Just picked up this CB500 for free! It has (had) a seized motor caused by rusted pistons. I just got it home on Friday. I currently have the top end off and am planning to do a full rebuild. My only problem.... I just started getting familiar with the sohc4's... this motor looks totally foreign to me. I will also be posting this project on the Honda Twin forum.
Here's my plan of attack for the motor:
• Lap valves
• Clean up pistons and see if they're reusable
• New rings
• Hone cylinders
• Replace all gaskets
• Split cases and see what needs to be replaced (If anything)
• Get new hex bolt kit for all engine hardware
• Then all general maintenance (Set timing, valve clearances, etc.)
Am I missing anything?? Here's some pics of the progress so far:
