ArvidW :
Laten we het erop houden dat het in ieder geval geen plug and play is. Je zit bijvoorbeeld met een 46mm slag krukas en een cilinder die ontworpen is voor 39.2mm slag.

I’ve done the modifications except for the portlowering.

I’ve milled the adaptorplate , the squish is set to 0,5mm with thinnest gasket.

I also milled topchamber…[Lees meer]

Mark Lundahl :
Nice engine….

Does everything works??

Do you know were you can buy spare parts for the engine??

This is not a running engine.

You need to lower the ports so the piston is in horisontal with the ports in bdc.

You need to buy new gaskets and screwset (about 30 euro max)

(600 euros incl)

The clutch of the vario
Is it 90 or 100mm?

90 I think

Buy Sprocatti carter , crankshaft and ignition for 250 euros.

// Sebbe

*plz dont put updates in the topic title, thx.

Then I need forkcrown for citta and I’m gonna order small things like clutchsprings , tiretubes etc.

Left to buy:
Cylinder
Delta clutch
Wingbell or R/T bell

nejc93 :
this is sporcatti albero corsa 44??

Check your pm.

Simonini crank?

Martino :
I prefer you used your older topic with the same title, 😉 but even though the the clutch rotates differently it still works.
Tonni is actually busy changing the way the segments move so they pivot the other way around.

Hmm okay , you can remove this and I’ll write in the other ?

ritze :
that crank is nog going to survive that 😛
omg but looks promissing.

do you also got plans for tuning the disk?. maybe you sould get more then one disk to tune them differently
if that is possible

greetz

Not going to survive ? It takes 18k rpm , my bb86 will do around 15k..

hansieb :
Will sprocatti also put this engine together, or is it a Ikea package ;)?

Ikea ?

It will come as loose part, I’ll put a Malossi bigbore 86cc in it.

I sent the money this tuesday so I just have to wait now.

I’ve I where you i was going to build this engine under a ciao. I’ts sicker, and we have already the sprocatti citta!
So why change from ciao to citta 😕 ???

My ciao frame was all fcked up since it has been welded between sadle and gas tank when it wasn’t straight. That’s why I bought a citta instead , I’m probably the…[Lees meer]

ArvidW :
See few posts above

I already bought 1:7:5 , Im going for 13″ wheels etc so..

ArvidW :
First axle: The force fit of the 10mm pin between fox and vespa part gave away, so no torque could be transferred any more (axle still in one piece)

Second axle: Weld between both axles gave way, screwtread between both parts broke. Axle broke in 2 parts. Clutchbell passed me at aprox 80kph :lol

Will 1:7:5 work ?

ArvidW :
I used a stock 13mm citta variomatic v-belt because I used a Fox clutch which is designed for 15mm belts (and accepts 13mm v-belts).

During the 3000km’s I had a simo07 setup, a setup of tuned piaggio parts (exept for exhaust) which reached just over 80kph, and a side-inlet DR70evo setup capable of just over 95kph. However I’m not a…

Nice exhaust!

What was your experience with Sprocatti while contacting them? Did everything work as planned?
What about guarantee?

And I’m very curious to see some pictures of the ProRace Proma exhaust 😉
IS this a good exhaust?

Oh yes, that carb. Is it a Walbro or a Tillotson?
Thanks!

ArvidW :
The minarelli axle is not a drop-in replacement. You need to combine the front halve of the minarelli axle with the vespa axle.

There are multiple way’s to do so. Multiple people at this forum did it in different way’s
– Me (http://www.vespa-ciao.nl/page.php?id=294)
– Virgil
– Herrflick
– Javad

and probably some others. My axle…

Do I need vario axis to modify to minarelli ?

Is there a roller cage in the hub for the axis that I need to replace to a bigger one that fits the minarelli axis ?

// Sebbe

Martino :
Even so it all depends on what you are looking for? I thought the Malmby meeting was only a drag strip, but i see now they also going for top speed.

I am mainly going for acceleration but it would be boring if the gearing stopped at 100km/h

Martino :
If you want to use a Minarelli clutch. You had to make your own gearing anyhow. So you also could make the choice of using a 1:6,5 ratio from what we call “bromvertanding”. But in my opinion this is somewhat to long, even for the faster engines like a Simo 2007.

I will use an engine that is a little better than the simo 07

ArvidW :
Depends how fast you want to go.

Stock simonini 2007 engine + “25kph” gearing (1:10.73) + peugeot fox clutch + citta wheels = just over 100kph. A ciao may reach 110-115kph and that is with relatively low revs compared to a fast scooter cylinder.

Can you recommend any faster gearing ? Except for malossi.

Kamelen :
Minarelli uses 39,2mm stroke , 2fast4race/Malossi bigbore 86cc has 44 stroke which there is a simonini crankshaft for , also the Team cristofolini cylinder uses 46mm stroke.

Ik heb een krukas met 44slag maar miste 3 á 4mm bovenin. Dit komt omdat de drijfstang iets te kort is.
Nu moet ik dus een puch drijfstang erin…

I will probably receive my js90 exhaust tomorrow, The citta chassie is being sent tomorrow I think.

My sprocattiparts will be sent in the beginning of january.

That’s about it for now.

very nice men !

my neigtbour drives with 70 cc R/T cilinder on his aerox, its very fast faster then the malossi 7t.

i hope to see more from this project 😉

Whats the rest of his setup ? 😛

I guess vforce3 , 28mm R/T PWK , S6/yasuni/roost R/T or c30 ? Stage6 spacer ? HPC crank ?

Tell me more…

I also sold my R/T, Im going for 2fast or bb86, we’ll see.

ritze :
if you pull that together you`ll be fine 😉
uuhm, just thinking with you, what is your goal speed?

that cilinder should be running @ 12.000+ rpm, so that in combination with vario 1/10.5 wil give a speed of around 100 kmph
i drove with that vario setup 10.120 rpm @ 88 km/h, maybe you can use this information

by the way, you make…

it will save you a lot of explaining efforts

Well , Swedish and english doesn’t match 🙂

very insane setup youre going for,
but is 44mm crank not too much?

i always thought that mina engine`s have got like a 39/40mm stroke length

That’s right, they do have 39,2mm.

I really don’t want to explain it now xD Did it like 20 times on other forums 😛

I received my 24mm pwk carb, my wheels is probably coming tomorrow, I will get a ajustable “sproier” for my pwk this weekend, I reserved an Ivanobell and I bought an r6 brakecaliper which probably is sent tomorrow and received @ Friday.
