Carb pooring out gas

Not sure what is making this happen the bikes been running great for awhile. But I hit a bump a few days ago. It seemed to be doing fine but got home and noticed my gas tank was totally empty and the engine and chain was covered in oil. Filled it up and seen the gas is pooring out the carb nearly as fast as I poor it in. I've taken the carb off cleaned it then it ran well for about 2 blocks then sputtered out. Thing was pooring out gas again. Adjusted the fuel flow from the tank and on the carb in to try and compensate but there is no in between it seems. *Opened to 1/2 or full it will spew out gas. I've got a way to get it to run for a few minutes at a time by starting the engine with the gas totaly off then opening it once its moving. It won't leak and flood out for about 2-3 blocks. Then it starts choking and sputters out pooring gas all over.

After looking threw the forums for awhile I wasn't able to find any post with this problem so I figured I would toss up a thread and ask if anyone has any idea on what might fix it. I know there are some little metal risers in the carb I could bend that might fix the leak but I want to ask and make sure before I do anything like that.

Your carb float is probably out of adjustment or you got some trash in your needle and seat valve. Do you have a fuel filter between you tank and carb?????????

yup, probably stuck float. or broken float. or adjusted wrong float.

and with the gas off and it still leaks, your carb petcock might be messed up. what about the one on the tank? if you turn that off, does it still leak?

and one more tip. flashy pictures are kinda annoying. trying to focus on your bike to check obvious problems is no fun when the pics keep changing...

In fact some floats have cracked and will fill up with gas. That will do it also................

look like you guys got it covered, wrong float adjustment, sticking float needle or full of trash,or the float that has turned into the Titanic.

Yeah, I've got a fuel filter in the line. I'll try taking it apart here soon and see if there is a crack in the float or anything obstructing it.

On another note. The air filter is a very tight fit on this bikes frame "that's why its just a filter and 2 screws in the pic". Could someone post where to get a shorter intake?

I make an off set intake for the carbs that don't have room to fit with out hitting the frame.

I have extended intakes and cut them short aswell to fit depending on what people want. The best thing to do is make one , make friends with someone who has a welder its a 2 min fix.

I will have to adress a frame interferance problem shortly. I am all set except the throttle cable housing will hit the horizontal frame member. May I see a couple pics of off setting the carb. Ultimately that will be my solution either by a short length of hose or fabricating an angled intake manifold. I don't want to re-invent the wheel if it has been solved and done befor. Thanks. A couple pics will help me out allot.

Her you go I paint them after I make them so they may be hard to see, also had I have known I was going to send pics out I would have taken close _ups. Sorry. These are a couple of early attemps, I have made them better and I find it works and looks better on the right side and behid the seat, but these were the only 2 I had saved. Sorry, hope they give you an idea.
Thanks
