Firstly; letting us know how many km's on it would help!

As the manual states:
*Every 6000km or 6months*
Check idle speed
Check clutch free play
Check spark plugs
Lubricate all levers, pivots and cables
Change engine oil (Recommend every 5000km)
Clean air filter
Check wheel and tyre condition
Check coolant levels
Check brake pads, fluid levels and lights

*Every 12,000km or 12months*
Change engine oil and filter (Recommend every 10,000km)
Check fuel filter and fuel lines for leaks
Check battery terminals
Check choke and throttle cables
Renew spark plugs
Check carburetor synchronization
Check headlight aim
Check side–stand spring
Check suspension (front and back)
Check steering head & wheel bearings
Check the tightness of all nuts, bolts and fasteners
Change brake fluid
Check valve clearances
Check chain and sprocket condition
