NOS Exhaust Nuts

Post by ajs350 »

I bought a set of these exhaust nuts on ebay but when I put them on the bike their gold color just does not look right. Are they supposed to be gold or are there other vendors who sell the silver/grey colored nuts that would seem to match better?
Thanks
Ross

Ross, these are pricey but they look to be the correct colour.

Or you could buy them direct from Honda for about $.75 each.

The rules for corrosion protective plating on fasteners have changed quite a bit in the last 30 years. Different colors may be caused by different processes. If you are really concerned about exact color matches to the original condition, you may have a problem. On the other hand, I have seen owners using hardware store collar nuts on the exhausts. I don't think it will take away from the value of the bike.

Yellow zinc is rated a bit higher than bright zinc for corrosion resistance.
Supposedly.
Ymmv.

I bought those same yellow nuts, too. I was more worried about the knurled pattern on the nut flange causing a problem with the coating on the exhaust collars. I think the original 1979 ones had "smooth" flanges.

I used my own judgement and split my project fasteners into two buckets for re-plating - one bright zinc, one yellow zinc.
Oh, and one black.

I'm not doing a showbike restoration, or I'd be in concourse judge's hell for more than just fastener sins. :lol:

If you're having plating done without concern for authenticity, try for cadmium. Better than zinc. Might be more difficult to find. Definitely better corrosion resistance.

I went with Nickel for the tank and exhaust stuff.
