Harley 4 speed tranny is hard to find neutral

total loss= you put oil in the oil tank. this oil would lube the engine, primary chain,rear chain. as the rear chain and primary chain were not in sealed housings, the oil would drip to the ground. the amount of oil sent to these chains was adjustable, but it still went to the ground. if you never added oil, it would eventually run dry.......so, it is a total loss system. your 83 was a sealed system, and should not have leaked oil. 65=1965 big twin

Total loss = Dry sump

same thing, as explained above

One reason is that oil, pooled around the flywheels
causes severe drag and kills power.

Having enough to keep it cool and
wet on the bearings and joints and surfaces
is sufficient.

HD's , Race Cars etc are dry sump or total loss...

Look at an HD, on touring the oil resevoir is under the trans
on a softail it's under the seat, that's where you keep oil

Now if the oil is kept there, it's returned to that container
during use

So the oil flows to the engine from the tank, is pumped through
ports and holes to provide lubrication, then back to the tank.

Now look at your car, it has an oil pan on the bottom,
all the oil is pumped up from that pan, like a sump pump in a basement
up north.

Dry sump means the engine doesn't hold the oil, it's held elswhere.

pretty much, oil is kept out of the working internals of the engines
for storage purposes, lubrication is delivered by a pump constantly
to provide a thin film of oil to the places that need oil.

In a typical small block oil was contained in a bath (oil pan) at the
bottom of the engine and the crank would dip into it to sling some oil up on the bottom
while the pump pushes oil up top, all oil uses gravity to return...

With the oil in the crankcase it creates drag, which reduces power, increased work required to overcome the drag and robs power and mileage.

If you hear someone telling you your HD engine is sumping it means the oils gathering
in the bottom of the cases around the flywheels and if it happens you will
know because power will go lower big time fast...

not so sure about that hrk.....dry sump and total loss are different. dry sump would mean that oil is not stored in the sump, but in some place else...an oil tank. total loss would mean that once oil is added, and never refilled, at some point in time there would be no oil left in the system as it all leaked, pumped out.......a dry sump will always have oil if no leakage occurs.........

Well you beefed up the engine, might as well beef up the trans...

Yes I run the Jims trap door on my 124
after it pulled the bearings through the stock trap.

yes hd stock 5 speed in stock cases

Yes 124 Twin cam, built by SNS (several times due to some "assembly" issues)
woods 505 rebel CV carb Custom intake from Wes in Pinellas Park IST ignition SNS,
and heads ported and cleaned up by Bill at Bishops Performance in Detroilet.

and when he starts it up, i can hear it over here in Texas!!!!!!
