Derestrict a Piaggio 50cc 4 stroke scooter, Zip, Fly, Vespa with a CDI Single cylinder 4 stroke scooters like the Piaggio Zip, Fly and Vespa S and LX etc have been hampered in their already feeble performance with some other niggles just to make sure you really know that you are going slow enough for a cyclist to overtake you. fastbob.

The very fact that its only 50cc is a restriction in itself . 1) start at say 120 which you know is not going to be too small and ride the bike for a while. 2) drop 5 sizes and test again if it doesn't ride any better with the smaller size go back up a little and stay there. 3) if it rides better go back to 2) and keep repeating with a slightly smaller size. .

Open up the Vespa engine case and locate the outer engine pulley. One option if you want to keep at the 125cc size is to change to a bike with a manual transmission like the bigger motorbikes. Some of these bikes can get closer to 100mph but most 125cc bikes and scooters all tend to max out at 70mph. At higher speeds the manuals don't sound like they are working as hard as a scooter does. I think 17/40 is the stock gearing. Mine saw. 160klm/h several times when it was fresh and I was fully tucked in with a run-up. So definitely maxed out. I'm going 19/43 with 415 sprockets as I'm going to. put a new piston in it and set up the squish to 0.8mm. More power, more speed.. 08-17-2015, 04:05 AM #11. 364. it probably has a CAT in the exhaust still which just kills them. your best bet is to go on tjtuning forums and look there. 09-26-2010, 03:41 PM #3.
