The spring loaded pin on the end of your needle and seat valve is not working. They jam up and then with vibration let extra fuel into the bowl and cause flooding.

SOURCE: 2003 WR250 F - eng. won't idle down and carb starts to overflow

Hi Jwelden,
Have you checked the float level in the float chamber?
I guess you may have to reset the float pin adjustment, its allowing more gas to pass through thn required and thus the overflow!
Not bad too, when you are working on the float assembly take the opportunity to blow out the fuel line from petcock to the carburator via the seat for the float pin,any foreign particals there would stop the float pin to seal up and thus overflow.
Fit in an inline fuel filter , this will help keep out the dirt or whatever.
Hope this helps.

SOURCE: Fuel pouring out of overflow tube

Yes, it sounds EXACTLY like a stuck float. You may be able to fix it yourself depending on how accessable the offending carburetor is. Quite often you can free up a stuck float by setting up a bit of vibration. Give this a try > tap the side of the carb repeatedly using the plasitc end of a screwdriver. You are not looking to hammer the thing to death, just create minor shocks. The shocks / vibration will often free up a stuck float. Please rate this solution and let me know if all went well.

SOURCE: 89 fzr 1000 fuel pump problem

It seems likely that your fuel pump is not operating, you should hear the fuel pump priming when you turn on the ignition, if not the fuel pump is at fault, this is not uncommon and a replacement is the answer.

Strip and clean carbs, I had the same problem and that's how I fixed it. Take the carb to bits then soak all the bits in clean petrol (or prpsi believe it or not) for 1/2 an hour.

Floats are sticking in carbs and staying open which causes fuel to overflow.you can try tapping float bowls with screwdriver handle sometimes this will free up floats .If this dosen't work you have to remove and clean carbs.Good Luck

Why is gas going in my oil pan


Check your fuel tap (petcock) to be on "on" position. If you set it on "pri" it will let fuel flow without vacuum from engine. Gas flows in the carbs when bike is parked and overflows from there into the engine and down into the oil pan. If putting the fuel tap on "on" does not help then check if the tap flows fuel when engine not running. It normally should not.

Hi my honda cbr 600 fl 1991 the bike pulls great


im not sure if this model has a fuel pump but follow your fuel line and see if it does wen u find it remove black plastic cap and check the points contact breakers are in good conditon ie not worn uneven or worn out and that they open and close.check your air filter spark plugs and your carbs could have a blocked jet so get them cleaned and balanced.

96 CBR 600F3 runs for approx 10Min then stalls out.


Check the vacuum pipe from the carbs to the fuel tap, if its gat a pin hole in as you demand more fuel the vacuum loss cuts downthe fuel flow and the bike will stop!

Fuel leaking out of the crankcase


Sounds like the float is stuck in the carb.. its not really pouring out of the bottom of the cranks case.. its an overflow hose that is routed down through the motor so it will drain out under the bike.

You probably need to pull the carb and clean it, and check the float.

Bike won't start


Check compression ratio and valves clearance.The carbs leak any fuel from their o-rings.Spray through the air box with a carb cleaner spray while pressing start button but little bit at a time.Don't twist the throttle too much and always use choke until she fires up for good.

Starting problems


Check the compression. If it has low compression it will always be difficult to start. I have the same bike. It is a really good starter, comparatively to other older 'cycles I own. 1) Check the fuel level in the tank, and be sure to turn the fuel switch (left side of bike below tank and seat) to On, or even Reserve 2) In stock tuning, my bike likes full choke for cold start, in any ambient temperature, it likes to warm up with the choke on, until it starts to sputter from the rich mixture. 3) I believe this bike has vacuume tube that goes to the fuel petcock, this shuts off fuel to carbs when bike is not running. Thus if the bike has not run in a while, or the carbs drained, it will take several start attempts to get the carb float bowls filled. 4) This bike is hard to start if the battery is old or marginally charged. 5) Also pull the spark plugs, if they are brown, or black, change them. 6) check the air cleaner, if it is too dirty it will essentially act like a choke
