Quattrini M210 Cylinder Kit for Small Block Lambrettas – I009
£649.99
Max Quattrini 210cc cylinder kit for the small engine block of Lambretta 125-150cc LI/SX/GP/DL models…The Quattrini cylinder has a special feature: a reed valve inlet that positions the carburettor on the left side of the Lambretta frame (the normal side). Compared to the original position, the carburettor is angled forward in the direction of travel. That would make it difficult, though not impossible to use the standard airbox.
To be able to use the largest possible displacement, the cylinder does not have a spigot base that slots into the engine block. This technique allows a larger piston than usual to be used. With Ø68mm diameter this results in a displacement of 210cc with the standard stroke of 58mm (60mm stroke =218cc) . The kit has been designed to use a TV length conrod, 116mm, with 58 x 116 being the normal crankshaft for the kit. The long conrod improves the smoothness of running and ensures that the piston is positioned higher to prevent it from running out of the cylinder and tilting.
Bore: 68mm
Stroke: 58mm
Conrod length: 116mm
Inlet system: Reed valve (carburettor on the left side / flywheel side)
Carburettor connection width is suitable for e.g. Dell’Orto PHBH/VHST, Mikuni TMX27/30 & PWK/Keihin type carbs 28/30mm.
piston: flat top (bolt= Ø16mm, compression height=30mm)
control angle: outlet= 180°, overflow= 123°
exhaust flange: Quattrini (similar to TS1 but different angle so needs a special exhaust)
exhaust flange hole bolt pattern: 65mm (2x M8)
exhaust flange Connection: Oval with flattened lower edge, at the widest point 42mm wide
The cylinder layout is, typical for Quattrini, quite conventionally constructed and has large flushing surfaces with a large rectangular outlet window (65%). The reed valve inlet also functions as a direct inlet to the transfer ports, the piston top is flat. The overflow ports at the cylinder base are designed to fit the standard engine block. However, they have enough flesh to enlarge the overflow channels on welded-on engine housings considerably.
The exhaust flange is conventionally fastened with two stud bolts (8mm instead of the normal 7mm).
With control angles of 123°/180° the Quattrini offers optimal conditions for a powerful sport tour with Clubman exhaust, but also already allows the use of resonance exhaust systems.
Current choices of exhausts are the Ron Moss Avanti box pipes, the BGM box pipe and the CST tour and fast road exhausts.
