Regarding cavitation/frothing oil in the box , if you run the advised norm' of 1.9lts and there's only the standard breather 1mm diam hole in the lid , under competition use , yes it will cavitate . However , having been there done that , I now use 1.6lts total including 100mls ZX1 Extralube . On top of that I've drilled a 2mm diam hole in the lid then connected a small container over it , so it can blow into it then drain back(the container also has a 3mm hole in the top. Never had a problem since
