Hi folks. I am located in south east Pa. & I own a 1967 CA77 Dream (red). This bike was my Dad's bike. It was a Shriner's parade bike before my Dad bought it (in the early 70's). about 15 years ago I got it back still titled in my Dad's name. The guy I bought it off of was the same guy my Dad sold it to. He took it apart to rebuild it (not sure why It was a very clean bike). So it was in boxes & large pieces when I got it back. I started cleaning up parts & buying parts for it back then but it has been on hold for the last 10 years or more. So I think I have everything I need to assemble the bottom end. I have been getting reacquainted with it & taking inventory of hardware to at least assemble the bottom end. So I sent lots of hardware & brackets etc. out for zinc plating back then but I missed some of the engine hardware. I am replating that stuff at home last few days when I can. I am trying to keep it stock with NOS Honda parts. I am also trying to use original hardware where I can. (it's all in great shape. One question I have is should I reuse the washers or get reproduction replacements. I'm not sure if it were judged if the original washers (replated but indented from nuts) or cleaner (straighter) replacements would be better. I have 8 acorn nuts , 6 sealing washers (steel) & 2 copper sealing washers for the head. I also have 6 8mm nuts & 2 acorn nuts from the bottom end. I have five thin 8mm flat washers & 4 thick 8mm washers. What washers were used on the bottom end 8mm case nuts? Were they all thin or thick or a combination. Where were the two acorn nuts used on the bottom end cases? Thanks in advance .....I'm sure I'll have many more questions. (edit) I just found the answer to where the acorn nuts go & that I should use new washers according to Bill Silver's engine repair guide. Still not sure where the 4 thick 8mm washers are from. Anyone have any Idea where they are from or want to shed some wisdom upon me?

Just for clarification, you intend to make this into a 100pt restoration to be perfectly correct to original specs?

If so for show purposes and AMCA judging I guess I can understand your quest.

If you just want a nice clean rider, I'd not worry so much about washers being perfect. I'd not do an allen head conversion but would not sweat details like the washers so much.

Just curious what your end goal is.

Also, not sure if original things were cad plated vs zinc plating. That would be a hit on you for a 100pt resto. But I'd zinc plate myself as it's 'good enough'.

Honda used zinc plating with either clear (silver) or yellow (gold) passivation. Both were used and they were't always consistent. I have otherwise identical NOS carbs with both types of passivation.

Thanks for the reply guys. Irutt, every bike I've owned has been customized with aftermarket parts. This bike was my Dad's. I am going to build this back as near perfect as I can & show it a few years. I then plan on riding it occasionally. This bike is a great starting point due to it's good condition. I am pretty sure that the hardware was clear zinc & the spoke nipples were gold zinc. Either way...the plating thats been done looks perfect. You guys have any idea where the 4 thick washers are used. (thicker than the head sealing washers but with same I.D & O.D )
