Frequently Asked Questions - 250 SER (2019) Sherco

What fuel/oil mixture to use?

Use unleaded premium gasoline with 98 octane rating mixed with 2% 2-stroke engine oil. For example, for 10 liters of gasoline, add 200 ml of oil.

How to adjust the chain tension?

Place the motorcycle on a stand. Measure the slack in the middle of the chain: it should be between 50 and 53 mm. If necessary, loosen the rear axle nut, the lock nuts, then adjust the tension screws on both sides symmetrically. Retighten the lock nuts and tighten the axle nut to 100 Nm.

Which engine oil to use and how much?

Use SAE 10W40 oil (e.g., Minerva). The capacity is 750 ml (0.75 L) for the gearbox. Check the level with the control screw on the crankcase.

How to bleed the fork legs?

It is recommended to bleed every 5 to 10 hours of use. Motorcycle cold, fork fully extended. Remove and retighten the bleed screws located on each fork cap. This evacuates the accumulated air under pressure.

How to adjust the suspension (fork and shock)?

For the fork, adjust compression and rebound via screws at the bottom (WP) or top (Kayaba). Turning clockwise increases hydraulic damping. Base settings are given in clicks (e.g., comfort 18 clicks, standard 15, sport 12). For the shock, adjust low-speed and high-speed compression, as well as rebound, with specific screws. Check static sag (30 mm) and rider sag (95-105 mm).

Where are the frame and engine serial numbers?

The frame number is stamped on the right side of the steering head. The engine number is stamped on the rear part of the right central crankcase.

How to start the cold engine?

Put the selector in neutral, activate the choke (pulled up), press the starter button without accelerating. Let it warm up for a few minutes, then deactivate the choke. For a hot engine, follow the same steps without choke.

How to replace the headlight bulb?

Remove the headlight plate by unclipping the rubbers and disconnecting the connector. Remove the rubber cover, turn the socket a quarter turn counterclockwise to extract it. Press the bulb while turning it to remove it. Install a new one (S2 12V 35/35W) and reassemble in reverse order.

What tire pressure for off-road use?

The recommended pressure for off-road is 0.9 bar (about 13 psi) for both tires, front and rear. Always check when cold.

How to maintain the air filter?

Remove the seat, unscrew the knurled screw, and take out the filter with its support. Separate the filter from the support. Clean the foam with a special cleaner (no solvent or gasoline). Let it dry, then soak with air filter oil. Reassemble ensuring proper centering and greasing the front face. Reinstall the knurled screw and the seat.

■ KEYLESS System

The bike has a "Keyless" system.

It allows the bike to start without any key or ON/OFF switch.

It automatically turns on and it turns off after 30 secondes of no use of the bike.

When the motorcycle is not used for a long time or during a strong cold (<10°C) the lithium battery can go into sleep.

To wake her up, press few short blows on the starter button.

■ Motor emergency stop button (250-300 SE/R)

ATTENTION

• The hot liquid can cause severe injuries.
• The coolant is harmful
• After contact with skin or eyes, or ingestion, or injuries caused by hot liquids: Consult a physician
• Use protective gloves.
• Do not replace the coolant with water or other not approved fluids: it could damage your engine.
• Follow these procedures carefully and always fill the engine with coolant when the engine is cold.

- Place the bike upright on a horizontal surface.

- Remove the cap ①.

Fill the radiator full so that there is no air in the system.

Approved Coolant

Fill the coolant to the top of the radiator.

Replace the cap ① and check to make sure it is tight.

ATTENTION

It is important to follow this procedure.

The lack of fluid, or the presence of a pocket of air left in the radiator can cause serious damage to the engine.

With the handlebars facing straight ahead, check that the throttle twist grip functions properly.

Throttle cable play 2....4mm

If the cable play is not correct, adjust the accelerator throttle cable play. (below)

Start the bike and let it run at idle. Turn the handlebars and check that the idle speed is constant. If the speed changes, readjust the play in the throttle cable. (below)

■ Adjusting the play in the throttle cable

SETTING THE IDLE SPEED

• The idle speed is adjust with adjusting screw ^1
• The idle mixture is adjusted with the idle air adjusting screw ②.

Start the bike and allow it to reach operating temperature.

Adjust the idle speed by turning the air screw 1 2200 +/- 100 rpm

Turn the adjust screw idle mixture all the way and turn it to 1 turn 1/2.

Idle speed 2200 +/- 100 rpm

SETTING THE CARBURETOR

How the opening of the throttle slide influences performance:

The composition of the mixture (Air-Gas) is a function of the opening of the slide:

A: Idle range

From 0 to 18 opening of the throttle slide, this range is regulated by the idle screw ① and the air screw ②.

• B: Transition range

From 18 to 14 opening of the throttle slide, this range is regulated by the idle jet and the shape of the slide.

C: Mid-range :

From 14 to 34 opening of the throttle slide, this range is regulated by the needle valve (shape and position). In the lower range, the idle circuit, and in the higher range, the main jet take into account the control of the motor.

D: Full load

From 34 to full throttle slide opening, this range is controlled by the main jet and the needle jet.

Washing and storage

WASHING THE BIKE STORING THE BIKE

SHERCO advises you to wash your 250-300 SE/R as often as possible in order to maintain it in good working order and prolong its life.

1. Cover the end of the exhaust silencer and the air filter (plastic bag, special cover or a special cap).
2. To degrease the engine, apply a degreaser, clean with a brush then rinse the engine with a water hose.
3. Wash the rest of the vehicle with hot soapy water.
4. Rinse with clear water.
5. Dry with a chamois or a clean, soft cloth.
6. Clean the chain and lubricate it with a special chain lube.
7. When the cleaning is finished, remove the air filter and exhaust protection, Start the engine and let it run atidle for a few minutes.

Avoid using high pressure equipment which may cause water to leak into the bearings and fork seals and cause serious damage. Use an average strength detergent rather than a strong detergent.

CAUTION

In order to avoid any water ingress, keep a minimal washing distance of 20cm.

Before storing the vehicle Long-Term (more than 2 months), follow these instructions :

1. Wash the whole bike.
2. Empty the fuel tank.
3. Remove the spark plug and inject a protective spray inside the engine through the hole in the cylinder. Install the spark plug. Cycle the engine a few revolutions to apply a protective film on the cylinder walls.
4. Remove the battery (p.126)
5. Charge the battery (p.127)
6. Lubricate all cables with a spray lubricant.
7. Jack the motorcycle up so that the wheels are off the ground.
8. Cover the exhaust outlet with a plastic bag to prevent moisture from entering.
9. Spray a protective oil film on all unpainted metal surfaces of the motor and also on the electrical wiring.
10. Cover the motorcycle with a cover.

RECOMMISSIONING AFTER STORAGE
