Aluminium topplock med förstorad förbränningskammare tillverkad speciellt för 70cc cylinder kit Naraku Minarelli AC (NK100.31) och CPI & Keeway cylinder (NK101.47). Toppen passar även andra 70cc Minarelli cylindrar med 47mm borrning.
When using a Chinese engine:
This Naraku cylinder head requires the use of a short thread spark plug (NGK type H means short thread) such as BR8HSA, BR8HS. Attention: some Chinese engine manufacturers like Keeway, CPI etc. use from the Euro 2 models year 2003- an original spark plug type E with long thread like e.g. BR7ES. Those spark plugs do not fit here!
