants can cause an injector to stick open, flow shift or tip leak.

The injector inlet filter is not a serviceable component and is designed only to trap
potential built-in contamination between the chassis fuel filter and injector.

3.5.2.8 Wire Routing

CHAPTER 3 ENGINE PAGE. 3- 106

CHAPTER 3 ENGINE M565Li T3 EFI SERVICE MANUAL 20.0

Electrical wiring to the injector should be routed so that conductors are protected from
excessive heat, damage, and wear.

Avoid unnecessary handling (disconnecting and connecting) of the electrical

connector.

material with a tag that describes the problem.

3.5.2.10 Installation guide lines

Follow these guidelines to prevent damage to the injector and it’s electrical interface
during the replacement or re-installation process.

Lubrication: Apply a light coating of lubricant to the lower injector seal ring. ISO

10 light mineral oil or equivalent is recommended.

The preferred technique is to apply the lubricant to the sockets the injectors are being
installed into, rather than directly to the seal ring itself. This will help minimize the
possibility of injector contamination.

Avoid applying lubricant over the director plate holes – this may restrict injector flow.
Do not dip the injector tip in lubricant.

All Multec 3 and Multec 3.5 injectors come from the factory with the seal rings

attached. The re-use of seal rings is not preferred when replacing an injector. If an
injector is to be re-used, and no new seal rings are available, take care to inspect each
seal ring for signs of damage. Even minor defects in the seal ring can lead to leakage.
Take extra care in installing seal ring over flange of injector inlet.

Carefully installing the harness connector will prevent terminal damage. Listen for a
CHAPTER 3 ENGINE PAGE. 3- 108
CHAPTER 3 ENGINE M565Li T3 EFI SERVICE MANUAL 20.0

positive audible click from the connector retention device — this ensures that it is fully
engaged.

Avoid unnecessarily disconnecting/reconnecting the harness connector.

Wires routed in a manner that can allow them to become pinched between
components can result in a short circuit and a stuck open injector.

For injectors that require orientation for spray pattern, do not rotate the injector in the
fuel rail assembly to install the injector electrical connector. This may dislodge the
retaining clip, and result in improper spray orientation

3.5.2.11 Replacement Techniques

The following procedure outlines standard Multec 3 and Multec 3.5 Fuel Injectors
removal and replacement.

Warning: The injector and all associated hardware may be extremely hot.

Shut off ignition.

Disconnect negative battery cable to avoid possible fuel discharge if an accidental

attempt is made to start the engine.

Disconnect the electrical connector from the injector wiring harness.

Relieve fuel pressure

Remove the retaining clip from the fuel injector.

Remove the fuel line connection from the injector

Carefully clean debris from the interface surfaces. Do not damage seal mating

surfaces.

Remove the injector from the manifold

Apply a light coating of a lubricant to both the upper and lower injector seal ring of the
replacement injector.

Install the new injector into the manifold. Check that the injector is installed in the
original orientation to maintain proper spray targeting, and that the retaining clip is
properly seated on the injector and the fuel line

Install the retaining clip after connecting the fuel line

Tighten the injector mounting to the desired torque as mentioned in the manufacturer
manual

Tighten the fuel line

Re-install the injector electrical connector

CHAPTER 3 ENGINE PAGE. 3- 109
CHAPTER 3 ENGINE M565Li T3 EFI SERVICE MANUAL 20.0

Check for fuel leaks with the key “on” and the engine “off”

Start engine and verify proper operation

3.5.2.12 Interchange ability

The injector should be replaced in service only with an equivalent injector of the same
part number. On occasion, a new part number may supersede part numbers. Consult the
appropriate vehicle service manual and part number guide for the latest replacement
injector part number information.

5.5.2.13 Plugging

Fuel deposits cause plugging resulting in flow shifts over the life of the injector.

Fuel varnish or gumming, a type of injector deposit, is created when certain types of fuel
are heated by high injector tip temperatures at soak (no fuel flow). Deposit build up in the
director holes causes the flow shifts

Plugging can cause flow restrictions, frictional changes and the collection of other
particles attracted by the tacky surface. The flow restrictions can degrade emissions and
drivability.

Other fuel and environmental conditions may cause crystal or corrosion growth in the
injector and cause a flow shift.

Oxidation stability of the gasoline affects the potential for deposit formation and must
be controlled by the fuel supplier.

Increased levels of detergent additives reduce the rate of injector plugging.

In case of plugging of injector follow the injector cleaning procedure mentioned in the
section below

3.5.2.14 Cleaning Procedure

Electrically disable the fuel pump by removing the fuel pump connection.

Relieve the fuel pressure in the system and disconnect the fuel connection at the
injector. Plug the fuel feed line.

