Hello, yesterday evening I apparently scrapped my gearbox or at least my clutch from my Vespa PX 125 E lusso. Since I always wanted to give my Vespa more power this is now the perfect time, because I will disassemble the engine anyway. Become 18 in 2 months and have the A1 note. Now my question: Can I have my tuning entered and how does it work and what does it cost? Would cylinder carburetor u change everything that belongs to it and finally so on my – for the tüv – allowed 15 HP come. Is that possible? Greetings hannes
