Freestyle Rod clearance with cases when you trench for +10mm

Hi all,
someone can say me wich clearance I need to make like said in title ?
I actually have with me broken cases for +8mm 950cc (all the work done by dasa, of course not the fact the motor fail lol), my +10mm crankshaft fit inside these cases but not safe clearance according to me and the thickness of the side make me afraid to trench more.

Other question, do you know if dasa trench the same for +8 and +10 ?

Thanks for your help
