I am looking for the removal process of an aq105.
I was looking to replace with an aq120a

will the two two
motors swap?
Thanks for the help.

Short answer....... no!

The 105 is a push rod engine..... the 125 is an OHC engine.
The rear flange for the flywheel cover is very different..... not to mention several other areas that would require some changes.

If you are wanting to use the 125, you’ll need to pick up the correct flywheel cover and all of the parts for at least a 250 2.15:1 drive.
