Petrol coming out my overflow - 2001 Yamaha SR 125

No, the overflow tube should dump the fuel out the bottom of the bike.

Possible solutions (?): 1: Don't over fill the tank. 2: Check for corrosion in the tank overflow tube.

They are fuel overflow hoses, and just hang down under the engine. If they are not vacume or fuel lines, then they must be the overflow pipes, one from each carby.

Yes, the float or the float needle is sticking in an open position. The only other possibility is a float that has a pinhole in it and has filled with petrol and will no longer float as it should.

Your float is stuck and allowing fuel to overflow. If the float, floats it checks off the fuel exactly like the tank on your toilet.

sounds like the float is stuck,inside the carb.try tapping on it with something or hold the front brake and bounce the front end,if that fixes it ,its only temparary,need new carb ki ,installed

Most likely comes from the carburetor's overflow tube.Start looking in there to rule out the possibility of overflowing.If it is so you need carbs cleaning and adjusting.

Hi!
Your description although very brief appears to relate to carburretor as overflow will only occur due to sticking float valve.
A clean up of internals required, attention carefully to float valve.
Good luck!
Oh if you respond positively with Fixya button it will be a great help?

Hi ...... Sounds like float levels are set too high or debris in float chamber. Switch petrol off from/at tank and drain fuel from float bowls, if you use the cap off a paint can etc you can catch it and look at it to see if any water or debris present. Retighten drain screws, switch petrol back on and see if it still overflows.

one's a breather and one is petrol overflow (i think?) they will both go down to near the left foot and come out at the end with another pipe...the coolant overflow.
