Yeah that looks like a 500 seat pan, doesn't look like the foam and cover are on though. Are they seperate or did you find just the pan?

After reading DLHoulton  http://forums.sohc4.net/index.php?topic=137510.msg1551239#msg1551239. I was given the confidence "to have a go ya mug" as they say in the classics.

I've started spraying 2 coats on my head light after 3 - 4 hours filling, then sanding and then more sanding, and then more sanding, and then more sanding, you get the picture.

From the start





After 2 coats





Next more sanding, then 3 - 4 coats of clear.

Very pleased after 2 coats,


Regards

Valves lapped, next head and barrels are going on a machine (not sure what it's called) to ensure perfect matched surfaces.



Head painted and ready for assembly.

Milling and decking is the machining process you referred to. Typically performed on a "Mill".

Looks great by the way, Mick!

I just read this thread from start to finish, it makes me very happy.
I have a severely trashed and thrashed 500 which is going to need similar treatment!
1973 CB500 K2 - needs a whoooole lot of work.

The head and barrels are being put on a Linishing Machine and being linished.
Wikipedia states Ianishing is -
Linish is an engineering term that refers to the process of using grinding or belt sanding techniques to improve the flatness of a surface.

Question - I've bought a generic pack of CB500 gaskets, it includes every O ring and seal needed for the engine does anyone have a comment good or bad about these? Any assistance would be appreciated.

the gaskets will be fine mostly except for those formed o ring ones are sometimes too thin and don't crush and seal properly,with the rubber gaskets in the well cleaned groove they should sit proud about 1/3 of their thickness?some might be almost flush which isn't enough.

Thanks Dave I'll pay particular attention to your comments and check out the o rings for thickness.

Finished stripping paint off the tank and right side cover (I'm still looking for a left side cover).



Cover with adhesive applied ready for paint, get Candy Gold mixed tomorrow and into 3 rattle cans.

I have the red packaged seals. No update on them as the engine is waiting for the frame to return.

I'm thinking of painting the 500 in original Candy Gold.

To the gurus -

Q. Did Candy Gold have any metal flake in it? I can't remember.

Thanks in advance.

Candy gold was a 3 pack paint
(1) silver base

(2) colour tinted see through paint--more you put on darker it gets

(3) Laquer

BryanJ thanks mate, but I've changed my mind and am going old school with a candy apple red metal flake.

So much for the original CB500 colour, I never did like Honda's colours all that much. I had a red Honda 750 '74 model.

I wanted the 500 to really pop and I trust it will.

I've started on the right side cover (the only side I have for the moment), back to bare plastic and applied 2 coats of adhesive and the a coat of gold as a base for the red.

Then a mix of red flake and 2 pack clear will be applied when I spray the top coats.
