I feel pretty stupid; but where's the Oil Drain Plug located on a late model Ultra Classic?

 

It is on the left side front of the oil pan. It is a 5/8 bolt head with a 3/16 allen head in the center of it. It faces the front of the bike not on the bottom but front side. If you have your owners manual or even better a service manual it shows all the drain plugs and what size o-rings you should use on them etc.

If you plan on servicing your own bike the service manual will be the best $50 you ever spend on the bike.

Good Luck!!!!

 

Amen, My Brother!
