The Polini Aluminum 80ccm cylinder kit is quite powerful cylinder kit, thanks to its three-part exhaust port and the high-flush flushing channels. The effect is up to the level of Malossi MHR and the like. cylinder kits, so there is definitely power for all the money. As the name suggests, the cylinder is made of aluminum and inside the cylinder passage is treated with a hard chrome / nicasil coating. To achieve full effect of the kit, it is recommended to use i.a. larger carburetor as well as exhaust. A long-threaded spark plug must be used for this cylinder. The kit is delivered incl. gaskets, piston rings, etc., but without the outer cylinder head as the original must be used.
