Irregular Maintenance
1. Ignition System: if ignition failure, engine overheating or engine stalling problems are
noticeable and occur constantly, perform maintenance and inspection.
2. Remove Carbon Deposits: If the horsepower of the engine decreases considerably,
remove the carbon deposits in the valve, piston, throttle body, idle air bypass valve and
fuel injector.
3. Drivetrain: If the top speed drops considerably, perform maintenance and inspection for
the CVT parts and replace them when necessary.
4. Fuel Injector: Please remove the carbon deposits or gummy residues inside the fuel
injector when the vehicle has not been operated for a long time.
5. Fin/Front Protection Screen of Radiator: Check and clean it every 1000 km. Perform
cleaning and maintenance as early as possible if driving in dusty and rainy areas.
6. ABS Wheel Speed Sensor/Reading Disc: Perform maintenance and inspection every
5000 km. Replace the sensor when necessary.

Notes
1. We recommend that you add a bottle of KYMCO fuel injector cleaner every 1000 km to
the fuel tank.
2. An air blow gun must be used to clean the dust and foreign objects inside the belt wheel
for models with rear wheel driving belt. Check the belt for crack or fracture and replace it
when necessary. Check whether the tension of belt is within the specification. Adjust it to
the range within the specification when necessary.
3. If the vehicle is often running in dusty areas, clean and replace the air element more
often for longer service life.
4. To ensure fuel efficiency and mechanical performance of the vehicle, be sure to perform
cleaning and maintenance for fuel injector, throttle body, valve clearance and air filter
based on the mileage (or month).
5. It is suggested that the maintenance item marked
★
must be performed by a KYMCO
dealer.
