A regular cartridge oil filtration system generally has some sort of
pressure sensing bypass designed in. Either in the filter itself or in
the oil pump and passages. If the oil is too thick, too cold or the
filter is too dirty, the oil supply bypasses the filter and continues to
lubricate vital parts.

The filter proposed here has no such bypass. If you leave it for
"longer duration between changes", you risk having the filter medium
blocked up and the engine starved for oil. How many old loops went
hundreds of thousands of miles without anything but a bug screen to
filter oil? Sounds maybe risky and at least debatable. Wonder how long
he is recommending exchange intervals? And if he is using Dyno or
Synthetic oils?

When Guzzi first came out with the in-pan filter on Tonti frames, I knew
a guy who had moved up from a loop. He decided the filter exchange was
a hassle. He removed one, blew out its guts, and re-installed the
cartridge shell so that it would work like his reliable old loop had done.
