1980 750F-messed up spark plug threads

[CB750Winger]

   I'm thinking about buying a 1980 CB750F for around $300. The owner says it's good shape but he tried to change spark plugs and broke one off, tried to drill it out, broke the easy out off, just plain messed it up. I would plan to pull the head but is it worth trying to save? Not sure how I would get the easy out removed and it sounds like he has "ovaled" the whole. Any suggestions?  Thanks!   Paul

  I'll check out the head availability and think about it. Thanks for the reply.

There are a couple on eBay right now.

You can also take it to a machine shop and let them take out the tap, weld up the hole and re-tap it.

  Thanks polymer. So I guess the 81 is the same as the 80 head? I have not seen the bike yet so I'll go take a look to see what else is involved. I don't have a problem going through the motor, done all kinds of them including Goldwings. I enjoy restoring these great bikes so I'll give an update on what I find out. Thanks again for your input.

I'm pretty sure they are the same but check with a Honda dealer to be sure.

Yes.  79-82 K/F/C same (for the 750)
