An old non-computer literate friend has the above bike and wants to know
the correct oil for the primary chain case.
Some say engine oil....others auto transmission fluid.
He recently topped up the oil and found he could no longer turn the
engine over on the kick start.
Any help gratefully received.

what did he put in it?

has to be possible that it's fought with what's in there.

consensus here (mind, neither me nor Father has ever had an A65) is engine
oil, on the basis that sooner or later you'll get a leak one way or the
other :-)

when he says "can't turn it over" is this "it feels a bit stiff" or "it's
locked solid"?

too-heavy oil might be a problem, but I doubt engine oil comes into that
category. EP90 or something might.

I wonder if it shoud be lighter? From memory my Norton takes 30 in the
primary and 80/90 in the gearbox.

Well, with the Bonnevile I had at one point, it was engine oil. With a
wet clutch you really do not want something with high viscosity like
EP90.

I wouldn't recommend it for road use but I ran a racing sidecar outfit (750
Suzuki two-stroke triple) with EP-90 in the transmission for 3 seasons. It
was a bitch to free the clutch first thing in the morning but, after that,
it worked fine. It ran the same clutch plates for the entire three seasons,
which is more than I can say for just about every other engine component.

Probably the oil is too thick (heavy) or he may have just put too much in
and it has got on the clutch plates and making it slip when he tries to kick
it over. Drain it out or remove the cover, dismantle the clutch and wash the
plates in petrol or degreaser and try again. Can't think of any other
problem caused by just putting some oil in.

Heh. I recall a housemate telling me that the gearbox oil was draining
terribly slowly out of his bike. I turned out that he'd mistaken a
relief valve or a selector indent plunger (I forget which) for the
drain plug.

You might be right....... if it was a two smoke with drive side crank oil
seal gone. :-)

If locked solid, that would suggest hydraulic lock...

He has probably used something with lots of extra slippery additives. The
clutch may now be slipping because the plates can no longer grip properly.
