Hey everyone. A few months ago I bought a low Mike Ď05 PX150 series America. Iíve been tinkering with it since the weather is warming up, trying to get it tuned. The engine cover has this sticker on it. The bike had a bunch of misc mods on it. Curious if an engine swap was one of them?

Hereís a pic of the engine.

That paper sticker came on all the Ď05 PX150ís. Normally they just decompose off the shroud over time. That engine looks all stock from what I can see.

Thatís a PX200 motor. Part code (4870445) confirms that. Take a pic of the exhaust near the kickstart...

Hereís some pics.

The JL exhaust is also for a P200 according to whatís stamped on the side of the engine.

Definitely a 200 and I also see an aluminum cylinder so it's also kitted (Malossi, Pinasco, etc.). Very nice...

WTH! Thatís crazy. It explains why this thing isnít running right as I try and tune it. I assumed it was a stock Ď05 PX150 with an exhaust on it. It sat for years. I bought it from a millionaire collector from NYC who kept it at his beach house in the Hamptons. I replaced the fuel line, fuel tank, and fuel selector valve. Disassembled the carb and replaced the jets with jets that would work well with a 150 engine and a slip on exhaust. It has run like crap ever since. Acting very lean last fall when I bought it, so I parked it for the winter.

Guess I need to start over and very all the carb components.

I'd start with a 55/160 and a 160/BE3/130 combo...

Anyway to find out if the gearbox is a stock Ď05 PX150 box or a box for a 200? I understand the 200 doesnít play well at cruise speeds when using a 150 box without changing the 3rd and/or 4th gear ratio.

Iím stoked if this is indeed a 200 engine, especially a kitted one. I paid $1800 for this and it has 160 miles on it.

Since there's the part code I mentioned on the flywheel cover, it's a complete PX200 crate motor that was put in. Piaggio used to sell them as spares. They are still some available here and go for 3,5k euro. You definitely got a deal there...

Wow. Now Iím more stoked and canít wait to get this thing running! Guy I bought it from said he had $10k in it in labor since he bought it. Said he took it to a motorcycle shop in the hamptons to make it run. Had no idea what was done to it, just that it didnít run again after sitting all winter 2018-19. I thought he was exaggerating and/or being ripped off by his shop. Now it makes more sense.


Mind if I pick your brain about some other things on it? Any recommendations on a spark plug? I put a new oem in from scooterworks for a stock PX150. A NGK BR7HIX. Would something hotter or colder work better? Also curious, should the carb be a 24 or 26 sized carb?

Since it's a PX200 and kitted you need a different plug (long thread). I'd go with a B9ES. Standard carbs for these motors were 24...

If you havent already, try removing the plastic cylinder cover. Its a few screws and one bolt by the spark plug. Then pull off and you can see the cylinder and some kind of manufacturers stamp in it.

A 24 or 26 carb could work. Larger is preferred but the 24 came stock and matches with everything else in line (air box, inlet).

If its a 200 you want to switch plugs entirely. Go to an ES plug. B7ES or B8ES

Itís a Malossi! Says something else below Malossi. Looks like brevette but I canít read the rest of the letters, they are hidden behind the cooling fan.

Malossi 210, from the stamp it looks to be the "old" one. The other word is probably "brevettato" which means patent in Italian...
