CB750 K5 tank colour
« on: February 22, 2020, 09:45:03 AM »
Hi,
I’m new to the forum and was hoping to get clarification on paint colour for my year of bike, a CB750 K5, manufactured September 1974. It is currently a faded sunrise orange candy flake and from what I understand this colour was not available for the K5 model. I’ve ruled out a faded flake red which I understand is a K5 colour and can fade to an orange appearance, because the orange is still very vivid where it has not been exposed to the sun. And it is obviously not planet blue. The bike didn’t have side panels when imported from the US to the UK so no help there.

The other query I have is also with the tank. The fuel tap is on the right, but I understand it moved to the left for the K5 model. However, I read there were some K5 bikes that had the fuel tap on the right (I assume as old stock was used up).

Could it be possible this bike was supplied with a sunrise orange tank with fuel tap on the right if manufactured in September 1974 (K5) model? Has any other owners seen this?

Regards,

Andrew.

Do you know for sure it's the original tank - if it's not, the paint / fuel tap could well be wrong for the 75 model.

Back then when buying a bike you could order with the dealer previous years tank and sidecovers. Yes the earlier years had the petcock on the right and the fuel line would have to be modified.
There were no color designation in the vin to identify what color it was from the factory. If it is an actual 1975 there was only the Apricot Red and Planet Blue so choose a color you like.

also, are you sure the bike is a K5? Did you run your engine and frame numbers?

Features on the bike according ”honda750expert” and the engine (E2400346) and frame (2519523) numbers seem to place it as a K5 model.

Have no way of knowing if tank is original as no paperwork was provided with bike. In the UK, registration details identified the colour; would the Colorado plate number for this bike reveal anything if it was possible to access these records?

Good to know, that means it could be feasible the tank is original if it was possible to spec the previous years colour, but if only the earliest K5 models had the right sided petcock then I guess that would rule my tank out given the K5 was manufactured between May and Dec 74 and my bike is a Sep 74?

well, you could always order any tank or side covers for any year bike anytime you wanted, or just swap parts, so that's no proof of originality. I don't know about colorado but my Pa. registration and title for my 550 doesn't give a color.
The U.S. K2,K3, and K4 had sunrise metalflake orange as a color.
A PO swapped yours out ,it seems.

What I was saying was, just as a possible reason, the original purchaser could have had the dealer swap the tank and side covers at the time of purchase to be set up with the earlier tank and side cover color, (which had the right side petcock).
And yes your 9/74 date is a 1975 K5 that would have shipped from Japan with either the 1975 Red or the blue color.
You can still order 1975 tank and side cover paint sets from Yamamia in Japan, CMS there in the UK and maybe David Silva Spares.

First off, welcome.   Secondly, who know what has been changed on a bike that is 45 years old and has gone from Japan to U.S and then to U.K.?!

Buy a good set of sidecovers and paint them along with your tank the colour of your choice and ride off into the sunset!
