If I remember correctly, after 50+ pages on the old site, http://avlube.com/mob1mx104cyc1.html this was the oil to use. 

I use the 4t and Klotz.  Both are more than acceptable.

Quote from DP

Unit construction refers to an engine and gearbox in the same cases.

It was a selling point of the 60s and 70s Triumphs and BSAs over Norton that used a separate gearbox.

It definitely poses different lube requirements.

For the sake of historical accuracy I think the plot thickens even more since the unit construction Triumphs and BSA's still used separate compartments within the unit case for engine oil and gearbox oil - unlike our Duc's the two lubes did not intermix.   The main selling point for the unit construction was getting rid of the external chain between the motor and the gearbox.

I know this is an oil thread, and should not be encouraged...but I've always wondered just how much difference there actually is between all of these different specialty oil products you see on the shelves these days. Does the additive package used to turn regular Mobil 1 into "V-twin" oil (for instance) really justify the extra cost?  Especially if you change your oil well before the stated service life is up, as almost everybody here seems to do?

dig around on the web, there are a few engineers who have taken off-the-shelf oils and compared them chemically

yes, there is a difference is the upshod, but hte differences may be minimal.

howver, recent changes to oil to meet EPA requirements may have affected the difference and it may be greater.

My Honda Civic has 193k miles on it.  I've used every kind of oil in it: Jiffy Lube, good name brand dino, expensive synthetics, high mileage varieties, generic cheap store brand recycled.  Compression is great and it runs just fine.  For this reason I think regular oil and filter changes are more important to engine life than the specific oil.

Now there are some oils you should definitely not use with a wet clutch.  Beyond that, some oils are probably a little better for motos than others.  Does anyone know of anyone who had a moto engine or transmission failure in any bike related directly to the choice of oil?  If not, it's probably less important than all the oil thread make it out to be.

I don't think failure is the main problem.  I bought a honda CB350 years ago that had a slippy clutch and the gears wouldn't shift right.  It just felt effed up -- the guy sold it to me for 200 bucks thinking it was a bad gearbox.  He had changed the clutch plates several times and it was still slipping.

I did what I always do when I can't figure out what's wrong:  Change the oil.  I don't know what he had in the box, but I put in a moto oil, I think it was Valvoline 4T, I don't remember.

Long story short, the problems disappeared completely after about 20 miles.  it was like night and day.  I never bothered asking what oil he put in, but something tells me he bought his 10w40 car oil by the gallon and just threw that in.  Many car oils are "energy conserving" and will make your wet clutch slip like an old whore.

Absolutely!  That's one of the cases where a non-moto compatible oil was put in.  That's bad.  And some bikes/clutches are more sensitive to it and should be treated accordingly.  Even two bikes of the same year and model may behave differently.

For me, I felt no difference at all between Motul moto oil and Mobil 1 car oil.  I had tried Motul specifically to see if the tranny and clutch would feel any different, they didn't.  In a case like that, I don't know that it makes any significant difference.

Back in the day

we worried about our 2 smoker trannys.

At the time the hot set up was Spectro Golden gear.

Keep in mind it was tranny/clutch only.

We ran 2T in the motors.

Spectro is good stuff.  The only oil I ran in my 2 stroke saabs (besides genuine saab oil) was spectro golden

i picked up some oil down at AMS recently. Marty sold it to me because its the "double ester" blend. I asked "what's that mean?". "It has more ester."  hahaha, right.  whatever, dump it in and worry about something else more important.
