Default Pinion(s) position problem on Serpent 733

I have a Serpent 733. I installed my motor last night "Sirio Evo 4", and noticed a problem. No matter what I do I cannot get the pinions on the centax bell to line up correctly with the first and second gear spurs. The pinions stick out past the spurs by about a full millimeter when the bell is up against the thrust bearing, like it will be when the shoe is pressing the pressure plate, under acceleration.

The stock 733 motor mount is machined to allow only for front and rear positioning of the motor. It will not allow for right or left. Which is silly.

I have double checked my centax assembly to make sure everything is to spec, and its right on! I have even shimmed out the spurs somewhat to try and make up for the built in slop there. I could drill out the motor holes or the mount but would rather not. Is this normal? Has anyone else had this problem?

Sirio crankcases are different than the other majors, You will need the Sirio mount.
