High-torque, very suitable for everyday use 70cc cylinder kit from NARAKU. This cylinder kit is not designed for high engine speeds, its strengths lie in the lower speed range. Already shortly above idle speed follows a constant and very good acceleration, without loading the engine with unnecessarily high engine speeds.
The power delivery from a standstill enables very good traffic light starts and 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 original exhaust systems and sports exhaust systems. Carburetor jetting must be increased slightly (approx. +7% to 10%).
We also recommend the use of a cylinder head with combustion chamber for 70cc cylinders, such as the 70cc Naraku cylinder head. However, the cylinder can also be run with a normal cylinder head. However, this will result in a higher compression ratio that the electric starter may not be able to handle.AI-translation