Injector cleaner with the specific ratio of the cleaner and gasoline to be mixed in the
Injector cleaning tank.

Connect the injector-cleaning tank to injector in the vehicle.

Pressurize the injector-cleaning tank to system pressure.

Start and idle the engine for 15- 20 minutes.

CHAPTER 3 ENGINE PAGE. 3- 110

CHAPTER 3 ENGINE M565Li T3 EFI SERVICE MANUAL 20.0

Disconnect the injector-cleaning tank from the system and install the fuel pump
connections. Connect the fuel feed line to injector.

Start and idle the vehicle for an additional 2 minutes to ensure the residual injector
cleaner is flushed from system.

6.3 BRAKE SYSTEM SERVICE NOTES

It is strongly recommended always change the caliper and (or) the master cylinder as an
assembly. The parts inside maybe not interchangeable due to different brake manufactures
and (or) different brake type.
Do not over – fill the master cylinder fluid reservoir.
Make sure the brake lever and pedal returns freely and completely.

CHAPTER 6 BRAKES PAGE. 6- 2

CHAPTER 6 BRAKES M565Li T3 EFI SERVICE MANUAL 20.0

Check and adjust master cylinder reservoir fluid level after pad service.
Make sure atmospheric vent on reservoir is unobstructed.
Adjust foot brake after pad service.
Test for brake drag after any brake system service and investigate cause if brake drag is
evident.
Make sure caliper moves freely on guide pins (where applicable) .
Inspect caliper piston seals for foreign material that could prevent caliper pistons from
returning freely.
Perform a brake burnishing procedure after install new pads to maximize service life.

6.4 BURNISHING PROCEDURE

Brake pads (both hydraulic and mechanical) must be burnished to achieve full braking
effectiveness. Braking distance will be extended until brake pads are properly burnished. To
properly burnish the brake pads, use the following procedure.
1. Choose an area large enough to safely accelerate the ATV to 50 km/h (30 mph ) and to brake
to a stop.
2. Using hi gear, accelerate to 50 km/h (30 mph); then compress brake lever (pedal) to
decelerate to 0-8km/h (5 mph).
3. Repeat procedure on each brake system 20 times until brake pads are burnished.
(4. Adjust the mechanical parking brake (if necessary).)
5. Verify that the brake light illuminates when the hand lever is compressed or the brake pedal is
depressed.

WARNING
Failure to properly burnish the brake pads could lead to premature brake pad wear or brake loss.
Brake loss can result in severe injury.

6.5 FLUID REPLACEMENT/BLEEDING PROCEDURE

NOTE : When bleeding the brakes or
replacing the fluid always start with the caliper
farthest from the master cylinder.
CAUTION
Always wear safety glasses.
CAUTION
Brake fluid is highly corrosive. Do not spill
brake fluid on any surface of the ATV.

BRAKE BLEEDING-FLUID CHANGE

This procedure should be used to change fluid

or bleed brakes during regular maintenance.
1. Clean reservoir cover thoroughly.
2. Remove screws, cover and diaphragm
from reservoir.
3. Inspect vent slots in cover and remove any
debris or blockage.
4. If changing fluid, remove old fluid from
reservoir with a brake fluid pump or
similar tool.
NOTE: Do not remove brake lever when
reservoir fluid level is low.
5. Add brake fluid up to the indicated MAX
level on the reservoir.
6. Begin bleeding procedure with the caliper
that is farthest from the m aster cylinder.
Install a box end wrench on the caliper
bleeder screw. Attach a clean, clear hose
to the fitting and place the other end in a
clean container. Be sure the hose fits
tightly on the fitting.
NOTE: Fluid may be forced from supply port
when brake lever is pumped. Place
diaphragm in reservoir to prevent spills. Do
not install cover.

the reservoir to prevent air from entering the
master cylinder.
10. Tighten bleeder screw securely and
remove bleeder hose.
11. Repeat procedure steps 5- 9 for the
remaining caliper (s).
12. Add brake fluid to MAX level on reservoir.
Master Cylinder Fluid Level:
MAX level or
Sight glass must look dark, if sight glass
is clear, fluid level is too low.
13. Install diaphragm, cover and screws.
Tighten screws to specification.
14. Field test machine at low speed before
putting into service. Check for proper
braking action and lever reserve. With
lever firmly applied, lever reserve should
be no less than 1/2 " (13mm ) from
handlebar.
15. Check brake system for fluid leaks and
inspect al hoses and lines for wear or
abrasion. Replace hose if w ear or

7.2 BATTERY

Battery electrolyte is poisonous. It contains sulfuric acid. Serious burns can result from contact with
skin, eyes or clothing Antidote:
External: Flush with water.

lnternal: Drink large quantities of water or milk. Follow with milk of magnesia, beaten egg, or
vegetable oil. Call physician immediately.

