How do i remove the steering lock from a vespa px 200

The clutch release bearing is noisy, did you replace it?

there must be holes in the muffler caused by rust - replace it with a new original one...

no, it's not!
- do you have the later type of PX with a separate oil-tank which mixes the oil automatically to the gasoline or do you mix the two-stroke oil in a 50:1 ratio by yourself to the gasoline tank?
- if you have the 2 tank system you need to fill up the oil-tank always with two-stroke oil!
did you ever made a service on your Vespa?
like changing spark plug, replace engine oil , clean carburetor and adjust ignition etc?

the newer PX have the side cover latch under the seat
- see picture

the older ones have them at the lower front of the side covers
- see picture

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....

You should use [Non-Detergent] SAE 30 motor oil according to this site:

Good luck

To replace the mudguard is easy enough but takes a good while.
Remove case from the handlebars (mirrors first then screws and split).
Remove the bolt that holds the handle bars to the steering column and remove the handlebars.
At the top of the steering column you need to unscrew the round nuts that tighten the steering column.
You need to disconnect the brake hose and cable (later you will need to bleed and refil the brake fluid).
Then you need to lift the frame up from the front so that the steering column slips out, be careful not to lose the bearings.
The mudguard is held on with (i think) 2 bolts. remove these and then lift the mudguard up the steering column. drop the new one in it's place and put everythiing back together in the reverse order you took them off

Just had the same prob.

It could be a broken solder joint on the lighting coil on the stater plate.

Remove the flywheel and visually check. The smallest blob of solder cured this on my Px 200 disc.
