NOTE:
The difference in compression pressure between cylinders should not exceed 100 kPa (1 kg/cm2, 14.22 psi).
У If the compression pressure is above the maximum specification, check the cylinder head, valve surfaces, and piston crown for
carbon deposits.
Carbon deposits → Eliminate.
У If the compression pressure is below the minimum specification, pour a teaspoonful engine of oil into the spark plug bore and measure again.
Refer to the following table.

CHECKING THE ENGINE OIL LEVEL
1. Stand the scooter on a level surface.
NOTE:
Х Place the scooter on a suitable stand.
Х Make sure that the scooter is upright.
Ш Start the engine when the engine is cool, let it idle for two minutes, and then stop it.
Ш Wait two minutes until the oil settles, and then check the oil level through the check window located at the bottom-left side of the crankcase.
Ш Check:
engine oil level
The engine oil level should be between the minimum level mark a and maximum level
mark b.
Below the minimum level mark → Add the recommended engine oil to the proper level.
Recommended oil
Refer to the chart for the engine oil grade which is best suited for certain atmospheric temper-atures.
API standard
SE or higher grade ACEA standard
G4 or G5
CAUTION:
Щ Engine oil also lubricates the clutch and the wrong oil types or additives could cause clutch slippage. Therefore, do not add any chemical additives or use engine oils with a grade of CD c or higher and do not use oils labeled “ENERGY CON-SERVING II” d or higher.

Щ Do not allow foreign materials to enter the crankcase.
CHANGING THE ENGINE OIL
Ъ Start the engine, warm it up for several min-utes, and then turn it off.
Ъ Place a container under the engine oil drain bolt.
