Chain lubing…well, every 1000kms (600miles) is the norm…but if you ride in the rain, or very dusty & dirty conditions I would clean/lube the chain after each fill of the tank…
Keeping the bike clean is another good one that people miss…as you are cleaning you may notice things that need to be adressed…an oil leak before it drips on the floor, a frayed cable, etc…
I usually lube my cables every 5000kms (3000miles), check the hoses for cracking and change your oil and filter around that time as well…if you don’t ride that much in a year, I would do those things atleast once per year.
Check the electrolite level in your battery once per year…there is usually a line on the battery to show where the liquid should be (above the line)…but if not, just make sure the plates inside the battery are covered by about 5mm (1/4″)
I was going to mention valve adjustment intervals, but I really don’t know that much about the Kawi’s…best advice is to pick up a Clymer or Haynes manual for your bike…they have a maintenance section that will give you an outline to follow…and explain in plain terms how to perform the work…
Good Luck!!
Later.
