Maintaining a bike is not a big deal. Small things can just make your bike to be with you for years. Treat yr bike like yr Girl Friend.
Wash it weekly.
Change oil time to time. Every 1000-1200 as per your bike req
Service it time to time. Check corroborator, plugs etc.
If you feel that something is not right with your bike or it looks that bike is not working as expected, go to garage or service station.
