Fiekie, that is true.
Thing is he got just the heads from there. He is building eveything himself. There is quite a bit of modification to both the head and the block. And the other problem is that there is not allot of these bikes around in SA.
But that said, I have seen quite a few for sale on gumtree. And if you get a running rike. Then you have the carbs/fuel injection and everything that you might need on the head side.
