Alodine, I suspect, I haven't worked much with magnesium, but have used Alodine on aluminum, and it goes straw colored after being treated, like you said. I was just curious about the black final coating, since magnesium corrodes more easily or quickly. It's not anodized is it?, no matter/worries. It's a marvelous looking motor you're putting together, top-notch for sure.

Seems a shame to hide that lot under a seat and fuel tank :-(

Hi, No that is not me, but Fritz Egli Jr who built the engine for me.
I was not that calm

Yes I sure am. Fritz put it in his own frame just for start up and later dyno tests. (I see you are probably Swiss like him).

I am an expat Brit who considers himself very lucky to live in one of the most beautiful countries on planet earth. If you are coming to collect your bike, I would love to come and see it and meet you and Herr Egli jr.

Thunderation! Nice bike. 
I remember the excitement of the big startup, it's like being a kid all over again.
Which T.Prince cam did you choose? I think he has (had) about half a dozen profiles.
He has sold everything off and doesn't plan to make any more parts.

Did he sell his company, or just retiring do you know?
He has retired. I was recently contacted by a fellow who wants to build a big cc Egli or possibly a Norvin. I gave him all of my info and contacts. Other than the cases( Molnar) much of the rest of my engine is from Terry. This time around, Terry did not have any parts to offer at all.
For ease of registration, the fellow is going ahead with a Norvin, not sure at what capacity.
Those Prince heads were fabulous, especially the last couple of batches after Steve Hamel's input was added to the mix. Steve modified Terry's heads for Bonneville speed runs and eventually got 120bhp on gasoline with 998cc.

Nice one Buellingvincent, you must be rather pleased to say the least!
Can you remind us of the spec you ended up with?
And what you’re going to do with it?
That chassis of Fritz Jr looks purposeful and tidy.

I've heard that same number used for MG weight saving.
It seemed a lot as my Al Molnar cases weren't terribly heavy to pack around.
On checking, standard Al. cases are 33 lbs or 14.7 kgs.
Mg is 33% lighter, so if thicknesses were kept the same the weight saving would be about 5 kg .
I recall having a conversation about this with Andy Molnar when I was ordering cases.
Andy Molnar felt that Vincent cases would require some beefing up if done in Mg .
As he pointed out, Vincent cases are not webbed whereas Manx mg cases are heavily webbed to make up for the relative weakness of magnesium.
He figured that the large open Vincent cases should be thickened plus have the webs added if cast in Mg.
By the time all that was done, the weight saving was quite minimal.
Then there is the expansion problem.
As he said " We have a hell of a time holding the bearings in the Manx engine, it's always been that way".
Anyway, he talked me out of Mg, which was available at another supplier at the time.

118 Nm torque at 5300 rpm is a most impressing figure for a 2 valve engine. The power curve will remain high, actually it's rising all the way to 5800 rpm and probably well beyond. I am amazed! Tester probably ended the test at 5800 rpm to spare the freshly built engine.
For comparison, Triumph Truxton 1200 churns out 112 Nm @ 4250 rpm and it's an 8-valve motor w/EFI.

What kind of stator is shown in #7 ? I thought it went inside the pulley, but your comment seems to indicate there is a second alternator driven by the outside belt teeth. Anyway, I see your point about differential thermal expansion. The clutch hub will heat up with a large time delay to the crankcase and a different CTO to boot.
Couldn't the stator shown be made to supply all the current needed for a bike? I like the idea of having it inside the pully. Where have a seen something similar - was it on a HD?

The large displacement is easily noticed - beautiful !
There is a disturbing clatter in the video - I hope Fritz Jr. is able to silence it.

Yes it is from the belt/pulley for alternator. Most probably. We are aware of that. Will be fixed.
I have the same set-up on my Black Shadow. I.e. a double sided belt and pulley for the alternator. The difference is a slighly bigger pulley on the crank and a size longer belt. In short, I slight stretch in the belt. No issues with noice in that one. On the 1330 in the video, the belt has a slack and that probably creates this noice.
