I will add a little side story.
Most British motorcycle pre 1980 used a centrifugal oil filter inside the crank, commonly called a sludge trap in conjunction with a settleing tank + a ew gauze screens to protect various devices.
The recommended time between bottom end rebuilds is 30,000 miles, mainly to clean out the sludge trap.
A riding friend has a bike that would not hold pressure at idle, a sure sign that the previous owner had not done the bottom end work.
Well he was a sailor who did regular coastal work so it was 6 days on & 6 days off.
HE changed the oil every time he rode the bike ( usually on a 4 to 6 day ride ) and the clean looking oil then got used to do an oil change in his F 250 truck.
120,000 miles latter he sold the said same bike with exactly the same low oil pressure problem that it has when he bought it.
as another riding pal used to say
"Oil is the cheapest part you can put into a motor"
