CHECK-UPS, ADJUSTMENT AND MAINTENANCE
Checking the Oil
Check the engine oil each time prior to operating the dirt bike.
The oil level should be between the upper and lower lines of the oil sight gauge located on
the right cover of the crankcase. The level can also be checked on the dip stick.
1. Set the motorcycle on level ground, look at the sight gauge for current oil level. Remove
the oil gage plug, wipe the oil gage rod clean and then insert the gage plug into the
crankcase again to check the oil level. There is no need to completely install the oil gage
plug in the crankcase fill hole.
2. Add lubricating oil up to the upper line when needed, but do not overfill.
3. Finally screw on the oil gage plug tightly.
CAUTION
Never start the engine when there is in sufficient
lubricating oil. Otherwise, it will cause harm to the
engine.
LUBRICATING OIL RECOMMENDED
The lubricating oil is an important factor
affecting the performance and service
life of the engine. Please refer to the
chart for the correct grade of engine oil
based on the environmental conditions
in your area. Do not use any other type
of oil other than what is recommended
in the chart. DO NOT MIX OIL WITH
THE GASOLINE.
Lubricating oils of different viscosity
shall be employed in different regions
and at different temperatures.

CHANGING THE OIL, CLEANING OIL FILTER SCREEN
1. of the engine and let the oil drain into an approved collection container.
DO NOT PERFORM THIS PROCEDURE WHILE THE ENGINE IS HOT.
SERIOUS BURNS COULD RESULT FROM CONTACT WITH HOT OIL.
2. Dispose of the used oil properly. For proper
disposal procedures, contact your local oil recycling
center.
3. Clean oil screen and spring with solvent.
4. Clean and replace the oil drain plug making sure
it is secure.
oil in the engine by using the oil gauge plug and/or
sight gauge.
CHECK-UP OF SPARK PLUG
1. Remove the cap of spark plug and screw off the spark plug
using the plug wrench.
2. Clean the spark plug all around or replace it if it is corroded
or there is too much deposit on it.
3. Regulate the gap of the spark plug to 0.6-0.8mm. (.024
inches - .032 inches)
The spark plug of the designated type should be used. The
applicable type of spark plug: D8RTC (Torch) or equivalent
VALVE INSPECTION
Refer to maintenance schedule in this owner’s manual for valve adjustment inspection
intervals .
Valve clearance should be:
Intake: 0.02-0.03mm
Exhaust: 0.03-0.05mm
The engine will make excess noise if the gap is too large in air valve. If gap is too small valve
operation will be hindered which could result in valve malfunction and failure. Therefore, air
valve gap must be checked periodically.
If you have the proper tools and are mechanically proficient, instructions on adjusting the
valve clearance are given in the service manual. If assistance is needed please contact Ricky
Power Sports LLC. to find your local service center.

16
CHECKING & CLEANING THE AIR FILTER
Air filter is located under left side plastic cowling.
Cowling will need to be removed.
Take the air filter out and check to see if it is dirty or
torn.
Remove foam element and wash with water and allow
it to dry per instructions below.
Apply a few drops of machine oil. Squeeze it with a dry
cloth to remove excess oil.
Recommended oil:
SAE 15W-40
CAUTION
The air filter element must be intact or the engine will suck in dust and dirt, resulting in a
shorter service life of the engine.
Water should be prevented from entering into the filter when washing the vehicle.
The filter element shall be cleaned gently without twisting to prevent it from cracking.
Never wash it with gasoline or any acid, alkaline or organic volatile oil to avoid its aging,
which will result in reducing the effect of the air filter oil to catch particles before they enter
the engine. Replace the element with a new one if it is broken or cracked.
ADJUSTING THE THROTTLE CABLE
Make sure the throttle works normally.
Check if the throttle twist grip has the required free operating movement.
The required free operating movement: 2-6mm (0.078 inches - 0.24 inches) If the grip
cannot be moved freely, turn the adjusting nut located on top of the throttle twist grip to
ensure proper operating movement.
After adjustment, start the engine and check for the operating movement again. Repeat the
adjustment if necessary until the desired operating movement is obtained.

17
ADJUSTING THE CARBURETOR

optimized and the user does not need to adjust it. If the idle speed
is indeed unstable, please go to the local dealer for treatment.
CAUTION
The vehicles have no adjustable operating parameter. Idle
screw is within 1500±100 rpm, so the range is within 100
rpm of default idle speed. The idle screw is covered by a
chock plug to prevent tampering by the consumer. OEM
guarantees all production vehicles will be installed with
prevent tampering device on idle screw to ensure idle screw
non-adjustable.
