Cylinder kit 63cc | NARAKU

Product description

For those who do not want to go radical with performance tuning such as 47mm or 51mm, but fancy a little more grunt, there is a 63cc cylinder kit with noticeably better drive than the 50cc original This cylinder kit will iron out holes in the drive as well as on inclines. Kit includes cylinder, piston, piston ring set, oil scraper rings, gudgeon pin, gaskets and circlips The piston has 2 CNC-machined oil grooves to stabilise the oil coverage Lubrication of the gudgeon pin is taken straight out of motorsport and is aided by additional oil holes and grooves Also suitable for other scooters with new SYM 4-stroke engines (bore/stroke: 37x46mm) e.g.: SYM Mio 50, SYM Fiddle II 50, SYM Orbit II 50, SYM Jet4 SYM Allo 50, SYM Cello 50, SYM Symphony 50, Peugeot Vivacity 4-stroke, Peugeot Speedfight 3 4-stroke
