Restoration by Puccio from Tuscany

[kp]

Great post and a novel way of recording a restoration. A picture tells a 1000 words but a video tells a million. I loved it 
As for Sirius in Canada, I've been buying parts from them since I don't know when and all their products are good and service is great. Deal with them direct rather than ebay and you will save on postage  and maybe cost of the parts. I don't see why their pistons would be any different to anyone else. I would use them. KP

Hi to all, friends.

I need information about balancing of crankshaft.
During the engine disassembly, I seen the difformity of connecting rods.
In the picture You can see the number printed on side.

I don't understand why the first is different

So, I want to balance the cranckshaft but I don't understand if during the operations is necessary disassembly the  connecting rods.

The connecting rods must have the same weight?

How did the honda?

Sorry, but occasionally I don't find the correct translation.

Hi Wayne and thanks for fast reply.

I prefer to check every part before continuing.

The price is ok, 40$ for white and gold galvanizing.

Hi Friends,
Great news, during a last motor-show in a city, near my home, I buyed this book.....

https://picasaweb.google.com/puccio70/OwnerSManualCb750K0?authuser=0&authkey=Gv1sRgCNKFy_fipLXRFQ&feat=directlink

Is very beautiful and printed in the 1969.
The price? After a long battle I won for 79,00 $
But the language is in English......Ok, so I can also study the language    

Happy happy happy

Hi friends,
Soon,  I will paint the gold line on the tank.
I seen on internet the special striper, for paint the black lines.

I matched the size with my stripes, but I'm not sure.

I would buy this item, but I dont know the correct size of black lines.

Please can You help me? Can You check the size on Your tank and show me the correct model?

Many thanks
