drain plug

order one from a yammy dealer. would save u alot of time and you wont pay for shipping and you'll know its not striped or anything.
 
Go to NAPA and get a BK 704-1912 (size 12x1.5). I think that is the right part number if it is too small it is a 14X1.5 and they have those too. You will have to cut the pilot point off with a hacksaw or cutoff wheels so it clears but it will work. I have used them many times. MAKE SURE YOU CUT IT SHORTER THOUGH OR IT WILL HIT THE INTERNAL COMPONENTS!
