has anyone ever run a crankshaft that got its flywheel turned around?
#2...an Atlas crank in a commando?
I am working on a 72 and despite everything it still has strong vibration up to 3000, by 4500 it finally begins to smooth out. I am using a single Mikuni from another 750 so I know the carburetion is correct. The plugs blacken fairly quickly, my theory is that the vibration upsets the carburetion which causes more vibration.
