Got Pre assembled crank from sonex.therefore I skipped that section in the manual and video.was getting ready ti install the cylinders while the video played from the begining, and saw the part about removing the plugs to clean out shavings. Was wondering if sonex did this when assembling the crank. Not wanting to remove the crank and start over.

I don' think they do. When I got mine with the hub installed it still had a few fine chips that I blew out with the solvent gun.
