Chain wobble

Working on a zrx swing arm swap and when I run the rear wheel there’s a slight wobble in my chain. With the left and right essentrics set on the same marks makeing sure the rear wheel is square I’m not sure what could be causing the chain not to run in a straight line. Any advice?

Bent rear sprocket is most likely or out of true carrier if it's had to be machined for chain alignment.

yikes. i did just have a machine shop remove some a few 16th from the sprocket side on my carrier. what the hell do i do now? i will see if i have an old sprocket to see if that help, but if not..

Bring your sprocket hub to an professional machine shop.
The sprocket hub has to be trued with a dial indicator on the lathe
for a wobble free turn around (axial/radial on the bearing side) before machining.

i went out tonight and picked up a dial indicator. with everything mounted in the swing arm

my wheel has .002 of deflection
and my sprocket has .008-.009 wobble
and when i put it on a surface of the carrier that was machined im close to .010 of and inch deflection. This is what i have to be seeing in my chain.
