My New Project

The Corte e Cosso shock is temporary.
I will be restoring a pair of Cerianis for it as that is what the early* 1200s wore.

Where the casing covers the crank there is a shaved down area that would have had the 1000 logo embossed there.
Until the 1200 was introduced all the triples were 1000s so the casing only needed to show '1000'.
Shortly after production started the factory re-cast the casing to infill the embossed area so that the casing was generic for 1000 and 1200s.
One of the many small differences between earlier and later 1200s.
The change happened 'around' the time the update such as tank badge, Marzocchi suspension, Paioli fuel taps were implemented.
I think I have only seen one green Mirage pre-updates, but not sure if that was a retrofit by the owner or ex-factory.

I do like them shaved ......

Not me. I like my primary cases as hairy as nature allows

8) Me too, the idea of going down on something the reminds you of a polar bears twat isn?t that appealing. (puke)

Waxing off is better than stubble though, because whisker rash on ?old scar face? isn?t very appealing either.

Clem, you can tell em about the dimple.

... here are some pix of the three versions of 180? triple primary chaincases. Don't ask me if they are for sale - these are old pix and the consumption of primary chaincases is high when racing triples ...
Ciao, Gert

You missed one Gert, the early 1000 chaincase didn't have the round bulge at the bottom.

 

[Grant]

Thanks Gert, I couldn't be arsed to collate all the images.

You missed one Gert, the early 1000 chaincase didn't have the round bulge at the bottom.

Ciao, Gert

that"s the dimple,and as Pat says, not on my 3C.

 

[CLEMTOG]

and there is one more even earlier than that!

[Grant]

How does that differ?
Not including the prototype ones?

 

[Dellortoman]

that"s the dimple,and as Pat says, not on my 3C.

That's not a dimple, it's a pimple.

 

[LJ-2]

depends on looking  inside.

Finally got my hands on the shaved down primary cover.
I quickly spotted some damage but it can be laser welded and as good as new again.

Grant,
how can it break there? Tension of the primary chain to high or broken and blocked engine?
Is there any advise to avoid such a problem?

Domed nut on the adjuster bolt scraping on the ground on a corner.
Easily done.
