    Posted: 04 Feb 2018 at 18:49
hi,

I'm looking for some help / advice.....

couple of years ago i bought a 1981 Le Mans II.

it's got Lafranconis (awesome Big smile ) fitted on Tarozzi rear set brackets (awesome again - make the bike actually comfortable to ride  Big smile).

It also has Marzocchi Strada AG shocks fitted (the red ones with the air pressure reservoir).

However, these are fitted upside down, with the reservoir at the back,  i think probably because there is no space for the reservoir to be at the bottom, with the Lafranconis fitted.

My question is, does anyone know if the Marzocchis will work properly when fitted upside down?

thanks for any help anybody can give on this,

regards
Martin

I used those on my Spada and am pretty sure I had the reservoirs at the bottom and in front. Spada silencers are upswept same as LM.

Hi Mike,

Thanks for replying and the info.
I also had them on a Le Mans II first time round, way back.

The Le Mans backs then even with standard pipes meant the reservoir would only go at the bottom if fitted to the back.
On the current Le Mans the Lefranconis are so tight to the bottom shock mount that there’s only room for a standard single coil shock.

So it’s either upside down, or new shocks !!!!!

Could well be, was 30 years ago. Big smile Come to think of it probably more difficult to get the pump syringe on if fitted forward.

Found this overhaul manual -

Can't find any photos of them fitted upside down.

(Almost) all piggyback shocks are designed with the cartridge on top, it seems to make more sense as the heavier half is then "suspended weight". the Marzocchis have the logo the other way round, it's pretty mysterious, but I wouln't hesitate to try & use them cartridge up before "new shocks !!!!!" !

thanks very much for the info.
Makes a lot of sense what you say about having the weight as sprung rather than un-sprung. That was my thinking too.
Just Marzocchi being strange I guess.

Will definitely get the shocks refurbed and mount with the reservoir at the top.


cheers,
Martin

I had those sexy red shocks on my LM back in the day.
 
Stiff is the word that springs (tee hee) to mind...
 
Perhaps a pair of Konis might be a better solution, though not as sexy of course.

Hi LemansII

 I`ve seen people mounting shocks with reservoirs upside down through the years, never tried it myself though.
Found this,- showing Revival Cycles having no scruples mounting them that way either : Moto Guzzi Le Mans by Revival Cycles — Higher City Wedding Films
Shocks are "revalved" though, whatever that includes.
Try it out, see how it goes !

Ciao
                Ben

thanks guys for the info and pictures.
going to refurb the shocks, but (this might be heresy) I'm going to paint them gold to match the gold on my black and gold Coburn & Hughes LM II.
(they were already gold when I bought the bike)

Marzocchi are aftermarket so go for gold (or any other finish for that matter).

I like the Laverda grey treatment but can't be bothered changing the colour and mounting them upside down might avoid rubbing on the brake caliper.

The down side are that they will need re-valving, and in standard form, are prone to shaft seal oil seepage.

Marzocchis have never worked, either way up

hi John
thanks for the reply.
can i ask, when you say 're-valving', is that just a standard refurb / rebuild or something more specific?

hi ronza129

you could well be right. 
I'll get the Strada's refurbed, as they were original to the bike when i bought it . 
then if they don't work, I'll store them and put on some Ikons

They improved my Spada, so the stock shocks must have been REALLY bad. LOL
