cylinder off but seems odd!

Postby rob h » Sun Jun 05, 2016 7:26 pm

Started fitting a pinasco kit to my 2009 150 3 port. Piaggio cylinder off, found I have the larger ports what a result. The crank is already replaced with a standard quality Italian. The vespa cylinder ports look half the size of the lml case ports. The pinasco cylinder ports are bigger again, possibly 20% bigger. However with vespas the engine case that match the cylinder are smooth, the lml cases seem to be rough faced possibly casting lines. Can anyone confirm this before I start sanding the faces. Rob
