Want this question answered?
The gas making the popping noise is hydrogen.
If by "popping noise" you mean backfire, it could be crossed ignition wires, or some sort of misfire.
Could be one of a number of things, as it could be in any vehicle.
Rice Krispies IHTH :)
Maybe a stone stuck in the tire tread.
Just grease the fittings... It makes all the difference
i have a jonway 49 cc scooter. it has been bored out but i dont know how much. but whenever i go down hill or reach 60km/hr it makes a popping noise like is is backfireing
could be a contant velocity joint
Replace the speakers. Adjust the Fade/Balance and listen to find which speaker is popping. The popping noise is most likely from a broken cone in the speaker
you probably need a cv joint
You can test the presence of hydrogen gas by using a burning splint and if the gas makes a "popping" noise
try replacing your coolant temp/sensor $5.00
