The oldest topic amongst Harley riders, since i can remember !
OIL ! & OIL-PRESSURE !
Any engine needs oil , period.
Basically, Harley's don't need oil-pressure,
they just need "a flow of oil".
So there goes "your interesting nonsense bar talk."
Here is why;
Early Harley's had a Total loss oil system.
When ya stopped in the 1920's at a gas-station ya fueled gas and oil !
Total loss ?
Yeah, the oil was allowed to drip out of the engine.
People tried to minimize it as much as possible,
because it gave such a
mess on their pants, boots, jacket.
( airplane pilots, on their goggles)

| 1929 JD, the oil under it ? JD Total loss oil system= normal ! |
Harley made a dual pump in 1936 ( feed and yes, now a scavenge side 2 )
 |
| knuckle oil pump |
Basically; so it did "not" over oiled the engine and THE riders pants.
THE first need for a bit of pressure was in 1948 with the introduction
of the Panhead. Harley did not realize hydraulic push-rods needed some
pressure. They just added hydraulics in the push-rods up with the rocker-arms without an proper oil pump adjustment.
No need to tell,
trouble !
That's why solid after market push-rods replacements, like
s&s became popular.
By the way Sportster's had solid push-rods up to
1985 !?
Ya wonder why ?
Ya see, the only reason, an Harley engine
needs some kind of oil-pressure is because of the hydraulic push-rods.
So all the big twin engines,
up to 1999 could run with an Knucklehead oil-pump,
as long ya replaced THE hydraulic push-rod units, for solids.
Crazy hey !? But true !

| Ultima high performance pump $$$ |
So why, oh why ?
is there so much offerings in the so called " better"
oil pumps
who can yield your oil pressure to THE sky !?
Well remember
"your interesting nonsense bar talk"
about oil pumps from the beginning ?
 |
| Please. Buy this oil pump !? | | |
What a way to make money,
produce THE oil-pumps they talk
about & wish,
and you can make money !
Anecdote; a friend from me
( Dale Nungesser) a top-fuel dragracer out of
Kansas,
makes his own crankcases ( sells 'em too),
without the possibility to mount an oil pump.
I asked him " come on Dale, why?"
His
answer was plain and simple,
" the oil-pump takes horsepower from my
engine,
and i don't need the oil pump".
Well Dale ya NEED oil !
Correct; just made some 'ol style lube-points on it ,
give it a squirt or 2, that's enough for à 1/4 mile, 500 hp. dragbike.
Dale ran, some 6,8 secs with an end speed just over 200 mph, and he
relied on just a few squirts of oil, an never ruined an engine due to oil-problems. Case closed .

Oh, and French fries are cooked in oil ! :-)

| Mineral, vegetable, synthetic oil? Did they used this ? to lube those motorcycles back in the 1920's ? | You would be surprised ! |
