My moped is making really loud air sounds randomly while I'm riding. I have a Yamaha razz with a dd50 motor. It has a pg long, 72 polini, 28 Oko, 7-1 gears. The sounds when I'm riding goes like this..
Bapppp, bapppp, psst, psst, bappppp, psst, bappppp, psst, psst
The bapp sound is my motor and the psst is the air sound

Re: Loud random air sound while riding
Crack or leak in intake manifold? Is it running differently now that you have the air sound?

Drain all gas from the tank, fill back up with fresh. Replace your spark and gap to .025", check head bolts loose/ maybe you have a bad gasket. Take a look around the engine for signs of fresh oily stuff leaking.
