Porting the BGM177. The VBB gets a new jug.

I had to crack the cases on the motor in my VBB, and along the way, discovered that the Malossi 166 I had on it had taken some damage when I sucked the screw into the intake.
So I decided it deserves a BGM177. Also, I happened to have it on the shelf, because reasons.
But I can't just bolt a kit on for multiple reasons, not least of which being that the ports wouldn't match, so I transferred the transfer ports onto a spacer, then used that to get the shape of the new ports.
And then there was dremeling, and now I have a new top end. Yay!
