French Sandcasts / A French Sandcast in series 15000 !

« on: April 25, 2023, 01:48:37 pm »

Hello for all,
I have just discovered that there were also 15000 series, this is the first French Sandcast discovered in the 15000 series, this is the engine number E-1015525.
We knew that there were 14000 and 17000 series but to discover that there were also 15000 series is really exceptional!
this engine was used in competition, and this explains why the crankshaft was cut and you will also notice that it has its famous 9/10 clutch cover with the tenth hole not drilled like the 14000 and 17000 series, and let's not forget that E-1007414 also had this same cover 9/10 !

Links to Auctions and Classifieds / Sand-casting or not really sand-casting? The question is asked ...

« on: March 26, 2021, 07:28:46 am »

I just came across this article ...

https://www.kb-style.fr/dossiers/honda-cb-750-k0-sandcast/honda-cb-750-k0-sandcast-history-and-specifications/

- The first 7414 machines from 1000001 to 1007414 are commonly referred to as CB750 Sandcast.
They are recognizable by their crankcases with a rough and coarse finish.
These housings are molded in a very slow dry process, by gravity.
To say that they are "sand-casting" is therefore a misnomer.

This guy seems to know what he is talking about and he says he took some information on the forum ... Have you already mentioned this subject of molding here?
Afterwards, it is very easy to pump informations that you have not found by yourself, even to draw your own conclusions in a article ...
I don't know anything about foundry ... Who can shed some light on this?

Fuel (gas - petrol) Tanks, Side Covers and Air Box / Carburators with seat 2.0 ?

« on: February 28, 2021, 08:12:15 am »

I just saw that I had a set of carbs with seats with the 2.0 keihin mark and my other carbs have the seats with the 2.5 mark? However I did not find a different reference has 16125-235-004 even on the carbs of K1?
Obviously the hole on 2.0 is 2 mm and the one on 2.5 is 2.5 mm.

Which basic model does the reference 235 initially correspond to?
Who would have information about these 2.0 seats?

Parts For Sale / Duck tail seat 17 holes Sandcast K0

« on: July 05, 2019, 07:07:10 am »

Duck tail seat Sandcast or K0 100% original in very good condition and has nothing to do with the wrecks that we see on sale often EBay ...

Look at the photos, the Honda Logo on the back has some erasing traces, and two small cuts on the corner on each side underneath and they are circled in red on the photo of the seat bottom.

The front of the seat to the gas tank has no cuts or tears, the red and yellow foam still has a good hold and does not disintegrate.

The top seat is in very good condition with no rips or cuts, and the padded squares have a very good relief,
and this detail is very important on a Sandcast seat.

You will buy what you see...

700 euros + shipping cost

You will notice that in the first picture the protective rubber goes to the bottom of the cell, compared to the one we usually see which has a protective rubber only on the top element, like the photo 4 ?

On the first Parts List there is no rubber protection in the drawing, but it appears in the drawing on the part list of the K1, but it is curiously not referenced ?

Engine Mechanical / The meaning of the connecting rods on the crankshaft !!

« on: April 15, 2019, 05:01:20 am »

Hi everybody,

Who can confirm me the meaning of the connecting rods on the crankshaft, in principle it is the notch of the pad directed towards the exhaust, this important detail is not mentioned in the Honda Workshop Manual, and in addition on the drawing Parts List, the connecting rods have the notch directed towards the admission which for me is an error...

With my thanks
