I riding two years on a stock 2005 PX 150 with a Sito plus that is mint and has about 20k km. I did the unthinkable and ran out of two stroke oil. Now I have an excuse to install a bolt on kit, I have decided on a Pinasco 177 Au cylinder kit. I chose this kit because of its reputable high quality, reliability and longevity for every day riding. I am interested in optimizing the mostly used low-mid power range band for city traffic and steep hills. Also, I want a bit more on top end and to be able to cruise at 100km/hr with no issues in overheating. Previously, I have installed a Sito plus and install a 102 in the stock SI 20/20. I am a big boy at 155kg so cruising at 100km/hr was not feasible, however I was satisfied with it mid range torque and power for city riding.
My set up to be for now? Pinasco 177 Au cylinder kit on a stock motor, 20/20 SI carburetor and a Sito plus exhaust. At this point I have no interest in machining, and modifying other than bolt on. I look every where on the net and I can't get info on proper jet size. Also, I am new to Vespa so any information and advice on a better and balance set up will be greatly appreciated; just remember my criteria, I am only interested in the best bolt on only, for every day riding.
Than you and Best regards
