All Vespa's old or new run without need of lead as your engine internals are lubricated by either the gear oil or 2 stroke oil.

don't worry -the clunk noise is typical when changing gears on a Vespa 125 PX
- it is due to a very old fashioned construction in the gearbox (1940ies) see pictures:
you have to get used to that or change to a newer automatic type Vespa....

if you have experience as a mechanic you can do it by yourself, but otherwise it is better to have it done by a pro, as the brakes are a main safety item....
