Hi Martino! My friend how you doing?
Thanks for your advice, but it seems difficult to find it also in italy, and I remembered you guys! This great community.
I realized my profile is brand new,so I will update it in while.
Thaks a lot also to you Crullie 😉 but yep…I need it standard, at least could be 44 stroke, but standard…[Lees meer]

Hi Javad, sorry for the breakdown.
You broke it, in the same way I did, and is used to .

I think the problem is the key hole.
Probably it’s due to the little movements that the key does into the hole, and this can cause a little crack.
After several runs, the crack develops into the shaft, and than brake it down.

otherwise , if you can find a Simo side inlet, you can combine it with the standard half cranckcase , so that you can use also a 1313 dell’orto carburetor.
In my opinion this combination should be the best.
The only difficulties is that you have to set up the two carburetors very well, in order to get the best throttel response.

Hi Speed!
Nice to see that you still have my cylinder.
If I’ve understood a bit of dutch, I can say that mine was
one of the last simonini’s stock.
Infact I remember that the surface coating is differnt from the first series.
If I don’t mistake the first one where chromed instead of nikasil one.

The dark colour is also due to the special…[Lees meer]

You mean jet size 50 ? With this setup:

41mm DR
original carters
original crank shaft
1212 carb opened up till to 13mm or something more.
giannelli mega or leovince exhaust
Variomatic transmission made of polini utah and original clutch.
electronic ignition with lightened flywheel.

This needs like a 64-66…

Now I gotta a problem:boos
Today after several attempts, I’ve started the engine.
I had mounted a gigleur N°50 on the 1212 dell’orto.
The inlet manifold has been enlarged up to 13mm, but not worked according to the flux.
The fact is…that the engine always starts at the first try, but I can’t accelerate
because it becomes to reduce the…[Lees meer]

I’ve modified the brake plate like the old racing motorbike, with an air intake.

Javad :
You know what happened to your last flywheel, right?
Because you milled the top part, the wheel gets very thin, and with the holes it gets realy weak.
Also because it is still a heavy flywheel with 1,1 kg there will be a lot of force on the little parts that are left on the top part.

There is a big chance this will happen:…
