Sounds like a stuck float not stopping the in-flow of gas. Try giving the carb a whack with the handle of a screwdriver or something. You can use a hammer if you use your noodle and don't beat the carb to death with it. Plastic handled screwdrivers are less likely to break of chunks of carb. You may need to remove the floatbowl and check the float needle if the tool violence fails.

What should I check next? Not getting any error codes, replaced the CKP, MAP, IAC, TP, & ET Sensors. Not sure what I should try next, any suggestions would be appreciated.


Hi Bruce, might have gotten some bad gas. Drain the tank, clean the fuel filter, check the bottom of tank for rust, dirt, water ect. Then ckeck fuel pump pressure, refill tank with a gallon of fresh gas from a different source and take it for a ride. good luck

1981 yamaha 650 what position should the petcok b in? pri res oo on


Fuel petcock position depends entirely on what you're doing with your bike at the time.

In normal use, the fuel petcock should be set to the "on" position and left there. In that position, gasoline will be drawn from the tank only when the engine is running and generating vacuum. This prevents overfilling the carbs when the bike sits.

When you're riding the bike and it starts to sputter, it's time to move the petcock to the "reserve" position so that you can use the last few drops in the tank (on a 650 special, this was either .3 or .5 gallons--can't remember which off the top of my head) to nurse your bike to a gas station. Once you've filled the tank, move the petcock back to "on." The bike will still run fine if you keep the petcock in the reserve position, but when it starts to run low on gas--well, you won't have that emergency reserve to get yourself to the gas station.

If you've managed to run the bike out of gas completely, or if you are getting the bike ready for service after having drained the carbs for the winter, you'll need to move the petcock to the "prime" position for a few minutes. This by-passes the vacuum line cutoff mechanism and lets gasoline flow until the carb floats shut off the fuel valve (this is also how all older motorcycle fuel petcocks operated). A sticky float or poorly sealing float valve in the carb can, however, cause far too much gasoline to drain into the carbs (and into the crankcase, if you're particularly unlucky), which is why you should not leave the petcock in the prime position for an extended period of time.

Some Yamaha XS650 motorcycles (can't tell if that's the model you have) have a tank with two fuel petcocks, one on each side, to fuel each carb. If you have a tank with this setup, be aware that setting one fuel petcock to "prime" will affect both cylinders, as there's a crossover tube to equalize fuel levels between the carbs. Also, for reasons I could never figure out, on one XS650 I owned, moving either petcock to "prime" permitted fuel to flow on a gravity feed out of both petcocks simultaneously. I could never figure out exactly why it was doing that.

Fuel over flows thru overflow tubes only when motor is running. motor off ignition on it stops.


Hello
Your gas tank petcock is diaphram operated.
there is a vacuum line coming off the intake, that goes straightb to the petcock.
when you turn the motor over a vacuum is created, pulling the petcock diaphram back and allowing fuel to flow to your carburetor. when you turn the motor off the vaumm is gone and the spring behind the diaphram pushes it closed and stops the fuel flow to the carbs.

Now the reason the carbs are overflowing is because the floats valves are not closing, in other words the floats are sticking.
Usually a good carb clean will cure the problem, especially for that year.
the older ones usually require new float valves/seats that are usually found in a good carb rebuild kit. You shouldn't need one.

If your really broke try tapping on the bowls of the carburetor lightly, while the engine is running, sometimes the vibration will vibrate a particle loose that may be holding open the float valve.
if it works then the fuel should stop overflowing while running.

if you know how to work on it, try this, with the engine off.
open the carburetor drain screws so that fuel will run out the carb. drain. flush out the carb.
get a container to catch the gasoline.
while fuel is flowing tap the carb bowls a few times then closed the drain screws.
clean up any spilled gasoline .
start your bike.see if they stop leaking and the floats are closing.
if it still leaks, you'll need the cleaning.

Happy Riding
Best Regards

Regarding the fuel stopcock of yamaha chappy, it has three settings: on, reserve and PRI, what is the neaning of PRI?, thanks...


You have a vacuum operated petcock....so that when engine starts and draws vacuum...a diaphragm lifts in the petcock to supply fuel to carb. When the engine shuts off...vacuum is lost and the petcock closes.
If you run the tank empty....in order to get fuel into the carb and get the bike started initially....you can open the petcock without engine vacuum by rotating petcock to the PRIME position. Once started return the petcock to the ON position. If you leave it on prime....with engine off...fuel may leak into carb and run into engine and contaminate crankcase oil with fuel.

most likely the float has become stuck in the closed position.
Check to make sure fuel is still running out of the petcock
Open the drain on the Carb (should be located near the bottom) turn on the petcock. Fuel should flow from the drain freely. If not then the float needle is either jammed or some thing else is inside the carb stopping fuel from flowing into the bowl.

Vaccum lines from carb, where do they go?


Check the fuel petcock to see if there's a similar-sized fitting.

Most carbureted motorcycles use vacuum lines for one thing only: To apply vacuum to the fuel petcock so it'll turn the fuel supply on ONLY when there is vacuum being applied.

Though the same bikes also typically have positions on them that override the vacuum safety system.

"Vacuum safety system"?

Yes.

Unlike a car, most bikes carry their fuel ABOVE the carb, and instead of a fuel pump, use gravity to feed the carbs. If you've got a petcock that's always open, only the float needles in the carbs hold back the fuel flow, and these are prone to being held at least partially open. The tiniest speck of debris can do it.

And the results can range from annoying to catastrophic.

If the fuel is flowing into a carb while the bike is parked, you can fill a cylinder and, when you hit the electric starter with good battery power, you can bend a connecting rod since liquids cannot be compressed. The piston will slam into the incompressible liquid and if the starter's stout enough, there goes a rod.

Or if the fuel leaks into a cylinder whose exhaust valve is open at the time, the bike will start but sometimes you're left wondering what that loud bang was and why are you feeling so warm and where on earth did that muffler go?

You should get this taken care of quickly because if I'm correct about this line, not only are you having to use manual override positions on the petcock (not a biggie -- the vacuum part is a frequent failure point -- just turn the petcock off when you park it), you have a vacuum leak which can result in at least poor running and though the leak is quite small, there's the possibility of running too lean and burning a hole through a piston, which kinda sucks.

Well there only one way the fuel can get into the crankcase and that's from the fuel tank. The petcock must be draining and the float needles are not stopping the fuel flow. Do you have a prime position on the petcock? If so do not run the bike in the position. Try topping the tank off with gas and letting it sit for a while and see is the gas has gone down and then check the crankcase and see if there's fuel in it again. i still say its got to be your petcock.
