Hi all newbie here from Australia my name's Sam and I'm 30 recently after a few sleepless nights I thought it was time to try joining two cag 49cc engines together but then ran into a problem joined the crank shafts together so I have come up with this. Using two motorised bike magnet and Magnetos. The pros easier to join the shafts. Cons no cooling. But hey it's a work in progress
