yeah i was supposing 1105 because of what you said plus the 73mm is 1105 in wiseco i think-but these aren't stock for anything else as far as you guys know? definiately aftermarket stuff?

yoshimura was a big supplier of hp parts in the 70s for kaw stuff but somewhere along the line in late 70s-early 80s they went to the dark side with that damn wes cooley and a couple others and started working with mostly suzuki stuff !:laugh:i still love their old 4 into 1 headers from the 70s B)
