Hello all.
If you own a Suzuki Ozark or LT250; The 12mm drain plug only has about 10mm of fine thread due to the case design.(Horizontal hole in thread area for oil to drain from right case half) I recommend replacing the crush washer every time to minimize damage. I'm very carefull and I managed to strip the plug with a 1/4 drive ratchet.
Hope this saves someone some grief.
