According to my old Chilton manual (1973 1st edition) it states on page 13 "There should be only a pint or so of oil in the sump."

So what is the expected normal residual oil in crankcase at the end of a normal ride.
I am wanting a documented amount of oil to expect in a Commando crankcase.
I can not believe the sump is pumped dry at all times. This zero quantity does not make sense.
Dont care about the crankshaft amount, altho fun to know about reference.

What is the normal amount in a Commando sump?
Don’t know how much help this is, but I’ve checked it on a Pre-Unit Triumph 650.

It was about a teacupful.

Aside from allowing for milk and sugar, is there an official measurement of a teacupful?
From Google:

" A teacup, often seen as a unit of measurement in Indian recipes, is about 190 mL, or ⅔ of an imperial (UK) cup. "

I just drained mine after a run. 2/3 of a cup came out. 1972 Combat engine. US cup.

I find it refreshing that we don't allow ourselves to resort to silliness in issues such as this!
Spot on chaps!

There are discussions of multiple subjects in this thread. On the subject of minimizing sumping, I am a little surprised no one has mentioned AMR’S work—putting an anti-sumping valve in the timing cover to minimize sumping through the pump, putting o-rings in the oil pump to minimize leakage at that location, and redirecting the flow from the oil pressure relief valve to minimize sumping from that source.

I got all three mods on my ‘73 850 and went from sumping so bad it emptied the tank in a week to minimal sumping in a month. I have a number of bikes so I might do a couple 100 mile rides on the Norton then park It for several weeks. This is what solved my problem. No more lying on the floor emptying the sump.
