Alluminium cylinder kit with Nikasil plating and 200 cc capacity made by Gilardoni. The piston with 66.4 mm bore, running-in coating, two 1mm thin steel rings is supplied by Meteor.
The cylinder has four transfer ports and one additional boost port above the intake plus a one piece exhaust port.
- Port Timings
- Inlet 138°
- Main transfer ports 132°
- Secondary transfer ports 129°
- Exhaust 178°
The head has a step for centering and perfect sealing. Therefore the kit should be used with a crankshaft with 58 mm stroke.
The design of the exhaust port is made exclusively by Gilardoni for Casa Lambretta. The Nikasil coating has chamfers below and above the exhaust port, that allow the piston rings a smooth transition into the bore.
IMPORTANT:The stud spacing for the intake manifold is that of the 200 models! So you need an inlet manifold for the big block.
Conclusion:Reliable touring cylinder with a good power spread and moderate consumption.
