Just changed mine two days ago after 3000 miles with mobil 1 v-twin and had 0 fuzz on the plug. Very happy with it.
Hoople if you really want to see what is being trapped in your oil, I cut the oil filter open after every third fill. As my 94FLSTC got more miles (over 70,000) I started to see more trapped fine metal.
That's a great idea Don. I still have the old removed filter so I will open it up just to take a peek. I have ~ 14,000 miles on the bike so far.
I really figured that having zero fuzz would be a rare sight but it seems to be out there in numbers.
Carefully spread the filter material on a surface where you can closely examine it..........where you want to look is not necessarily on the flat surfaces of the filter paper, but down in the pleats. That is where you will find anything that the filter traps.
If you're seeing stuff out on the flat parts of the filter material, you generally have found real trouble....and when you look in the bottom of the pleats, it will be loaded up.
Generally, on a good machine, you will find little or nothing.

Take a look at what I made to cut the filters open. Real easy to make...
