I'm building a chopper and need to cut and fit a piece in the left crank arm to widen the space for the engine. Wider cranks available will not go far enough. Mine is a 3 piece crank and the arm appears to be a casting or a forging, I'd guess casting. I want to keep the crank arm the same length as the right side is now by cutting the arm and welding on a piece of high strength steel tube and weld the pedal holding piece back to the added steel. Has anyone done this? I do not weld nor know anything about welding so I need to know if these arms are weldable with out softening the arm too much. I know there are a good many welders in the forum and hopefully some one will enlighten me before I cut the crank. Thanks guys!
