The fuel should be an easy 1 to figureout without a diagram.
Gas tank -> petcock > fuel line -> fuel filter -> fuel line -> carburator
The oil lineż Should have a breather tube that goes from the crank case to either the air box or a filter on the end of a tube. Drain plug is on the bottom i imagine.
I don't think they have oil filters, i looked up on ebay for a replacement filter - no go. But i know my klt200 has a paper filter(very different engine), and my Honda 200m has a filtering screen. I don't know about the klt160 though.
I just wanna go fast. If your not first, your last!!
