Gas in my Oil : Suzuki GSX-R Motorcycle Forums: Gixxer.com

Ok. So I just got a 97 GSX-R on trade and it hadn't been started in years. It wouldn't start up at first... found that the carbs had a broken choke. Replaced this and cleaned the carbs. I got it started but it smoked a bunch so I let it run for a little while and then shut it off. I was getting the oil pressure light.

I figured I should check that before letting it run too long. Went to change the oil and my oil had a bunch of gas in it. What could cause gas to end up in my oil?

I also noticed that I was getting some fuel splatter around the fuel pump when I was trying to start it. I checked the hoses and saw a broken one... I thought that was the problem. Any ideas?

stuck floats can cause fuel washdown or since u cleaned the carbs it could be be the needle and seats

correct

So what do I need to do to fix this? Would the fact that the needles were stuck in the carbs have anything to do with this? After cleaning everything seems to move how it should.

Do you think this happened before I got it or when I was trying to start it before I noticed the choke was broken? Or has it happened since I fixed it and I need to look at something else?

the needles over time can wear a ring on them where they meet the seat. then they will not stop the fuel from entering the carbs. they will over flow into the airbox then into the intake to the cylinder past the rings and into the base. but something may have also happened when you had them appart.

If the fuel is over flowing into the airbox, won't my air filter be soaked with gas?

It doesn't typically enter the airbox when a float sticks, mostly it enters the carb throat through the orifices in the bottom of the bore, like the needle jet holder (brass tube in the middle that the needle from the slide sits in) and the pilot circuit holes in the leading edge in front of the butterfly valves. Another avenue of escape in some bikes is the float bowl vent tubes, but is your case these should "Y" into one tube with a inline filter, and connect to the very front of the airbox.....if you had fuel there it would never see the filter as it would drain out prior to filter. In almost every case the fuel seeps into the carb throat and drains down the intake manifold, past the intake valves, piston rings, and into the crankcase oil.
