Engine oil filter

[TK4]

you never did that?

No, but I've done a fair bit of work on CBR125Rs - they don't have a replaceable filter just a screen at the pump pickup.
The muck that comes out of those things is disgusting.

oil particle count
before and after filter change
is the only definitive way to verify level of filtration
never heard of anyone doing that on a bike

get into larger, more $$ equipment
and some units have a particle count sys built in

Wet clutches don't help things.
Take something like a dry clutch Ducati or a Harley with a split engine/primary/transmission oiling system and the results would be radically different.

I think oil analysis like through Blackstone is the only real way to see how your oil (and motor) is doing, but that doesn't necessarily mean the filters are better or worse.

Perfect when you are looking at having to replace 65 gallons of oil in an excavator.

14,000 litres of hyd oil
don't want to be throwing that away too often
they have particle count systems built in
