Description

A whopping 200cc is offered by Max Quattrini for classic Vespa models such as V50, 50N, SS90, PV125, ET3, PK S, PK XL etc. With the parts available separately, a fuselage engine kit consisting of:

Cylinder (7676558)

Crankshaft (7676557)

Engine case (7676556)

can

be assembled

This not only breaks the frame of the so far usual displacement classes which were installed in these vehicles, but stands despite enormous displacement and power increase conceptionally as well as technically on extremely solid legs

...

As basis a completely again conceived engine housing serves which is poured from a high-strength alloy. This now finally offers space for a much wider and therefore enormously stable crankshaft with an incredible 56.5mm stroke (series PV125 is 51mm stroke). In conjunction with a 116mm connecting rod is so a very solid basis for the powerful 200cc cylinder from the house Quattrini created. This was deliberately designed so that he already develops at low speeds an enormous thrust and out of the box yet over 30HP and 30NM! Thus, the wide-stepped series gearbox can continue to be used without any problems. Gear connection problems are excluded due to the very wide and hefty power band

diaphragm, 4flaps, material thickness 0,5mm

The cylinder has a diaphragm inlet, so the diaphragm inlet already provided in the engine case, but still cast, is not needed. The crankcase of the 200cc engine case now uses larger dimensioned bearings of the category 6205. Since the crankshaft seal of the drive side now sits outside the crankcase, screwing the primary pinion no longer secures the shaft against shifting. It is therefore necessary to use a guided bearing on at least one side. We offer two high-quality solutions for this

6205 TN9 C3 fixed bearing with polyamide cage
6205 MA C3 locating bearing with brass cage

Special features:

No stock ignition

usable

With original gearbox usable

Cylinder cooling cover must be modified

Installable in all Smallframe frames possible (except automatic models)

We recommend a Keihin PWK33 or PWK35 carburetor matching the intake manifold. Alternatively, Max Quattrini recommends a Dell'Orto VHST26 carburetor (jetting: HD: 135-138, ND: 35-38, mixing tube: HE270, needle: D36, slide 50)
In order to enjoy the powerful torque permanently, a Hartz4 clutch including clutch cover of the PK XL2 models should be used. As gear ratio the long primary reduction of the 125cc models can be used without problems (27/69 = 2.56). Spark plug NGK B9EG. Tires: 3.50-10. Setting Vespatronic 25° at 1500rpm.
The engine case does not use sealing paper. It is sealed with a liquid sealant such as Loctite 510 or Normfest Plastomar. Tightening torque of cap screws 18-20Nm (M8). Tightening torque of housing screws 8-10Nm (M6). Gear oil quantity: 500ml mineral monograde oil (e.g. Runge SAE30). Mixing ratio oil: 4% (1:25)

We expressly point out that the kit as such is coordinated with each other during assembly, however, a knowledgeable hand and further adjustment work are necessary, depending on the other components used and the respective base vehicle

Points on the assembly should be given attention:

Adjust cylinder cover

Distance wheel/tire combination to exhaust

Distance

shock absorber to mounting screw shift fork

Distance

shock absorber to exhaust manifold

Distance

side hood closer to cooling hood
