Apart from the very poor choice of music :-) this K0 is very well restored, we just wonder if these lower fork are not K1 because of too intensive polishing? Something had to be found !!

Hello,
Indeed, the box was packed in the bubble much too early before the varnish was completely dry and very hard ...
You must always leave at least 10 days for a complete hardening at a temperature minimum of 20°
Yes, you can try this method recommended by Sam, but you see with the guy who did the job before doing the irreversible damage because he is the professional and he is best qualified to fix the problem and you see what he is doing can advise you and do about this problem ...

Hello 42barab
Nothing written on this subject to my knowledge ...
I noticed this little detail on two or three K0s very very late when the production of the K0 and the K1 was going to "overlap" and therefore when the carburetor bodies started to be modified seen from Production K1 ...
I don't know if I am making myself understood with the translator ...?
You will notice the same detail in the photo of the K2 carburetors and there is the same detail on the K1s .
And I don't think the Honda factory made two kinds of carburetor bodies during the official Sandcast period...
It must therefore be deduced that this model of carburetor is very very late in the production of the Diecast K0 and very close to the production of the K1 ...

Look carefully, you will find others!
For example, the plug to connect the 14 mm oil pressure gauge when normally it is a 17 mm...
But after all, everyone is free to do according to their means ...
But we are not talking about $20.000,000 on this Sandcast... but rather $50.000,000 
so at this price no excuse is allowed and especially no bad part 
Me, I call it a reconstruction but not a restoration ...

Personally, I think it's better to modify an original part when possible rather than buying a bad reproduction
of Vietnam... So yes, it is surely possible to do so provided you redo the chrome plating of the mudguard ...
And if you are convinced that your Sandcast is more authentic afterwards, then that is the only thing that matters and this perfect!

Hello John 
Go see this forum link, it will guide you I think...

All these little stories and anecdotes are very interesting to read...
Here are pictures from 1971 during a Critérium 750 race at the Circuit du Castellet near the city of Marseille in the south of France. It's my best friend who is the number 11 at the head of the race ...
He was completely crazy in competition and as much on the roads or even in the streets in the middle of the city.
I had another friend who had a Norton Commando Fastback and I must say that when we were racing on the road, he was still far behind me with my CB750, it was a K0 from April 1970 bought back next in flight from my Sandcast in March 1970 in Paris.
