Rear differential/Gear Oil Leak

[jay02904]

Rear diff. is leaking....again this time i have figured out the "inside of the screw hole" (if that makes sense...loss of words...where the inner threading is) are stripped ---- i did not do the last service on the bike the kawi dealer did but has since gone out of business. so i am left with the leak the only thing i can think to do is re tap the rear diff screw drain hole to like size #9. any other ideas?
