My gas tank has funny sound
Is this normal. My fuel tank makes funny sound every now and then. Weather is not even warm yet about 15 deg celcius. I know when ghe bike is under the sun it makes funny sound but mine makes sound very often even not under the sun

Or its the sound of the last gasp of a dying hamster. |

Yeah, I usually just pop the gas lid open while stopped and it goes away for a while.

Via a system of ports and silicone disc valves housed within the fuel cap ...your tank is actually able to "breathe".
Fuel expands when when hot..under pressure...the valves allow the tank to "exhale" As fuel depletes...the tank "inhales" to prevent vacuum induced fuel starvation. The sounds you're hearing is pressure relief through the tiny flapper valves which reverberate and make audible sounds. The valves can clog....thus creating a vacuum inside the tank...no flow to carbs...mimicking out of gas. Think finger over the end of a straw. Opening the fuel cap temporarily eliminates either pressure or vacuum. The flapper valves can be safely removed if clogging creates stalling, which it can. A search should reveal posts documenting the procedure
