Lithium King QS138 Rear Motor Mount

Got a question about the Lithium King motor mount for the QS138. I didn't install this but is the rear of the motormount (the part that goes through the swingarm axle) suppose to just float on the spacer? From what I gather there is suppose to be a spacer that goes over the axle, I guess to give the swingarm something to grab onto. Then the mount is suppose to go other that? I'm having a problem where the motor is crooked and when I reverse the motor it is binding big time. I think the only reason the chain is lined up corrected is the sprocket floats enough to align with the chain. The bracket is bent also, I'm guessing the torque of the motor might have bent it. Is there suppose to be spacer or shims to help align the rear of the motor or is it really suppose to just float there? Trying to get this motor rock solid and aligned properly.

Notice in the picture the right mount looks all tweaked.

I think I figured out the problem the front mount was misaligned a whole lot. They didn't shim it or put the correct size spacers. When i removed the nut I saw the subrame bracket just bend outward they were squeezed in so much. I think I'll shim the front mount properly then the back should line up. So many shady stuffs I've found in this project bike =/

Nothing fits right on this bike also. They drilled out or elongated a lot of the holes and use smaller bolts to line stuff up. I question how strong everything that's bolted together. I will put bigger bolts to fill the holes and make sure everything lines up properly instead of stretching to stuff to fit o_O'

in case that helps:
for the lithium King mounts I used one long pipe across the whole visible part of Swingarm Bolt then put the LK Mounts on it and adjusted the motor to the correct sprocket position.
Then took the measurements of the 3 Spaces before middle and after the LK Mounts and then cut to size some bigger pipe that goes over the Pipe that holds the LK Mounts so it makes the LK Mounts impossible to move right and left anymore.
Small long Pipe:

3 Bits of Lager Pipes that go over the first long one:

just looking in my Amazone history xD it was a:
Aluminium Pipe: 17mm inner 20mm outer Diameter
Aluminium Pipe: 21mm inner 25mm outer Diameter
Due to manufactoring tolerances ther was just a tiny tiny bit of force needed to move the 21 inner tubes on the 20mm outer tubes so they sit quiet snug with no movement up down.

The Lithium-king mounts are not sold as a plug and play. I have used them numerous times and they all are required to be adjusted to fit. Alignment of the sprocket to sprocket is most important. Once that is aligned, the spacers are needed to make it all solid. Then I would recommend to weld the mounts to the swing arm bolt spacer, in the end these are universal mount , and need customization. On some bikes you even need to offset the front mount to the left over the top of the original frame mount. Look at this 2023 Honda mount.
