I had an accident on the track and must admit my insane stupidity.. :thewife:

the accident broke the left engine cover and the bike lost oil. i had it fixed with the mechanic at the track. well, i thought that he also refueled the oil but he did not. (it was in italy so it was difficult to communicate) unfortunately i had 2 slow stints before it came to my mind to check oil level. max 30-40 kilometers. i am not exactly sure on how much i needed to refill but it was about 1-1,5 liters. afaik the F41000r has 3,5 litres in total so that means my bike ran on 2 litres for 30-50 kilometere track very moderate still i travelled to another track after the accident, which was new to me and i had to learn to now it etc. , but still track use.

at no point the oil pressure lamp went on. there were no strange noises and therer are none now. the coolant temperature was as before. the engine runs as before..for the moment at least

after that i did one more day of real track riding with no problems.

apart from my brutal stupidity, do you think my engine might have long term damage or anything. my gues is if oil pressure is still ok, it should be fine?

No it should be fine dumb arse :) I'm making a joke for those non humorous members.:naughty:
If oil light did not come on and bikes still running okay then you will be fine.
Change oil now and ride smart. :):thewife::f4:

I am a dumb and lazy ass, no doubt about that.

its just, you know, obviously i am worried, since the bike ran on 2 liters or a bit less maybe. maybe only 1,5 litres, i do not now exactly how much i had to refill... lets take 1,5 litres inside the engine as worst case.

i guess on a standard car engine this is no problem but on a high performance engine like the F4 i am worried if i have to expect damage of any kind after further 1000-5000km due to that.

Did you do any wheelies?

It is a pressure fed system. As long as there was oil high enough in the sump for the pump to pick it up then you are fine. no oil light means you never lost pressure.

For sure, the reduced oil got hot and well used, but thats OK. Serious racers used to run oil levels as low as possible to reduce windage and pumping losses in the engine. That was a while back when engines were not so advanced as today.

You're fine. Sleep easy.

obviously i cannot 100% say that the lamp did not go on while riding for a few moments , since i cannot always look dont there in the middle of the action. but i would the lamp to stay on or is this a on/off thing?

It's an on/off thing based on a grounding signal from the pressure sensor......but seriously, if you damaged the engine it would be letting you know by now, you've ridden it a fair amount after just a few short runs before refilling and then changing the oil.

I certainly wouldn't start tearing the engine apart just to look.

It will be fine...just as the others have said.
Were you going to have a problem, it would have manifest itself by now.

You`ll find out down the road, it's probably ok. But I wouldn`t buy a bike knowing that history and neither would anyone else.

Bear in mind that at start up your cams are waiting a moment for oil feed.
The other end of the spectrum is overfill.

If you overfill then the oil gets whipped into an aerated froth.
So your vitals are being fed less oil and more air.
Like the boys have said with 2 L of oil and positive pressure you have nothing to worry about.
I'd rather have your situation than overfill

i lost the front in a left corner in franciacorta. the bike slided in the gravel, .

the engine cover left was through, it was actually a small hole. i got very lucky that nothing went inside the engine.
