  • The new NARAKU V.2 cylinder kit series delivers an even more powerful and refined product.
  • Since the 4-stroke cylinder is essentially just a bore, technical improvements have been focused on the piston and the compression ratio.
  • The piston incorporates two additional CNC-machined oil grooves in the skirt, designed to retain engine oil to lubricate the cylinder and optimize performance under extreme conditions.
  • A molybdenum coating eases the break-in period, a crucial step for the kit's lifespan and efficiency.
  • Two oil reservoirs and a groove at each bearing point ensure optimal lubrication of the piston pin.
  • The compression ratio has been specially calibrated to meet the demands of daily use.
  • Naraku quality and excellent power delivery complete the features of this cylinder kit.
  • The kit can run with the stock carburetor; however, it is recommended to replace the main jet for optimal tuning.
  • All parts required for installation are included with the kit.
  • For SYM scooters, this kit is compatible only with the GY6 139QMB engine and is not suitable for XS1P139QMB, AV05W, AW05W engines nor for SYM Symply 2 models.
