I finally opted to buy a Pinasco 177 kit to go on my LML 125. Also bought a 26mm SI with a range of main jets and already have a Sito Plus on the bike. Thanks to contributors such as Curare, Adrian Newnham, Vespadoc and others for adding to my knowledge of Vespa (LML) tuning and helping me to decide to buy this kit. This forum is invaluable. I’ve only ever worked on Lambrettas but use the LML for going to work (it was cheap) and I’m very pleased with it.
The LML is quite new so I don’t want to take the engine apart to fit a long stroke crank (just yet). Too busy with my old Lambretta for now. I’m hoping the Pinasco kit and carb will just bolt on and work, more or less. Setting up the carb I can handle. I noticed that SIP advise fitting a long stroke crank with the Pinasco 200 kit but do not say the same for the 177 kit in the advertisement on the site. Although, other forum contributors advise that one is fitted with the 177 kit.
Any advice would be much appreciated.
