Thanks very much for all the kind words.
Keiffers model is truly amazing. Thanks for the link.
Im not sure what kind of power comes from this engine. Maybe a dyno could be next...
Good eye Jason, that wire should have sat on top of the 123 block. Instead of 2 square lengths of alloy I made a rectangular frame which I think adds alot of ridgidity to the engine. And like Mati said its not a scale model but an interpretation and the frame is meant to display the engine.
Here I have marked the downtube for rough cutting;
And then set the vise in a toolpost to a half inch centre line;
Then set the tube inline;
And swing it to the angle;
And then "fish mouth" it with a 3/4 inch endmill and 50 thou bites;
And it fits nicely;
A similar approach was used for the downtubes, Just a little more grinding and fidling;
Here you can see where I have had to shim the kick start assembly to clear the bottom tubes;
The head tube will also be shortened.
Not a lot of progress lately. I've been busy with home repairs and my latest obsession, building a 1/4 scale RC buggy like this fellow;

And if anybody knows how to turn a wiper motor into a servo like he did I am all ears.
Thanks,
Kevin.
