Idled bike on lowish* oil

Gonna need a rebuild bud.

In all reality chances are you’re totally fine. I would make sure it has the proper amount in it and forget about it. Remember, bikes usually end up on their side sooner or later and that doesn’t blow them up, so they’re pretty hardy as long as you’re in the ballpark.

Wouldnt worry about it.

Go back and check it in an hour. By then all the oil will have drained back down and you’ll see it in the window.

Your bike is probably fine. The pickup is at the bottom of the sump.

Also, go ahead and toss that 12mm to the back of the drawer because 13 is the new 12. Austrian bikes aren’t built to JIS standards.

I ran my 06 Honda 250f out of oil once. Put probably 40 more hours on it before selling it years later and never blew up haha. You should be dialed.

I know for sure Team Green Kawasaki would run 500cc of oil in their riders race bikes back in 07-08. Probably did for many years after as well, but I know for sure those years they did. Kawi recommended 1100cc those years in the manual.

With all that being said, with 800 in your bike, you’re fine!!

Is there a bolt on a KTM that a 12mm wrench actually fits on?

Euros and Japanese do things differently.

The drain plug is 13mm. All M8 bolts, with hex heads, are 13mm on the Austrian bikes....Throw your 12mm in the garbage.

I am sure your bike is ok. The oil pumps are easily accessible on KTM's...take the cover off and look.

So, I used to work at a motorcycle dealership that had a dyno. At one of our big open houses, we partnered with an oil company to demonstrate the importance of good oil by running an old beater bike (some '70s Honda... maybe a 400 or something,) on the dyno without ANY oil in it. We figured it would blow up within seconds. It actually held on, going full-throttle on the dyno, for about 5 full minutes. It was kind of embarrassing, actually, because we were trying to tell people to buy the expensive oil to avoid tragedy! When the thing finally started to go, it lost a lot of power and started smoking, but still kept running for at least 15 seconds before it finally locked up.

In any case, your oil pickup will probably continue to work even at very low oil levels, so you probably never even starved your engine for oil. If you did, idling is probably OK for a short while.

If you’re really worried about it you could pop off the valve cover and cam cap to inspect the journals and cams, but like others have mentioned, I wouldn’t worry.

It's fine for FS. They pick up with 250 ml of oil.

Totally fine. Some bikes will burn off 100-300ml of oil between oil changes and their owners have no clue. This was especially common in the early 4 stroke days. Things are better now and bikes don’t drink oil as much.

I’d fire your mechanic.

Engine is probably destroyed. Will need a full rebuild.
