I wouldn't be a 100% sure if there is an adjustment on a scooter so light as your shock might just be banjoed if the ped is bouncing around.
Have a look on the shock to see if it has an adjustment ring, it might be at the bottom. If there is, then look for grooves or slots in the outer sleeve of the shock with numbers on it. The numbers will go possibly from 1-5, if you twist the adjustment ring, (spanner might be in your tool kit) the higher the number you go then the stiffer the suspension.
If there's no adjustment then you can source a race shock off Ebay, it wouldn't be any dearer than a new one from Peugeot.
