some interesting banter a week or two ago about exchanging cylinders out or reboring the original. When there is a decent aftermarket, boring does not always make financial sense. however, there are a few platforms for Vespa that either few or no choices exists for new cylinders.

I picked this 104 Allstate up last year, my third pre-1954 Allstate i own. it's a bit rough, but i love it and it really tells a story. They top end was seized and with the help of my Oxy-Acetylene torch and a block of wood, i should it who was boss. Now, there are no after market cylinders for these pre-1954 single port engines. . . none, so you have to be real careful getting things apart.

well, it was never soft seized believe it or not, it was oxidized. the conrod and bearings would not move at all.

i have cleaned up the cylinder with a light hone and am using the standard size piston. The exhaust and inlet are both cleaned up. New crank shaft with the additional of a needle bearing for the small end; original came with a brass bushing.

Last three pics may be new to a few of you on this board. Single port engine before i mounted the cylinder; yes, one big port. Fully CNC machined high compression that a friends makes is a nice additional to the original cylinder. Last pic is interesting: i machined an original flywheel to fit a Vespatronic ignition; fit and finish looks stock.

enjoy the pics.

Interesting, the two ports Iíve seen pictures of have a port on both sides but no middle. This has a middle with no sides.

In general: single port up to 1954, then two ports from 1955-1957.

Wow, that's a pretty amazing amount of uh...patina. It's super cool though. That particular scooter didn't happen to have a short layover in the PDX area last year before you got it did it? Cause i saw a very similar one at a friend's house.

So Beautiful. Character for days and days. And the attention to detail to keep the irreplaceable stock components and engine are superb. I'd love to see and hear this oldie sputter to life.
