This came off my 2.2 L /6 engine with 901 trans. I bought it from Don at Air Cooled Classics as he was selling out all his stuff, and used it 1 weekend before we decided to go another direction with the entire engine.
He said it weighed 9 lbs. I never weighed it, but it is definitely lighter than stock. You can see the machine work to lighten it.
$270 shipping included.
