XR Zilinder u. Kopf fur XL?

[Jaap W]

Entschuldige, mein Deutsch is nicht gut, ich wol es in English schreiben.

I own a 1981 XL500S and I recently bought 1 black cilinder, 2 black cilinder heads and 2 valve covers (?). I think they are from a 1981 XR500. I would like to know if it is possible to use these parts on an XL. As far as I can see, apart from the color, the cilinders are identical, but the heads aren't. But when an XR cilinder can be mounted, I can use a XR head and valve cover. I think I can also mount the carburettor.

I have two pics on my site:

Anyone?

I also bought an XR valve cam. Can I use this one on my XL too?

Danke schon,
Jaap
