Was planning on a Malossi 187 kit and cam for my LX but heard a nasty rumor that the GT200 cylinder would bolt up. That brings me to the 218 kit and V4 head. Has anyone done this on the forum? I've already ordered a Multivar vari, Delta clutch and Malossi torque driver. Polini and Malossi offer gears that will bump the final drive ratio nearly 20%. The reason I want to do this and not buy a GT or GTS is that I love the LX's size and handling. Any thoughts?

I see no input so I guess I'll just go with the 187 kit and cam for now. This is my daily so it's best as a weekend project. After this and the PM56 pipe and upgear I'll decide what to do with my other LX150. I'm pretty inspired by the Sprint 300 build on the projects section of the forum. I'm still very motivated to try the 218 L/C conversion with the V4 head. I'll just have to research the right cooling solution.

I'm not familiar with the 3v head on the LX150 IE. Is this a possibility on the A/C 187 build or am I stuck with the stock, 2v head? Really bummed that there seems to be no solution to a 2v, performance head for the LX150...

Send a message to forum member "bluecloud". He has, or had, what I believe might be the most heavily-built modern smallframe on here. He started with an orange S150, and I'm pretty sure by the time he was done with it, the only thing left that was original was that paint...lol! He seemed to have modded it from front to back, top to bottom. He's your man for engine mods and advice, I'd suppose.

It does bolt up. We have a list of all the Malossi and Piaggio parts you need to use to make it work.
