Cb450 bober project, frozen piston
« on: November 14, 2013, 04:44:54 PM »
So I've started this project, the frame is stripped, and the engine is out. Taking apart a weather ridden engine, both pistons where frozen. I got the header off, no problem. I've soaked both pistons is some PB blaster, one is free the other is being more difficult.

I'm hitting the top of the piston with a stick of wood and a mallet.

Any ideas or better solutions?
Current ride: 78' Cb750F
