Xs1100 header on a z1 900

Somewhere I could have sworn you can fit a header off of a Yamaha xs1100 on a 900 or 1000 does anyone know if that’s true? I have a chance to get a 4 into 1 kerker off of an xs1100 for $100 it’s like brand new. All I’m really concerned about is if the header portion will bolt up?

For that price, I would take a chance. Even if it does not fit, you should be able to flip it for a profit.

Speaking of XS 1100!
We used these pistons back in the day! Cheap Big Bore Kit!
I forget the thousandth's of inch in decimal?  Or 71 or 71.5 mm?
But they are exact fit wrist pin height to the Kaws,  "ART" pistons.
Just bore to fit!
It came out to 1060cc's.
I remember selling a set on eBay over 10 years ago.

 
Livin in "CheektaVegas, NY
Went thru 25 of these in 40 yrs.
I SOLD OUT! THE KAW BARN IS EMPTY.
