chainline issueee

probably the chainring being bent (if you are having a rhythmic side to side movement of the chain).
if the chain is tight and slack, when the drivetrain is moving then it means the chainring is not centered on the crank.

yes my bike is a conversion, and when the bike is spinning the chain moves out of its place, looks wavy. the top and bottom chain isnt parallel with each other when spinning.

Even if its not the problem, check your chainring bolts.
