Hello to all: This is my first post and I hope you will excuse my english. I am from Sevilla, Spain, and I drive a Vespa PX 200 E 1995 to work every day: I need more power. I have a Polini cylinder kit (140.0082) and a Polini exhaust. The question is: what else do I need to make it run perfect? No engine porting modifications, same carburator. Do I need a new head? Will a head gasket ( 1,5 mm) do it? Timing 18º'? What jets do I need? etc. Thank to all of you, and excuse me for been so telegram-writing.
Thanks, I am expecting your answers.
