It could be condensation from hot exhaust gases on the cool exhaust pipe.
how to quiet a exhaust on a pocket bike without buying a new exhaust?
its when you have either mixed your oil too rich or you need to ride more on the pipe.
A slip on exhaust will give a dirt bike more power. A full exhaust setup will give you even more power than a slip on.
metal - duhhh.....
go to pocketbikeparts.com and go to parts and choose your style pocket bike.
Put a different muffler on.

They are like slip on exhaust. They allow the bike to emit exhaust easier. They also give your bike a new sound. If they are racing baffles they usually make your bike sound louder & meaner. They do add a few HP usually depending on which baffles you get.
if your talking about white smoke coming out of your exhaust it is burning off excess oil. this can be if you have over filled your engine or if the bike has been sat for a while. it should burn off eventually
Put a potatoe in the exhaust pipe
no
Opens and closes the intake and exhaust valves.
