I think the bike is at the correct level now, but he said one of the previous owners filled it until it basically started coming back out. And at one point it was so bad that it caused the bike not to run.
Ccdel is right. Kid filled the case to the BRIM, all the way to the threads on the oil fill hole. Ran the bike after that - and the PCV obviously spit a shitload of oil into the air box. Bike stopped running (fouled the plugs). Now the bike has new plugs in it, the injectors were apparently checked and they're good. The excess oil was drained and the intake was all cleaned out. The bike starts and purrs, i want to know if there could be any hidden damage - and just how possible that would be.
if the bike is running good and not making any strange noises you would be ok, the bike probably did not run that long before it stalled out.
Oil is really tough. If the crankcase was filled to the top there would be very little air to move around. It could have created crazy pressures everywhere.
Stuff could still be damaged even if its running alright. Or maybe nothing is damaged. You just don't know for sure.

If you're not leaking oil and bike is running fine then overfilling probably forced oil into the intake. All that did was more than likely stall the engine at idle rather than hydrolock it. New Spark plugs, Air filter and really cleaning the intake plenum is about all you should do - until something else comes up.
"I THINK" its at the correct now - NO. BE DAMN SURE do it yourself if you must. I never believe anything a previous owner tells me. I go home and do all the maintenance again.
For 3k i'd buy it too ; |

possible damages on car engines (new to bikes) would be the crankshaft would dip into the oil and would increase drag and stress on the engine. Short term that would decrease power and fuel efficiency, long term will take out bearings. I am aware that the tranny and engine are one unit with oil on the RR, so I am unaware if the crankshaft is designed to be submersed in the oil, I highly doubt it considering how fast the RPM's go to, I would just drain a little bit out. If you drain it into a clean container, and drain out too much just pour back in until full
*edit* on cars the transmission gears are submersed in fluid as they are not spinning nearly as fast, and have other reasons as to why it doesnt hurt the tranny, which is the same on the bike.

wow... and you came up with these "facts" a dream you had?
no gears are ever submerged in oil. they would act like impellers / oil pumps, and they do spin really fast lmao. Enough to make a milkshake out of the oil. All transmissions rely on splash lubrication, oil runs through the mesh from gear to gear splashes and drips on everything else. Crankshafts NEVER dip on the oil either. Jets aim at the pistons for cooling and that splashes on the rod bearings too. Main bearings are lubricated by internal passages. Most small motorcycle / scooter engines also have roller or ball bearings either on the rods or cranks too and those get splashed or jetted. ehhhm, i'm working on a 110cc scooter engine right now.
this is why the internet is often not the place to get your facts...

These "facts" would be a College Degree, I was stating that the Crankshaft should NOT be dipping into oil, there is a windage tray beneath the crankshaft inbetween the oil, the purpose of that is to stop the "wind" or air swirreling from the crankshaft to fill the oil with air bubbles. What I was stating is that if you overfill an engine the oil could go above the windage tray and the crankshaft could dip into the oil which would cause damage, I did not state that the crankshaft was designed to work in oil.
The transmission in a standard car is filled up about half way, there are gears in there which the fluid has submersed them at least half way, how the lubrication is done is when the vehicle moves the gears move (DURR) and splash the fluid up and lubricate around.. I didnt say anything about pump? and as Ccdel237 said the rear end is submersed, at least half way and works the same way as a transmission.
They only "gear" in a transmission that is spinning as fast as an engine is the input shaft which is attached to the clutch (should i go into how that works?) after that the gears are used to translate the engine speed into drivetrain energy to move the vehicle for certain speeds, get it?
So before you dismiss my information as some retarded bullshit, perhaps you should actually read what I wrote, and look some stuff up, good job you're an idiot
Oh I just read you are working on a 110cc scooter engine, that's cute, how about you build a few drift cars and rebuild a couple V8's then come talk to me about engines.

lol drifting... wrong person. i have been drifting and building cars since 2003. Before you even found out about Initial D kiddo. what are you in college still and think you know everything or believe everything you read on the web? nice..
when i said working on a 110cc, i meant i'm part of a team of engineer that is DESIGNING the engine, not building one. lmao. buddy, i make a living out of this

Degree bud, graduated for a while now, I've been into drifting before the initial d craze, well have fun tinkering around with a lil engine there bud, please tell me when it's complete and who is manufacturing it so I can tell everyone to avoid it as the guy building it doesn't know what he is talking about
Oh and please go ahead and tell me what of what I said is incorrect, since you're oh so knowledgable in it?
I don't mind being wrong, I learn from it, but what I stated is correct and you have ignored that you were foolish instead tried to say you do that **** for a living, blah blah blah, met too many of you guys on the Internet to see it as any bit truthful
possible damages on car engines (new to bikes) would be the crankshaft would dip into the oil and would increase drag and stress on the engine.
- the engine and crankshaft could care less about that "stress" anyone can throw that word around without understanding, but you're still wrong. The actual failure mode would be that you froth the oil into a cappuccino and the oil pump is unlikely to supply the needed lubrication and cooling for everything. Fail / leak seals from added pressure, move oil into the intake and smoke like a ***, fail the catalytic converter etc etc etc the list goes on and on.
Short term that would decrease power and fuel efficiency, long term will take out bearings.
- genius. read above how the bearings fail, not because of stress or because it takes extra power to rotate the engine. Please pick up the Heywood book for intro to ICE to learn how an engine works. It'll open your eyes to that comment of fuel efficiency too.
I am aware that the tranny and engine are one unit with oil on the RR, so I am unaware if the crankshaft is designed to be submersed in the oil
- no engine is designed to dip crankshaft or rods into oil. period.
I highly doubt it considering how fast the RPM's go to, I would just drain a little bit out. If you drain it into a clean container, and drain out too much just pour back in until full
- would you pour frothed oil back into your engine. another genius suggestion for the OP considering its $35 worth of oil and filter. NO.
*edit* on cars the transmission gears are submersed in fluid as they are not spinning nearly as fast, and have other reasons as to why it doesnt hurt the tranny, which is the same on the bike.
- we covered this in above previous posts too.
in other words EVERYTHING you said was just wrong. if this were middle school test i wouldn't even give you a point of partial credit for spelling your name correctly on the test. Real life just doesnt work that way.
So you're saying that the crankshaft smacking into oil would not damage bearings? And hat post was a quick one to let him know what the possible damages are, I didn't go into depth or anything, it's a pain on my iPhone to type so much.
I also didn't read his original post I just saw that the oil was overfilled
And yes I stated I was unaware if this engine was designed to have oil over the crank, I am new to bikes so why would I say something if I am not for certain, but I went ahead and said i highly doubt it is designed that way.
You say no engine is designed to have the crankshaft dip into oil, but I know of a few law mower engines that the crankshaft does dip into the oil as there is no oil pump.
Now tell me what's wrong with my second post?
And by submersed I didn't mean the gear is fully under fluid, but they are in fluid, perhaps submersed was the incorrect wording, I apologize that it may have confused you.
so now you want to talk about 2-stroke lawnmower engines? wrong again.
listen. take it or leave it. you're way off. i hope you are not putting your jdm drift spec chevy v8 together with this level of mediocrecy. i'm doing you a favor here. go figure things out, and not by reading someone's internet blog.
you're an idiot
NOT IT IS NOT. The rear diff.. u moron. The crown gear is barely 20-30% submerged in oil.
