● This 150 STD ESP HEAD & DOME PISTON SET comes with the 60mm 13mm pin high compression piston in the box to upgrade your eSP 125cc engine in to a 164cc high performance engine with big 29/23mm valves 150 head.
The 150 STD Head comes complete with the larger valves, and special double reinforced valve springs with special retainers installed and a 3pcs 60mm copper gasket set mentioned for the high compression 60mm dome piston.
The 150 STD Head accept your stock 125cc eSP rockers and camshaft, but we do recommend rockers with larger rollers if you are using a high performance, high lift camshaft. The details from the larger roller rockers can be found over here.
The 60mm 164cc Dome piston is prepared for the larger 150 STD Head with 29/23mm valves.
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 extermely 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.
■ This specific set with the included STD150 Head is mentioned for all eSP 125cc engines and can not be installed on the first generation PCX125.
■ The dome piston can be installed in to a stock PCX150 cylinder if you bore the cylinder up to 60.04mm (Need to be installed with a copper gasket, just keep in mind that a stock cylinder has a higher chance on a leaking head gasket compared to this Yuminashi Flat Deck cylinder).
