Question for anybody who wants to help me out. I’ve got a '74 Vespa 90 that came kitted with a 133 Malossi, 12V ignition, Leo Vinci exhaust, and a 19mm Del Orto. It is pretty fast, like 60 mph or so, but I want faster. I’ve added bitubo shocks front and back and Michelin si4 tires, but I’m new to the scene and wondering about: crankshaft, flywheel, carb, and exhaust. Any advice would be appreciated!!
