Vespa px / How to install a Polini exhaust

[@gillessmeets8531]

do you know if there is a difference between Polini exhaust PX 125 and PX 200? have one at home for PX 125 and that cylinder won't fit the end of my exhaust

[@Nordicexplorer1]

Hello. The 125 exhaust won’t fit a 200. I think 125-150 are the same but they don’t fit the px 200.

@@Nordicexplorer1 Ok, thanks , i will order a Polini ( Part number 200.2023/S Vespa PE 200 Retail Price Euro 171,00 + VAT)

@@gillessmeets8531 That should be the right exhaust for your bike 👍

i have SIP tubeless rim installed. Will it fit ?

[@Nordicexplorer1]

Yes it will. It’s sip tubeless on the bike in the video

[@squeezzeee]

@@Nordicexplorer1 thanks lot. Can you give any idea why engine is bogging at 1/4 open throttle .

[@Nordicexplorer1]

@@squeezzeee 👍. Sorry, hard to give advice for that without being by the bike. Could be number of different reasons.

What about carburator?

[@Nordicexplorer1]

Hello. In this case I was using a 28 mm Smartcarb. But when I sold the bike I mounted a 24 mm SI carb with enlarged fuel chamber channel and 125 main jet. Drilled heart in the original air filter.

du, den kommer nog låta rätt mycket dendär:)

[@Nordicexplorer1]

😁finns viss risk för det. Hoppas den levererar vad det gäller effekt också.

@@Nordicexplorer1 det får man hoppas:)

@Hajime Kuma hello. It sounds much more than the stock exhaust, not so much at idling but when pulling the throttle. The sound is a bit like a two stroke dirt bike. There is two screws in the back of the muffler. In a upcoming video you can hear the sound.

[@Nordicexplorer1]

@Hajime Kuma When we get some spring weather here I will do a sound check video with idling and flyby test.

[@VespaTobi78]

The Sound is great, but the Performance is not really good

[@Nordicexplorer1]

I’ve also tried sip road 2 and I think they perform about the same.

[@Nordicexplorer1]

I’ve ordered a sip road 3 for my px200, it will be interesting to see the performance of that.
