Here we go,
Of course no pictures until everyone has assured me that it can't be done.

So I've found the solution to the 13 inch mounting bolt for a VB1T to install a later engine inside, in the process I've discovered that it's known that these little scoots flex on hard cornering right back there in the little frame section we mount our engines too.
Piaggio don't cry, what I'm about to reveal is my project plans.
I've recently aquired a sad P200 block and it wasn't my intention, but provenance has awarded me the opportunity to have a perfect mockup tool.
I was using a True Veloce 3 Port engine for this mock up, but it's heavy and bulky, at one point I considered tearing it down (it's a Runner) to facilitate measurements and fitting! But alas we have ignition captian!
So, with a bit more experience looking at this project now, I see it's impossible to fit an engine in there correctly under the hood unless you cut and weld.
But where do you cut and what do you weld?
No where right?
Bah.
There needs to be strength and clearance in the same place where the engine hinges from, if you'll look at any Vespa they've changed that area over the years and not allways for the better.
But it can be done, I promise. And it can look right.
The end (engine) game here is unknown as of yet, but the picture is that little red scoot on 8" hauling (my) ass, sidecar for parades and such, that option is waaay down the line.
The next post will have pictures, I promise.
Here's the recap

I've got a bigger shed now, and summer is coming, and so is a scooter rally to prepare for. Hope to make the TDI rally!
