No Oil!!

I bought a ktm 640 LC4 about 6 weeks ago. I brought it home from
Coventry and put it in the garage. I was going to use it for work but
with one thing and another i only taxed it the other day.
I have used it for work about 5 times and only got round to checking
the oil today (kept forgetting) I thought there was a oil light. If you
look at the clocks there is a oil light but it dosent come on and it
says in the book this light does nothing!!!
I couldnt see any oil through the sight glass!!
I have put about 1Ltr in it and that has brought it back to the right
level.
It says in the book that it takes 2.1Ltrs of oil in the frame and
engine.
Will i have done any damage?
Would it of seized if there was no oil getting round it? Its about 10
mile around trip to work and back
It says in the book use only fully synthetic oil but i couldnt get any
on a sunday afternoon the only thing i could get was semi. Will this be
ok untill i can get to the bike shop?

Cheers for any help
Rob

 

You will probably get away with it unless you are going to thrash the
tits off of it all the time. What you do need to do is make sure that
you follow the prescribed filling technique should you ever do an oil
change yourself. You do not want an air-lock between the oil-in-frame
tank and the engine.

From the KTM manual ...

"Changing the engine oil (models with frame oil)

NOTE: For improved cooling of the engine oil, the front tube of the
frame was integrated into the oil circuit. Thus, when you change the
oil, you also have to drain the engine oil from the front tube and bleed
the oil system.

If the oil system is not bled at all or bled insufficiently, the
bearings of the engine will not get enough lubrication, which in turn
may result in engine failure.

The engine oil change is to be carried out when the engine is still
warm."

and later (their capitals, not mine) ...

"– ONLY USE HIGH-QUALITY OILS MEETING OR SURPASSING THE QUALITY
REQUIREMENTS OF JASO T903 MA (FOR SPECIFICATIONS SEE CONTAINERS).
– INSUFFICIENT OIL OR POOR QUALITY OIL RESULTS IN PREMATURE WEAR OF
THE ENGINE.
– YOU MAY USE EITHER MINERAL OILS OR SYNTHETIC OILS FULFILLING THE
ABOVE CRITERIA."

 

Wot he said. Dry sump innit.

 

In uk.rec.motorcycles, belched forth and ejected the following:

You did have the bike in an upright position when checking, I.e, not on
the stand?

You'd have done more damage thrashing it from cold. In ten miles it's
only just got warm enough to pull wheelies on, imho.

I mix grades. KTMs have a ridiculously short service interval so
personally, I don't see a problem.

 

Just for info, my Duke-II interval is 4,000 miles.

 

In uk.rec.motorcycles, Tim belched forth and ejected the following:

4,000 is ridiculously short. I grant you, my XY, while not in the
superbike of motos, is 6,000, I'd never let it run that long withat
least a change of oil.
