Vespa Primavera 2017 4t last model year with carburetor. I made another thread with a similar question a week ago I think

It works! 55kmh-ish top speed on a flat road probably more, now I just need to wait for the lighter rollers for better acceleration and hill climb speed... currently 17kmh on average and I'm done with mods for a while.
