This is the Airsal aluminum race cylinder. This is the ultimate marriage of price and performance. The piston is of single ring design, to eliminate friction and drag. The properties of aluminum allow for faster cooling and longer cylinder life over cast iron.
It is cast from an aircraft quailty T-6 aluminum, then the cylinder is coated with a Nikasil lining. Nikasil coating is a nickel and silicon carbide matrix and is very hard, but it is comparatively ductile. Dispersed through the nickel are particles of silicon carbide less than 4 microns in size. Beside providing a very long wearing surface for the piston and rings, the silicon carbide particles also contribute to longer engine life by ensuring good cylinder lubrication.
It will produce increased torque when installed with the stock pipe (alt. Stage 1).
When installed with a Tecnigas pipe, Arreche carb and Tecnomoto variator, (Stage 2 kit) (http://www.provoscooter.com/shop/product_info.php?cPath=34&products_id=98) it has a 55-60mph top speed and break-neck acceleration. If installed with an expansion chamber pipe, you must upgrade the carb to ensure reliability.
NOTE: If you have a 2004 Vento, you may need a 12mm diameter wrist pin, which does not come with this kit by default. You will need to use the menu below to add it to your order. The added cost is regretable, but unavoidable as cylinder kits only come with 10mm wrist pins. Please verify this fact before you order to avoid being without your scooter while you order the piston kit (the only way to check is to pull the cylinder and measure the piston write pin, but this is not a difficult task and should only take about an hour or so, see the howto (http://www.provoscooter.com/shop/howto70cc.php)).
