If you want to get real scientific/anal about it, flush the filter into a clean container, let the solvent flash of/evaporate, dump the filtered material onto a clean surface. Then take a piece of scotch tape large enough to cover all the particles and pick up all the particles and then stick the tape (with all the metal attached) into the front page of your manual with the date. This way you can compare from one filter change to the next how much metal your engine is making.

You have to remember that some guys on this forum change their oil each 2 or three rides so it is normal for them not to notice those little pieces of metal.
As I don't race, I change my oil each 1000Km as the user manual recommands.
I'm also planning to contact Yamaha about it and have a final word from an engineer.
If any of those eng is reading please...

So, Don't sweat the little stuff. Take care of them and you'll find that they are "Bulletproof".

These 4 strokes have much more bottom end torque and they do not need ,nor will they tolerate alot of clutch slippage due to the hot oil and hi torque. The only time I slip the clutch is on the start from a dead stop. Any excess clutch slippage will contaminate your engine oil. Not a good thing for your motor!
I clutch the hell out of my bike when hill climbing or technical single tracking etc. You pretty much have to clutch when on a gnarly hill! I have never had one bit of problem, the oil doesnt look any different whether Im on the clutch or not. After the first few changes there is still the same amount of metal particles on my oil filter no matter what(just a pinch or so). Sure clutching your bike will wear out a clutch over time, but its not life threatening. Just ride it like you stole it!

Here's about what I find (more or less) each oil change. Changes usually between 150 and 250 miles.

Thanks John, a picture is worth a thousand words, its about exactly what mine looked like. And to answer those others regarding clutch, I'm easy on a clutch, never worn one out in my life and I always use the clutch when shifting, I know many who dont. And freeplay is always perfect. I can feel that when I pull the lever. As a toyota tech by trade, I'm pretty up to speed and I see bits and pieces on the diff and tranny magnets all the time. You guys told me what I wanted to hear, feel much better now. Thanks for all the nice input.
