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.
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
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.
