dropped bike

i dropped my panigale v4 yesterday on its right side, the bike sat on its side for about a minute or so before it got picked up. oil was leaking out of right side from up high on the engine it seems. there is no damage to the engine so where could that oil be coming from?. it no longer leaks since its upright, just want to know where it came from so i can clean it up. thank you sirs

sure it wasnt gas?

it was definitely oil

Honestly I can't think of where it would be coming from but I'd pull the fairings off and have a look.

All street engines will have some sort of PCV system that takes fumes from the crankcase and sends the fumes through the intake while sending oil mist back into crankcase. It'll do it through the airbox. When upright gravity keeps things in. On its side it'll drain wherever a gap is in airbox.

The air box has an o-ring seal. Where the fuel line enters it it’s not the best seal, but it is on the right side.

It’s definitely a crappy seal looks like some shredded rubber string and they didn’t even put mine on correctly from the factory

do i need to get in there and wipe it out or let it be? can i get in there thru the air filter opening?

I'd do more to determine where it came from.

I agree you have to find it first

Yeah, I would pull the plastics and see where the oil came from. Here is a pic of the "sealed" airbox on my Ducati XDiavel. Your oil could have made its way through the crankcase breather tube into the airbox and then leaked out. The oil in my pic was from overfilling the oil during an oil change (note: don't measure oil level in a Panigale motor the next day without running the motor as the oil level will actually decrease in the bubble over time), which caused oil to blow out the "sealed" airbox. I realize my situation was different than yours, but the concept is similar.

Also, note that XDiavels don't like wheelies (i.e., sucks oil into the airbox).

Did you mean increase over time? A Panigale has to sit upright for two hours to take a measurement of the oil in the sight glass.

i looked in the airbox with a camera and found that the oil came out the breather tube just like yours did. i found out also that my sprint air filter doesnt stop pollen very well lol. it wasnt bad but it was still there

That's good that you found the oil leak. Which Sprint filter model do you have? I have the P08 in my XDiavel and the P08F1-85 in my V2. I have not noticed any pollen yet but we do have snow on the ground, LOL.

I don't want to take this thread in a different direction, but I will answer the question in case someone else finds this in the future.

My 2021 Panigale V2 manual disagrees (as do my findings) that you must sit the bike upright for two hours to take a measurement. Maybe your bike is different. My V2 manual says to get the oil hot (ride for 30 min or run bike until fan starts/stops twice). It says you can leave the bike on the side stand while warming up. You wait for 10/15 minutes and then check the oil.



Here is a pic of my V2 oil after sitting overnight (shows mid-level)


Here is a pic of my V2 oil after sitting 10/15 minutes after a long ride (shows max-level)


If I were to top off the oil based on the mid-level reading after letting the bike sit for a long time (hours or overnight) then the oil will be overfilled. Letting the bike sit for a long time makes the oil level in the bubble decrease, not increase as one might expect. At least that is what I observed for my XDiavel (Panigale 1198-based motor) and my 2021 Panigale V2. Your bike might be different.

That’s different from the V4 manual, which says that the engine must be off for two hours for all of the oil to reach the sump. Likely why dealers keep over filling them.

Yeah, that doesn't surprise me. I have a spreadsheet with the process for checking the freaking oil level for all my motorcycles, LOL. Warm from some, hot for others, and COLD for the Ducati cafe racer. Some have to sit for longer than others. Crazy, but it makes sense based on the location and the way the oil has to reach the sight glass. My XDiavel is the most sensitive to letting it sit too long. It shows really low levels the longer it sits. Weighing the oil for changes is an easy way to get it right, but that doesn't cover topping off due to burning or inhaling (wheelies) oil.

Hey guys, just jumping in here. If the bike sits overnight (cold) vs. 10/15 minutes after a warmup/ride (hot):
Hot oil is expanded to max volume, cool oil is contracted to minimum volume.

Does flat and straight position mean upright no side stand?
The V4 manual suggests the max line should be marked if the bike sat for 2 hours. I assume 2 hours means “at least“ 2 hours, as in after a ride?
Let it sit two hours for the oil to reach the sump. -OR- sat overnight or forever after the last ride and in this case just stand the bike up and read the sight glass?

My point is if the bike is cold and you read high on the sight glass, when you cool off again it should read the same or lower if oil was “consumed”.
If the oil was warm, semi warm, whatever when you read the sight glass, the oil was expanded from the rise in temperature and will give false level readings just based on it’s current state of property.

My logical thought would be to read it “cold” to get the precise level, as in at least 2 hours after a ride or engine running at all causing the oil to circulate through the engine, or the next day after sitting overnight, then stand the bike up straight and look at sight glass. This would be your best sump level reading is my thoughts.

So keeping the sight glass at the max line is the recommendation. Is that at the cold read, or the semi warm read, or the “hot” read. Side stand or straight up ?

If it is filled to max level cold, it will raise above max level when it expands from the temperature rise, then back to max level cold when it settles down.

Or

Its filled to max at warm-hot conditions meaning max is THE MAX for the oil sump level to go. Can only go down from there as it cools.

The V4 motor is a dry-sump design. The warm/cold aspect has nothing to do with the oil level. When the motor is running, very little of the oil remains in the sump, so the oil level will be low. Once it is shut off, it takes time for the oil to settle back down in the sump.

This is why people overfill. If you warm the bike up, the oil level will look low because it's actually up in the motor still. You fill it to the correct line, then the old oil settles and you realize it is way overfilled.

OR

People warm the bike up prior to draining (like with most bikes) and only some drains out. They seal it back up, fill to the correct level, only for a good chunk of the old oil still sitting up in the bike and leading to an overfilled condition only noticable once it all drains back down.

Oil level is read in the cool condition, bike upright. The bike is considered cool after 2 hours. There won't be a significant difference in oil level between 2 hours and overnight.
