The GORI 200cc 'Sport' tuning cylinder kit is designed for use with the Lambretta 125-175cc smallblock motors, in combination with crankshafts that possess a 107mm con rod and 58mm stroke. Features including its solid overall design, a high end bore finishing, completely redesigned transfer port architecture and inlet and outlet ports ensure a noticeable but measured increase in power output, when compared to standard motor set ups. Although the use of this cylinder kit in combination with a standard sized carburettor is possible, Giancarlo Gori himself recommends the inclusion of a large diameter carburettor to exploit its true potential. Alongside the cast iron cylinder the kit includes a re-profiled aluminium cylinder head, a specially produced 'Meteor' piston with three piston rings, a freshly conceived inlet manifold, a stiffer set of clutch springs and all the necessary gaskets.
Cast iron cylinder / Ø66mm bore / 2 transfer ports / 3 piston rings
Redesigned cast iron cylinder with 2 transfer ports, piston includes 3 piston rings, kit includes aluminium cylinder head, inlet manifold, stiffer clutch springs, gaskets.
Conclusion: An optimal compromise between an improved overall performance and increased reliability.
SIP-TIP: When using this kit in your motors set up we recommend its combination with the 'Sport' exhaust system (#22084000), also produced by GORI. The gear ratios will also require modification and should be adjusted to suit the purpose of the scooters use and owners riding style.
