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.
PIaggio OEM 200 Cylinder Kit. PI844113 844113
"

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.

I have a problem with the rubber intake between carburetor and cylinder head. It is made of soft rubber and cracks under vibrations because there is no support from the other side of the carb. As i said before, i use a filter pod and not the factory filter box that has a hard intake support tube.
I tried to modify an after market intake for the Yamaha Majesty 125, but there is not much space in the bucket under the seat, so i have to decide if I modify the Yamaha's intake or the bucket under the seat.

Coyld the problem be the added stress put on the rubber intake due to the pod.installation The factory intake also supports the carb. Does the pod have something that allows it to be solid mounted. If it is , could you add a rubber gasket to the mount to reduce vibration?

It's difficult to add a support bracket to the pod and there isn't an easy place near it to fasten the support bracket.I have to make a more solid intake to support the weight of the carburetor and the pod.
In the meantime i always win at the race of the traffic light.

I solved the problem by adding 4 gaskets between the rubber intake and the cylinder head.
Now, the PE28 carburetor stays high, and it doesn't touch the cylinder as it vibrates up and down.

This is Great info....
Wish I would have read this before buying the Mallossi 187 B bore kit (for a 02 ET4 150cc). That totally makes sense and is a much better idea... Not to mention you gain the additional real estate..

I decided long ago to buy an original Piaggio cylinder piston set from Liberty 200.
It has 2mm bigger diameter than Malossi's cylinder and it is much cheaper:154 euros when malossi costs about 300 euros!
Unfortunately it was not available at local shops for many months and Easy parts company returned my order back after some weeks of waiting.
Now it is avalable but i have already bought a Malossi kit.

Liberty 200 cylinder swap is a common modification and i have friends that have been satisfied with it.
All air-cooled leader engines(125-150-200cc) have the same cylinder head and camshaft so this is not a problem.

Did the Liberty 200 have an 4 valve head? I thought I had read somewhere there had been a Leader-based Air cooled motor with a 4 valve head, but never heard anything more about it. Getting the engine to breathe better has always been the weak point. I know you can get a camshaft to address that, but haven't taken that step yet.

My Fly 150 with the 190 kit and Polini upgear will hit 70+mph.

I thought reviews on the 200cc cylinder were disappointing, likely due to the lower compression ratio compared to the Malossi.
