Stage 6 R/T 70 LC cylinder kit Yamaha/Minarelli

Insanity on the end of a conrod - a revolution in the 70cc class of scooter cylinders has been started by Stage 6 with this modular racing cylinder kit. With a host of world records under its belt this cylinder is now released for use by the lucky few. This high performance scooter engine kit is a modular type and comes with: separate cylinder base with high accuracy stud mount multi-fastener, port matched exhaust outlet to weld your pipe to modular head with optimised combustion chamber anodised high volume head cap for max cooling owner's manual with full specs including port timings nicasil lined alloy cylinder with particular cooling passages around high stress areas multi stud arrangement to mate cylinder and the above base Other notes: Highly recommended for use with adjustable timing to enjoy what this cylinder is capable of. Must be used with racing crankshaft (we strongly recommend longer conrod), matched racing exhaust, intake, big carb, liquid cooling system. This uses a 12mm gudgeon pin so ensure you have the correct crankshaft. Additionally the crankcase has to be modified to match the modular cylinder base's larger size. (56.7mm internal diameter to a depth of 10mm, more matching possible if desired). Feel free to consult us on the best combination of parts to really lay down some pain on the competition. When set up properly this cylinder delivers 26bhp and 12Nm torque To suit scooters with Yamaha / Minarelli type engines (note fitment info above) including: Yamaha Jog, Vino, BW's, Aerox (all horizontal 2 stroke 50cc) Adly SF-50 (Silver Fox) Adly GTC-50 (Gatecrasher) Adly GTA-50 Aprilia SR etc (with Minarelli engine) plus other Taiwanese etc scooters using the same type of engine
