As others have said, replace the copper washer and see if that helps. I would not recommend going to a bigger size; the drain bolt area on CRF crankcases isn't giant, and going much bigger to an M10 will be pushing it.
Instead, get a helicoil repair kit, a new washer, and a new bolt.

Cheap repair kit, but probably overkill for a single hole, and I'm not sure of the thread type of the drain bolt: https://www.amazon.com/Tek-Motion-Stripped-Rethread-Helicoil/dp/B018LMAXFU/ref=pd_lpo_vtph_263_bs_t_1?_encoding=UTF8&psc=1&refRID=P3ADEYE2MJQNFTSSY1E3
Best of luck.
