Preview: Cylinder kit -QUATTRINI M200 (for use with Quattrini Enginecasing C200)- Vespa V50, PV125, ET3, PK50, PK80, PK125

Description

Max Quattrini offers full 200ccm for the classic Vespas like V50, 50N, SS90, PV125, ET3, PK S, PK XL etc. With the separately available parts a fuselage engine kit can be assembled, consisting of:

cylinder (7676558)

crankshaft (7676557)

engine case (7676556)

exhaust (7676559)

This is not only beyond the scope of the previously common cubic capacity classes that have been installed in these vehicles, but despite the enormous cubic capacity and performance increase, it is conceptually and technically on extremely solid ground...

The basis is a completely new engine housing design which is cast from a high-strength alloy. This now finally offers space for a much wider and thus also enormously stable crankshaft with no less than 56.5mm stroke (series PV125 is 51mm stroke). In combination with a 116mm connecting rod this creates a very solid basis for the powerful 200cc cylinder from Quattrini. This cylinder was deliberately designed so that it develops an enormous thrust even at low rpm and still develops more than 30hp and 30NM out of the box! So the wide ranged serial gearbox can be used further on without any problems. Gear connection problems are impossible due to the very wide and solid power band...

CYLINDER:

displacement: 200cc

bore: Ø67mm

stroke: 56,5mm

outlet stud distance: 66mm (M8)

Piston Wössner 41613-1 (Ø66.93mm)

Lobe clearance 0.07mm

Piston rings Wössner RSB6700

Clip CW16 (C-type, 16x1)

Spring plug long thread

Bolts cylinder base: M8x55 hexagon socket

screws cylinder head: M6x30 hexagon socket

screws intake manifold: M6x25 hexagon socket

gasket cylinder base: 1x 0,35mm

gasket cylinder head: no

channel height main outlet 35,3mm

channel height ÜS 47mm

cylinder head immerses: 1mm

intake port:

sucker outside Ø42mm, inside Ø35mm

diaphragm, 4 valves, material thickness 0,5mm

the cylinder has a diaphragm inlet, the diaphragm inlet already provided in the engine housing but still casted is not needed.

Special features:

Cylinder cooling cover must be modified

Installation in all small frame frames possible (except automatic models)

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

We would like to point out that the kit as such is matched to each other but during assembly a skilled hand and further adjustments are necessary, depending on the other components used and the respective base vehicle.

points to which attention should be paid during assembly:

adjust cylinder hood
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
frame cut-out intake manifold if necessary. extend if necessary.
