Should the transmission box be cleaned periodically for scooter model ?
The CVT transmission system functions through the drive belt. The ash of belt and dust might accumulate on front or back pulley due to rubbing, so the transmission system should be cleaned every 3,000km, or there might be slippage at drive belt or rear driven pulley.

What are the points of attention to Electronic Fuel Injection model machine ?
1. Never apply large throttle when engine has no workload .
2. Any electrical modification is strictly prohibited.
3. In order to keep sufficient power supply, check battery every 2,000km.
4. Clean the throttle and injection nozzle every 3,000~5,000 km.

What should I notice after changing cooling liquid ?
The radiator cap should open after exchange, to ensure the air had been totally expelled, The coolant level would drop if air mix in pipe line after apply throttle slightly.

The possible reasons are listed below.
1. The inappropriate adjustment of air/fuel mixture.
2. Slippage occurred in the clutch weights.
3. Oil leaking in the transmission box.

Why should the 4 stroke engine oil be exchanged every 1,000km ?
The engine oil is the key material to lubricate the engine system, its crucial to use and exchange it periodically. The owner should use the specified type of oil regulated by the manufacturer, to fit the requirement of product warranty criteria.

The frequency to exchange engine oil depends on descriptions shown on the owner's manual.

But, its for sure that to perform checks and maintenance periodically would improve the product's performance and life.
