We can usually reuse the old crank if needed when we split motors. So, press the crank halves out? What crank are you getting to replace it? Going stock or a slight upgrade? A upgraded crank cost a bit more and gives you the worry free option if you ever go with a bbk in the future. What sucks is we recycle the old, stock cranks after removing them. Have zero interest in stock motors.

This thing was abused. I think they ran it quite a while with bad bearings. Both sides were bad. I could wiggle both the clutch shaft and magneto side. Pull on the connecting rod and you could see the crank shaft moving as well. Piston was a little scored also, but cylinder looks to be OK, cast iron I believe. I am just going to put it back to stock. If I am going to mod something it is going to be an older Zuma, like those scoots.
