Xs400 disc Hub swap : what is compatible ?

[Blackbool]

hi everyone!

I am preparing a XS400 scrambler conversion and i am struggling to figure out which hubs could fit a rear XS400 disc.

I have heard that a YZ dirt could fit with some modifications.

Do you know the space between the sprocket and the disc for a XS400 (rear hub) ? For a YZ 250 ?

Thanks a lot for your help
