The 2EXTREME sports cylinder is a 70cc cylinder made of cast iron at an affordable price. The cylinder kit offers an excellent combination of performance and durability and belongs to the top class among cast iron cylinders. The large overflow and wide exhaust already provide the original exhaust and carburetor for strong torque and amazing top speed. Sport cylinder ideal for everyday use, where an ideal adjustment of engine power values from 8 to 10 hp can be achieved without problems.
The kit comes with all the small parts needed like gasket set, piston rings, piston clips, etc. The supplied cylinder head also requires a short thread spark plug with an M14 thread.
The kit can work with the original carburetor if the main jet is increased by about 7-10%. However, we recommend using a 17.5mm carburetor to increase internal cooling and thus durability as well as performance.
Note:
The cylinder requires a short thread spark plug. We recommend a B8HS or B9HS / for vehicles with tachometer, BR8HS or BR9HS.
