    Worst possible case scenario would be the oil level was high enough while running that the crankshaft splashed through it while spinning, turning the oil into slippery foam and greatly reducing the lubricating capacity of the oil. Pretty unlikely, but possible. If the bike quit and won't start again, check the simple things first. Remove the oil and refill with the proper amount. Check fuel, spark, and air. Good luck.

Open the air box,clean it from extra oil,renew the air filter if you have to and without the air box-air filter (or opened) try to start the bike while sraying with a carb cleaner spray through the air box towards the carbs.Don't spray too much.Little bit each time and do not twist the gas grip.Choke it too if you want.It may help.Of course before all that set the oil level to normal.

Gas in crankcase

Fuel from the fuel tank flows to the carburetor and then on into the engine cylinders. From there it seeps into the crank case.
It's a matter of gravity. The gas will seep until it reaches the lowest point in the engine.
There are two methods of correcting this dangerous problem.
1) When you are done using the engine you can turn it upside down, over a large container that is of sufficient size to contain all the gas and oil that will run out of the engine.
2) Turn the fuel valve to it's OFF position when you are done running the engine. This stops the fuel from seeping into the crank case from the carburetor.
(And a heads up from one who has personal, first hand experience. Be sure to OPEN the fuel shut off valve when you think you would like to start the engine.)
If you should have this happen again DO NOT try to start the engine!
(That's one of the reasons The Da always said, "Did you check the oil before you started that engine?")
Dump out all of the oil that has been contaminated with fuel and replace it with fresh oil.

I want to change the oil and i want to know how much the bike takes oil i have the yzf r1 1998.thanks

just put in three quarts keep bike level start bike for a minute turn off then when its still up right fill it only to 3/4 of the way up the sight glass or stick this will help to keep from over filling. If you over fill you case the crank splashes the oil around and stirs it up and make bubbles or air particles and this could damage your main bearing so its always better to under fill than over fill.please rate my expertise i like to hear feedback.

It should be the small plug up near the steering head with the dip stick, you need a small funnel, use only motorcycle oil, car oil can cause clutch slip.They hold about 1.1 litres . you then need to start it for a couple of minutes then check with the dip stick

How much oil does it take?

2 stroke or engine oil?? if its 2 stroke then all you need to do is fill the compartment but leave about an inch at the top and try and keep it at that level,
but if its engine oil then i wouldnt put to much in because if you do there will b to much compression inside the chamber wich would cause alot of strain on the cogs ie. (severly damaged) so wen you have the dipstick out have a look down the hole and you should b able to see one of the gogs if you can feel the cog and if it is lubricated then your ok so fill about half way up. another way to check this oil is.. wen your bike is upright the spyglass should be filled with oil and wen you have the bike on the side stand the oil should no longer b there thats the ideal way but obviously if theres oil there whilst on the side stand then there is to much in there

EVERY motorcycle I've owned had .."cast" into the case near the oil fill the fill this case
1.8 qt. or for our metric buddies 1.7 litres ... MAKE SURE you use oil intended for motorcycles with wet clutch new "auto" oil has additives that make them too slippery for wet clutches

On the oil filler port is a number with CC after it. This is the crankcase capacity in cc. There are 946cc in one US quart. Do not neglect to fill the filter with oil (but do not overfill) before installing it, and do not consider that amount when filling the crankcase.

Hope this helps,
