 Product Description

buying-2-discount-300pxl-.png● 160CC / 60MM (FOR 22/19MM VALVES GT220 4V HEAD) FLAT HIGH LIFT, HIGH COMP. PISTON SET (14MM PIN) (eSP+ 125CC/150CC/160CC) (13102-K0S-260A)

● This YUMINASHI 60mm high compression piston set is mentioned to be installed on a 60mm cylinder with the 22/19mm big valves GT220 cylinder head.

● You get a well balanced lighter piston with a higher compression ratio and larger valve pockets in the piston to install the larger valves GT220 Head (LINK), which is perfectly fine to be installed with the YUMINASHI SPORTS TOURING 238 camshaft...

● The hard chromium plating layered (Cr) piston rings which come with the set are produced by very strict Japanese standards and has excellent characteristics which combine the original properties of chromium metal with the advantages of erectro-deposits!

The main benefits from the chrominum plating layered piston rings are extremely high hardness of HmV (Micro Vickers), 800 to 1100 (cf. gray cast iron 220 to 270), high melting point of approx. 1800°C (cf. cast iron 1200°C), good thermal conductivity and corrosion resistance, a low friction factor and excellent wear resistance, such features are very effective in preventing piston ring wear.

● The enlightened piston is made from A-grade materials and the piston skirts come with a molybdenum coating. The Anti-detonation grooves on the top ringland provide several advantages, which include further atomization of the combustion charge to prevent damage to the piston and ring caused by pre-ignition. These grooves also prevent carbon build up on the ring land which can cause the compression ring to stick in the ring groove.

The pressure seal groove will prevent gas build up below the top compression ring; these gases can cause the ring to lift from the ring groove. Unseating of the ring will result in compression losses and lower performance.

※ If you are upgrading from a 125cc engine, then we recommend to install a 140cc/min 8-holes injector (LINK), if you are upgrading your 160cc 4V engine, then you don't need to install another injector, the stock injector is large enough to run this piston.

※ Recommended to be installed with YUMINASHI SPORTS TOURING Camshaft ST238 (14100-K0S-238)

※ 60MM Cylinder Head Gasket available with this LINK.
