I agree less then 20 bucks prabably just the gasket. Good opertunity for sump screen cleaning. Triumph say's to renew the little screen bolts. Warp say's they are lazy apply medium grade thread locker (blue) after cleaning the complete sump with a can if brake cleaner. Don't forget the two bolts just inside the side stand a few inches more then the outer perimeter bolts. Or you will be scrathing your head. Look the sump pan.over after cleaning incase you suffered a unknown collision and cracked it. You wouldn't be the first for sure.
