Hello, sounds like you need to set floats in carb, if you have already done that, buy new floats, sounds like one or more of your floats are bad, when you cleaned carbs, did you check and see if any gas was inside the floats, sometimes they will get a pinhole in them, then they will fill with a little gas, and they wont turn gas off, because they cant float in the gas, the carbs are letting gas run through intake down into motor, always turn gas off when not riding your bike that might help a little,

Why won't it idle without choke?


Fuel supply problem somewhere. How is the float adjustment and the float valve? I'd guess the level adjustment is too low.

I have a 92 vulcan 500, starting coupla days ago it leaks gas even when the bike is off. the air filter was soaked in gas when i pulled it out. i cleaned it but the gas seems to come from the carb directly...


This sounds like a carb overflowing this normaly occures when the float valve sticks, you will have to remove the bottom of the offending carb, remove and clean the float valve assembly inc seating

Petrol pissing out through air box bike not starting


hi, you dont say what bike this is, however the main reason for this would be at least 1 float valve not closeing, has the bike stood for a while, classic symptom, reason for not starting would be overfueling, normaly you will find a drain screw on each carb with a pipe for fuel to overflow, this would then be oviouse which carb is giving the problem as the fuel flows out of the problem carb overflow, your overflow tubes which are located inside the float chamber may be blocked, i would think that in this case a strip down of the carbs to check and clean as ness would be in order, in the same way the fuel will run out through the airbox it will also run into the engine, causing it not to run

Fuel leaking from carb from over flow tube


Sounds like the float is sticking, you can get card cleaner from motor shops that you spray inro the airbox (remove filter first)while running the engine, otherwise you will need to remove and clean the carb. Examine idle and main mixture adjustment screws and O-Rings for cracks and damage. Check inlet needle and seat for condition and proper installation. For detail about carbs check here-->

Fuel leaking from carb vent tube on newly cleaned carburetor


that would be either the float set to high or the needle and seat is missing an o-ring while you had it apart. Should look at getting a carb kit there only approx. 23 bucks and it would save you a lot of grief in the long run.

Carbs problem


Remove the fuel line from the carb. Turn the gas on > got flow? If not then clean the fuel line and petcock filter if it has one. Install an in-line fuel filter or replace the present one. Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Use compressed air to assist in cleaning. Is the float needle stuck closed? Be certain the vent tube and vent port are clear.

Fuel in airbox


If your particular model has carbs instead of fuel injection, have the shop clean, balance and syncronize the carbs. Done properly, this will fix the problem.

Fuel leak


Wait... fuel is pouring out of the crankcase breather? Are you sure it's not the carb overflow tube? The crankcase breather should be going back into your airbox or through some kind of filter. If gas is coming out of there DO NOT START YOUR BIKE. It means that gas has gone from the tank through the carbs into the cylinder and is now in your oil. Thinned out oil is the devil for bikes. Sounds like you'll need to clean the carbs and set the float bowl height and maybe rebuild the petcock. Check to see if any fuel is coming out when the petcock is turned off. If it only has on pri and reserve then check for gas in the vaccum tube.,,
