MINARELLI engine with staggered ignition timing, for PIAGGIO Maxi 2T, Give your motor ca. 3° earlier ignition timing for higher rpm‘s and increased top performance! We think this is best PIAGGIO/GILERA and MINARELLI 2 stroke motors and, ideally, with MALOSSI Digitronic. TOP PERFORMANCE offset wedge. I was buying some stuff from SIP scooter shop and i came across this woodruff key .Has anyone ever tried this with any results ?
