Hey guys, I'm new to the forum and love this post and the detailed information you have all posted.
I have an 09 Fly 125 and like everyone else I want more grunt out of it. Other than this forum there seems to be limited mod info available for the Leader engine.

I was looking at my first major mod to be the Malossi 190 cylinder kit. I had considered the Piaggio 200 kit but a scooter web site stated:
"We hate this kit and don't recommend it to anyone. In our experience, this kit lowers the compression so much that the bike performs almost as well as a stock 150. The other 200 kit out there, from a well known Italian performance parts manufacturer, appears to be this same kit in the seller's own blue box. Nobody who has bought this kit likes it. It might be an improvement if you live in a country where gasoline is 75 octane, otherwise, it's horrible. Do yourself a favor and get the Malossi kit. It does make a big difference.

I see several people here recommending the Piaggio kit. Who has had success with the Piaggio kit? Anyone know if it is as good as the Malossi?

Get the Malossi. That's the better kit.

After 10 years the project is still running good.
I am not happy with the quality of the malossi kit,i suppose that i have to change piston rings as the leak down test said to me.
