I am on the search for 1978K rings as well...I'll keep you posted

Speaking of rings...do rings vary greatly in quality? Are they better brand or brands to watch out for?

I was having the same issue. I ordered some off of e-bay.... some no namers and they didn't fit properly. I like to stick with OEM as much as possible, here's a site that I have come across and I've sourced out a pile of OEM parts including the rings.

www.mrcycles.com I checked for you and they still have them:

in my mind $33 isn't bad for an OEM set. Good luck and hopefully this helps.

01 RING SET (STD)  13011-374-000  004 $33.49

If the 78 K uses the thinner F2/F3 rings then contact member wohali. The reason they may be "out of stock" is they may have been discontinued by Honda.

Thanks everyone...Dumb question: how do I know what Rings I need?

I am 99% sure my engine is stock so I guess it is the: 01 RING SET (STD)  13011-374-000  004 $33.49

But why are there 4 options?



Is that just for each piston and they are all the same?

The way i read that is simply they have all been replaced by  -004 and that's what you'll get if you try to order the others.

The way honda part numbers work: 13011=ring set; 374 = bike model;  004 =modification

If you think you need 374, and they are listing 392, I'd have to be sure they are interchangeable. In other words 392 is not the same motorcycle as 374.
According to this (scroll down to product code link and open it) 374=CB550; 392 = CB750F/76

You're probably OK with the 392s for the 78K. But you mentioned 374 which threw me.

Yes i see in the codebook, 78K is 405, which your post shows has been replaced by the 392s. So you're OK.
