Motorcycle Repair: Fuel in the oil, kawasaki ninja, float bowl

Question
I own a 93 ZZR600 Kawasaki Ninja. My problem is that there is ALOT of fuel leaking into the oil. So much so that it filled up the oil Reservoir. Needless to say, but the bike wont start. What could be the problem and what can I do to fix it? Also do I have to take apart the engine to get all the gas out so it wont burn up the piston sleeves?

Thank you for your valuable time.

Answer
I usually only answer questions on Harleys, but I might be able to help. the only place you are going to get gas from into the oil is through the carb. Sounds like you have a stuck float bowl.
You dont need to take the motor apart. Drain the oil and change the filter and replace the oil. Spray some WD40 into the cylinders and get the bike running. Let it run for a couple of minutes and then change the oil and filter again. Start the bike and let it run until it get good and warm. Change the oil and filter again. Now go for a ride for around 20 miles. CHange the oil one more time and you should be ok.
Good luck and happy riding
