Naraku 70cc Sport 1E40QMB AC 2-stroke cylinder kit

The Naraku 70cc sport kit are a high quality cylinder kit suitable for everyday use while providing great increase in performance. The machining is very good and the layout of the ports is very promising.
A top quality kit from the Taiwanese manufacturer Naraku.
An increase in bhp and low end torque is to be expected. 6 hp on a air cooled engines, however it the torque what counts and this cylinder concentrates on increase torque so expect a good jump in off the line performance. A perfect choice to replace a worn cylinder, excellent quality, great performance whilst maintaining reliability.

This kit is designed to be used with the original cylinder head but larger head is available. We would recommend you also increase the main jet by approx. 7-10%.

Please be aware that some scooters that is listed may have used a 10mm piston pin so we fully recommend you check this prior to purchase. If you do need a 10mm piston pin then you will in addition need to purchase part number NK100.99 which you can search for in our shop.
