B@lliZtiK: "Do they do things differently for motorcycle (4-stroke) oil? Or is the analysis basically the same. I'm just thinking because of there being significantly less oil capacity in a bike, certain contents will show up much higher on the scale, such as bearing metals, etc ..."

The process is the same ... but as you've guessed, you need to expect different levels of metal in your cycle sump samples.

The motor and tranny share the oil so you typically see a LOT more iron from the gears ... typically 25-50ppm instead of 5-10ppm. And, these same gears typically shear the oil down really quickly.
