High-torque, very suitable for everyday use 70cc aluminum cylinder (47mm bore) from NARAKU. This cylinder is slightly more rev-happy than the 70cc cast iron cylinder and has a much better heat dissipation thanks to the aluminum construction. The power output from a standstill allows a very good traffic light start and pleasant hill climbs. The volume remains almost at a normal level. A rich increase in power is realized even with original exhaust, which makes the cylinder a daily all-rounder. Special attention was paid here to the piston quality: The NARAKU piston is provided with a molybdenum coating. This protects the cylinder and piston especially during the break-in period. Suitable for both original exhaust systems and sports exhaust systems. Carburetor jetting must be increased slightly (approx. +7% to 10%). We recommend to use a cylinder head with combustion chamber for 70cc cylinders, like the 70cc NARAKU cylinder head. However, the cylinder can also be run with a normal cylinder head. However, then the compression ratio is higher, which the electric starter may not be able to handle.AI-translation
