• I created revised screenshots of all the usual functions for our new format, like posting pictures and videos, sending private messages, etc. While videos are becoming more popular instead of posting pictures, when asking for help and advice for a specific problem, good clear close-up pictures are still the best way to convey a hardware situation.

    Currently the "attach files" button is not functioning correctly, to add pictures use the "insert image" button on the toolbar above the text box.


    To conserve expensive server space we are still requiring videos to be hosted elsewhere and linked here. In the new format it is as easy as pasting a video link in place now, and a much wider range of video formats are compatible.

1979 CM400A Winter Rebuild

It's all good. Lot of stuff flowing in these threads, especially when they're long and you miss those small details. I do the same thing.

Not a lot of news, but there is some. My contact in France was able to order which is apparently the only remaining oil cooler gasket on planet earth. I have one already sourced from that bottom end kit, but this one was cheap so I'd like to keep it as a backup in my parts hoard. Will keep you posted when it arrives. Will probably be about 3-4 weeks.

I already have a spare, but got yet ANOTHER spare of the very rare "change switch" or rather "neutral switch". Found someone who mislisted it on eBay not knowing what it was, and at a great price. It has arrived, and this one actually has the rubber boot cover. That boot is always missing on every single one I've found and every single Hondamatic I've worked on. I think they just crack and disintegrate and that's that.

I also cleaned out DSS on their last remaining set of 400A carb insulators. So I now have three sets NOS, one in use. Enough to ideally last me a lifetime, if stored properly, which they will be.

I have packages to ship out this week so I will be sending the cylinder with pistons this week. I'll throw that crank in for inspection.
 
A heartbeat to this thread. Need to find time to run out to Lowe's or similar to get some of that cardboard tube stuff to place in the cylinder stud holes and get everything packaged and ship for the machinist. Been quite busy recently. Planning to find time this week or this weekend.

Because of the fragility and rarity of the piston rings themselves that and the pistons will be in a separate package. Insured for their full value.

Bet I know where they're going.
 
In my quest to acquire enough valve cover gaskets, valve cover bolt grommets, oil filters, carb insulators, spark plugs and caps to last me literally in my lifetime (no joke) I threw in a new clutch lever rubber. To the curious, it is the same however it's about 1mm wider on each end. You wouldn't notice unless you took both to compare. But, if this matters to you then be warned it won't win Concours because of this. 😂
 
Also for the curious... I received a spare "Gasket Kit A" because the price was cheap and includes the valve cover gasket. This appears (to me) to be early-to-mid-80s stock because it has the more modern Honda logo going across the cover, but also has the 70s style "wing" logo at the top left.

What amazed me, and encouraged me to open it, the head gasket looked all black. I could not see the "fire ring" and thought this was strange. Upon closer inspection it has the sealant over it to promote a better seal. This coincides with what Mike has said in one of his articles. He said that later in production Honda started adding a sealer to the head gaskets.

I have never seen this before. Any time I've seen individual head gaskets for sale they have no coating on them. Even the later stock that I suspect is from circa 2000 era.

Just something I found interesting and it was neat to see it firsthand.
