Hi, Saleh that all depends on your current muffler if it's a stock OEM muffler that is in excellent condition then you would have to seek the advice of a muffler expert to fabricate something for you but if it has rusted holes or has a broken baffle or you have an aftermarket performance muffler installed then a new OEM muffler would quiet down the offending noise..

2011 Vespa PX 125 will not start just clicks

Hi, Tim before testing any electrical component in the Starter Circuit it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead-acid batteries. Depending on battery voltage starter relays and starter solenoids can make the same noise when you hit the starter button. You can easily determine which one is at fault by two simple tests:
STARTER RELAY- place your thumb and index finger on the starter relay and press the starter button, if you feel the click then the relay is faulty and needs to be replaced.
STARTER SOLENOID- bridge the positive and negative poles of the solenoid with a small screwdriver if you get a loud clunk then the solenoid needs to be rebuilt or replaced as necessary. If the engine turns over then replace the starter relay.
A motorcycle starter relay is an electronic mechanical switch that has a small coil winding around a piece of metal that requires low amperage and thin wires to be activated. When you turn on your ignition switch power 12 volts is sent to the relay coil which in turn becomes a magnetic contact point that pulls a spring-loaded contact point to itself completing an electrical circuit that allows more amperage necessary to be accessed by the starter solenoid which in turn acts in the same way as the relay but on a larger scale with its stronger heavier contacts making available the necessary amperage to turn the starter motor. If your battery has low voltage it, in turn, makes the magnetic contact point weak in trying to pull its counterpart to make a connection. These relays are usually encased in a plastic housing that is sealed depending on the quality of the product. When activated they will produce a small amount of heat to their metal components which in turn can create the perfect environment for condensation to form depending on weather conditions and how careless you may be with a water hose or sprayer while washing your bike. After a period of time, several months to several years depending on the circumstances this condensation is the starter button for electrolysis and the slow build-up of corrosion which ends by preventing the magnetic contacts in making a solid connection and alerts you to this situation with the customary greeting "CLICK or BUZZ" if you get a single loud "CLUNK" then the starter solenoid is at fault and needs to be rebuilt or replaced as necessary. The relay is inexpensive and needs to be replaced however in a pinch they can be forcibly opened cleaned and resealed with silicone. In a nutshell, motorcycle starter relays take in low amperage and send out higher amperage when activated and for curious minds, the voltage remains constant at whatever your battery reads at the time.

2005 Vespa PX150 reissue. Oil is leaking onto the exhaust, causing smoke. Where is it coming from and how do I stop it? It appears to be 2-stroke oil.

Haha, you can't be serious! The Vespa has a two stroke engine, and with out oil mixed with the gasoline, the engine will seize solid. You may have too much oil going in which is not being burnt in combustion, and is condensing on the inside of the exhaust, enough to drip out. That is far better though than not having enough oil. Have it professionally serviced and the oil correctly calibrated.

If you mean it is dripping onto the outside of the exhaust, that is a different kettle of squirrels. Find where the drip is coming from and tighten up the union. The tank is quite small and you will see a pipe going to the pump and then to the carb intake manifold.

Vespa px150 2014 model not running smoothly and feels like it is missing especially at low speed. fitted new NGK BR7HS which seems to be the right plug.

Check your fuel filter and regap your new plug. There usually 2 thousands of an inch off what there suppose to be. If that's 87 octane gas it could have water in it.

Vespa px150 drive belt or drive chain?

- the classic two stroke engine Vespas (since 1946 to ca. 1981) with gear shift at the handlebar have a direct drive to the rear wheel axle without any belt or chain.
- that is unique on scooters - but the newer models like ET4, LX, GTS etc. have now an automatic transmission with a variator belt.

Tune up a Vespa

That's like asking for the Holy Grail ! All i can suggest is to pore through the web and absorb all the ideas and suggestions you can. Save up lots of money while you are doing so. You're gonna need it. Dismiss the cheaper tips and tricks and buy as good a quality exhaust, carb and cylinder kit as you can afford. All depends on what you expect to achieve and how much you've saved. Every scooterist who has tried to tune a Vespa has their own favourites and recommendations based on experience. But every one is different as is every Vespa so these vary wildly. If i was to give you one big piece of advice it's this ......................Keep two fingers on the clutch for when it siezes !!!
