The two most important aspects of four-stroke maintenance are frequent oil/filter changes, and regular valve clearance checks/adjustments. And some four-strokes (RMZ450 for example) have a manual timing chain tensioner that must be regularly checked/adjusted. Everything else is exactly like a two-stroke.

Very important... valves get out of adjustment and are easy to set. This is where I would start FOR SURE. Check out www.buggiesgonewild.com and an example of how to do it on EZ GO 295 http://www.buggiesgonewild.com/ezgo-gas-tech/1196-ezgo-295-350-engine-valve-adjustment.html
SOURCE: where do you drain oil on 1997 yamaha fzr600 and
the plug to drain the system is on the very bottom of the crankcase, and yes the oil you have is good enough, i prefer full synthetic but that is optional.