Eyes: Flush with water for 15 minutes and get prompt medical attention.

Batteries produce explosive gases. Keep sparks, flame, cigarettes, etc. away. Ventilate when
charging or using in an enclosed space. Always shield eyes when working near batteries.
KEER OUT OF REACH OF CHILDREN

WARNING: The gases given off by a battery are explosive. Any spark or open flame near a battery
can cause an explosion which will spray battery acid on anyone close to it. If battery acid gets on
anyone, wash the affected area with large quantities of cool water and seek immediate medical
attention.

To ensure maximum service life and performance from a new battery, perform the following steps.
NOTE: Do not service the battery unless it will be put into regular service within 30 days. After initial
service, add only distilled water to the battery. Never add electrolyte after a battery has been in
service.
NOTE: New Battery must be fully charged before use.
1. Remove vent plug from vent fitting.
2. Fill battery with electrolyte to upper level marks on case.
3. Set battery aside and allow it to cool and stabilize for 30 minutes.
4. Add electrolyte to bring level back to upper level mark on case.
NOTE: This is the last time that electrolyte should be added. If the level becomes low after this point,
add only distilled water.
5. Charge battery at 1 /10 of its amp /hour rating. Examples: 1 /10 of 14 amp battery = 1.4 amp;
1/10 of 7 amp battery = 0.7 amp (recommended charging rates).
6. Check specific gravity of each cell with a hydrometer to assure each has a reading of 1.270 or
higher.

BATTERY INSPECTION / REMOVAL

The battery is located under the left rear fender. Inspect the battery fluid level. When the battery fluid
nears the lower level, the battery should be removed and distilled water should be added to the
upper level line. To remove the battery:
1. Disconnect holder strap and remove cover.
2. Disconnect battery negative (-) (black) cable
first,
followed by the positive (+) (red) cable.

CAUTION
Whenever removing or reinstalling the battery, disconnect the negative (black) cable first and
reinstall the negative cable last!
3. Disconnect the vent hose.
4. Remove the battery.

CHAPTER 7 ELECTRICAL PAGE.7- 3

CHAPTER 7 ELECTRICAL M565Li T3 EFI SERVICE MANUAL 20.0
5. Remove the filler caps and add distilled water only as needed to bring each cell to the proper
level.
Do not overfill the battery.
To refill use only distilled water. Tap water contains minerals which are harmful to a battery.
Do not allow cleaning solution or tap water to enter the battery. It will shorten the life of the
battery.
5. Reinstall the battery caps.

BATTERY INSTALLATION
1. Clean battery cables and terminals with a stiff wire brush. Corrosion can be removed using a
solution of one cup water and one tablespoon baking soda. Rinse with clean water and dry
thoroughly.
2. Reinstall battery, attaching positive (+) (red) cable first and then the negative (- ) (black) cable.
3. Install clear battery vent tube from vehicle to battery vent.
WARNING:Vent tube must be free from obstructions and kinks and securely installed. If not, battery
gases could accumulate and cause an explosion. Vent should be routed away from frame and body
to prevent contact with electrolyte. Avoid frame, corrosion will occur.
4. Route cables so they are tucked away in front and behind battery.
5. Reinstall battery cover and holder strap.
Do not start the engine with the battery disconnected. Vehicle lamps will burn out if battery is
disconnected during vehicle operation. Also, the reverse speed limiter can be damaged.

BATTERY TESTING
Whenever a service complaint is related to either the starting or charging systems, the battery
should be checked first.
Following are three tests which can easily be made on a battery to determine its condition: OCV
Test, Specific Gravity Test and Load Test.

MF (Maintenance Free) battery does not require the Specific Gravity Test and Refill

Open Circuit Voltage Test

Battery voltage should be checked with a digital multitester. Readings of 12.6 or less require
further battery testing and charging.
NOTE: Lead acid batteries should be kept at or near a full charge as possible.

Load test
CAUTION: Remove spark plug high tension leads and connect securely to engine ground before
proceeding.
NOTE: This test can only be performed on machines with electric starters. This test cannot be
performed with an engine or starting system that is not working properly.
A battery may indicate a full charge condition in the OCV test and the specific gravity test, but still
may not have the storage capacity necessary to properly function in the electrical system. For this
reason, a battery capacity or load test should be conducted whenever poor battery performance is
encountered. To perform this test, hook a multitester to the battery in the same manner as was
done in the OCV test. The reading should be 12.6 volts or greater. Engage the electric starter and
view the registered battery voltage while cranking the engine. Continue the test for 15 seconds.
During this cranking period, the observed voltage should not drop below 9.5 volts. If the beginning
voltage is 12.6 or higher and the cranking voltage drops below 9.5 volts during the test, replace the
battery.
