I have a 1993 Honda CBR 900 RR, I was riding the other day and suddenly a heavy cloud of gasoline vapors burning off of the exhaust came up and I thought the bike caught on fire, so I pulled over immediately and got off and got away from it. I then noticed that it was leaking fuel. After I managed to get it home I took the tank and airbox off and cranked it up to see where it leaked. Well, it wasn't leaking cause nothing was broken, it was actually spitting the fuel out of this vent tubeon the carburetor. Here's a couple pics of the vent tube.

Any advice would help. Thanks alot in advance.

Watch how the carbs have the dry fuel spots.

Watch how the 2nd cyl from R to L has fuel, well this is the cyl that's flooding.

I hope this is enough, but if you need video of the event occurring just let me know. Anything would help.

 

that vent tube should have a hose that comes off of it and hooks into the airbox. there is alittle black box about 3 inches square that bolts on the bottom of the airbox and in goes in to it.

 

hey i looked at the pic again and noticed what tube you are talking about. there is one on each side. they should have a tube that goes between both of them and then goes back up to the gas tank.

 

Not too sure about the last reply.I have a 93 900rr and the only tubes going to the tank are the breather tube, overflow tube, and fuel line. They are all in the same area over the fuel filter as you probably already know. I will take a look at the honda manual in the morning and try to help out if now one else has the answer by then.

 

Thanks guys. I really appreciate the effort. I guess ya'll understand what it's like not to be able to ride. Thanks once again and in advance.

 

I still need help guys. I can't figure it out, I've looked at most things and don't know where to look now. I would take it to the shop but I still feel it should be something small cause it was so suddenlike from one second to the other. Well, any help would be appreciated.

 

im gonna have my bike apart here in the next day or so i will try to take some pics of my carbs and get them on here so you can look and see if anything is different or if maybe something fell off.

 

sounds like a stuck float in the carburator. I had this happen to an F2 once turns out thats what it was just my .02 hope it helps

 

Like TBone said, sounds like a stuck float.

 

So how would a stuck float free up?(if that were the cause)
