1986 vf500 fuel in oil!

I have a 1986 VF500 Interceptor and removed the gas tank to tighten a clamp onto the fuel valve.
PLEASE LOOK AT THE PICS OF THE CUSTOM FUEL LINE SETUP THE GUY BEFORE ME HAD: http://s282.photobucket.com/albums/kk241/chsherbie/vf500 fuel line/
There is no fuel filter or anything in the fuel line.
When I removed the tank one of the hoses leading from the fuel valve to the engine got disconnected and I did not see it. I tried starting the bike and gas went all over the place and Im assuming into the airbox. The clear airbox drain hose was spewing out gasoline. Anyways I reconnected the hose where it had fallen off. I smelt the oil and it reaked of fuel. I drained the oil pan and 10 quarts of fuel/oil came out. I tried turning the bike over with all the oil out of the bike and no oil filter on and gasoline is coming out of where the oil filter screws on. I only attempted this not out of stupidity but to see if the gas would keep going into the oil after I changed it. I dont have any experience with bike engines but am an engineer and am fairly mechanically inclined with a nice craftsman tool set, Honda service manual and air compressor with some pneumatic equipment for that. Can someone tell me what the happened to the bike?

 

Has the bike been sitting? The fuel in your airbox was probably pumped up there through your crankcase breather hose. If you have floats that leak, the gas will flow into your cylinders then down into your crankcase and overfill it. Have you been having fuel related issues with it recently?

 

Sounds like what happened to my '82 Yamaha when the float needles did not seat properly. Engine was flooded with gasoline as a result.

Not the best way to do it, but I bet the inside of your motor is pretty clean now!!!:smile:

 

Yes, I would be looking at the float needle valve and seats. If need replacing, better have much cash. Try cleaning. Check float level. Don't forget to put oil back in your bike. Just think, the inside of your engine is clean.

 

Another update to prior questions everyone. I purchased the bike at the beginning of the summer and didnt have any problems with it. Sometimes the starter would just click when i tried starting the bike instead of attempting to turn the engine over. By pressing the start button in some short bursts and turning the ignition on and off a few times the bike would eventually start right up fine. Im not sure why that was happening. I believed there was a small amount of gas leaking from the fuel valve right underneath the tank so I put a better clamp on there to stop the smell. After putting the clamp on the whole story starts where gas went into the airbox etc.
If I have not worked on bike engines before but have some mechanical ability and tools along with the Honda Service Manual do you think it is possible to fix this myself. Another thing, how much money do you think it would cost on average for me to get this looked at and fixed at a local bike shop?:unsure:

bump to the top

 

The link to your pictures in your second to last post does not work, it only brings you to the main page of the site.

I checked out the photos on the first link, and they are not really conclusive, since most of them show very little of the hoses (and where they originate and terminate). Am I correct to assume that the long hose in the first picture is the fuel feed line? If so, this line should connect to the plastic lines that connect all of the carbs together. There technically should be some sort of inline filter on this hose.

I would have to say that the starter issue is most likely a "dead spot" in the starter windings. A lot of cars have this issue as well, most likely causing your problem. Either that or a dying battery.

That problem, BTW, is unrelated to the fuel in your crankcase. Your application of a clamp on the hose probably is unrelated as well. I think that you need to have the floats and their needle valves/seats checked out.

You are in a tight spot, though, because a lot of Honda shops might turn you away because of the age of the bike.

 

thanks a lot for the advice. looks like ill be ripping the carbs apart!
