  2. Two stroke oil is held in a reservoir located behind right hand radiator shroud.

  3. To remove oil filler cap, you must first remove the radiator shroud by taking out the two (2) screws and one (1) bolt.

  4. By releasing the steel clip, you can remove the oil filler cap.

  5. Use only a high quality two (2) stroke oil.

  6. Fill reservoir to oil level gauge indicated on upper part of reservoir. (Refer diagram).

<LLi Notes.

The engine, the muffler and the exhaust pipes are extremely hot after stopping the engine.

Transmission oil should be checked as part

of your pre-ride inspection.

  1. To check transmission oil, hold bike in an upright position. Ensure bike is on level ground.

  2. Remove check bolt.

  3. The oil level should be up to the lower threads of the check bolt hole.

  4. To add oil, remove filler cap and pour in the recommended transmission oil until it is at the correct level.

Transmission Oil

Advice

The engine oil also lubricates the clutch. Use of engine oils designed to reduce wear and tear on the engine could cause the clutch to slip, affect engine start up, degrade engine performance and even shorten the engine life.

Do not use oil additives designed to reduce engine wear and tear.

Transmission Oil

Oil change intervals.

Initial: 1,000km After the first change:

Every 6000km

Contact an Authorized Honda Dealer for the oil change.

(SAE Rating)

-10 0 10 20 30 40°C Outside Temperature

Temperature and Viscosity

Choose the Transmission oil corresponding to the atmospheric temperature in your riding area.

  1. The Honda CRM250 has a liquid cooled engine, Coolant level should be checked as part of your basic maintenance.

  2. You can do this by visually inspecting the coolant level, behind the left hand side cover.

  3. Make sure bike is on level ground and ensure that coolant level falls within the upper and lower graduations.

Z^Caution

Do not remove the radiator cap while the engine is hot. Coolant can spurt out, causing severe scalding.

Allow the engine and radiator to cool before attempting to remove the radiator cap.

54

Coolant

Reservoir

Adding Coolant

  1. To top-up the reservoir, you must first remove the seat and left hand side cover.(refer page 22)

  2. Remove filler cap and fill reservoir with Honda Ultra coolant to level indicated on reservoir.

  3. If level drops significantly, it may mean there is a leak in the cooling system.

Contact an authorised dealer for technical

support.

Advice

Use of poor quality water or radiator fluid other than the recommended type will cause corrosion / electrolysis.

55

Drive Chain

  • Chain Slack Check >

Place the motorcycle on the side stand and pull the chain up and down at the mid-point between the front and the rear sprockets. Measure the slack using a ruler.

Drive chain slack: 30 ~ 40mm

Adjust the slack if out of the range.

Never ride the motorcycle if the slack is 60mm or more.

Roll the motorcycle back and forward to observe the chain.

If the chain is jerky or noisy , have it serviced / replaced.

Contact an Authorized Honda Dealer for the adjustment or the replacement.

Drive Chain

  • Lubrication and Cleaning >

Place the motorcycle on the side stand and clean mud or dirt from the chain and sprocket.

Move the motorcycle back and forward to clean entire chain.

Avoid steam cleaning as the chain has rubber seals.

Apply lubrication oil to both sides of the chain roller so as to have the oil reach entire part of the chain.

Excessive lubrication may result in spattering oil on the body or on your clothing.

Chain Oil: “Genuine Honda Chain Oil”

Or gear oil (#80 ~ #90).

Advice

Do not use chain spray and other lubrication oil containing solvents. They may shorten the life of the chain.

Brakes

Front Brake

  • Brake fluid level check >

Place the motorcycle on flat surface and set the side stand. Move the handlebar to make sure the reservoir cap surface is level

Check the fluid level is above the lower limit line (minimum line).

If the fluid level is below the minimum, brake pads may be worn. Check the pads

If the brake pads are fine, there may be a leak in the brake system. Refer to p 60

Contact an Authorized Honda Dealer.

Fuses

  • Fuse inspection / replacement >

Stop the engine before checking the fuses. Replace blown fuses with the fuses of same rating.

Never use higher-rating fuses. They may cause overheating and electrical system damage.

If a new fuse blows soon after replacement, there may be a fault in the relevant electrical system. Locate and repair the fault before installing a new fuse.

Advice

Replace the electrical parts only with genuine Honda accessories.

Other parts can cause fuses to blow.
