1978 CB750F Piston rings

[Buff CB]

After pulling apart my Honda I started looking for all of the replacement parts needed to build her back up again and I can not find piston rings for this machine anywhere! Apparently 77-78 supersport rings are super rare now and they've all been used up.


I found this original post http://www.dotheton.com/forum/index.php?topic=13102.msg122983#msg122983,
and tried every source there. The Honda shops across America don't have anymore in stock. The David Silver Spares shop in the UK said they can't help because I have an American version (is that really a problem?).


So now I ask this forum if there is somewhere that might have them. Is it really that bad if I have to use the old rings? This build is dead in the water right now because of this conundrum.

Dude! I'm in the same boat! I need some help.

I ordered some rings from total seal. Then cut the last ring to fit the diameter closest to the bottom ring that they had

I'm looking on ebay and found this part number 13011-392-004. I'm not sure if that'll work but it does say it fits the 1977 and 78 cb750F, which is what I have.

Those are the same as I have ordered on ebay, they should work fine

Let's hope so! I'm going to try to work on it this weekend. I'll post an update.
