 Product Description

buying-2-discount-300pxl-.png● 160CC CYLINDER KIT, HIGH COMPRESSION FOR STD HEAD (eSP+ 125CC/150/160 ENGINES) (12100-K0S-V60)

● This specific 60MM cylinder kit has been developed to produce a higher compression ratio with the flat piston design compared to stock, and this specific set has been worked out to be used with the stock STD 17/20mm 125/160cc valves.

● If you install this YUMINASHI 60mm cylinder kit (12100-K0S-V60) on a 125 engine, then your are hitting 2 birds with 1 stone, because you are working a solution out for the lower compression of the 125 engines (11.5:1 to be exact for the 125, and this is 12:1 with the Honda 60mm piston installed on the 160 engines), so the compression become higher, and you get a very reliable 156.86cc engine instead of 125cc.

(Your valves in the 125cc cylinder head are prepared for the 160cc piston, because both the 125cc and 160cc eSP+ engines are using the same 17/20mm valves).

● If you have a "150"/160 4V engine, then the flat higher compression piston in the set has also the possibility to produce more power compared to the stock 160 dish type piston, so both the 125 and the 150/160 4V engines have a benefit with installing this kit... 

※ Recommend to be installed with the YUMINASHI ST238 SPORTS TOURING CAMSHAFT! (LINK)
※ Engine will make best acceleration and top speed with the 30mm manifold and throttle body set installed.

info-icon-25pxl-.png Torque Spec for the cylinder head nuts are: Torque 27 N m (2.8 kgf m, 20 lbf ft)

 

● PISTON DETAILS:

● The piston you get in the 160cc YUMINASHI high compression kit is not only a higher then the stock 160 piston, but also a lighter piston compared to stock, where the valve pockets are prepared to run a high lift performance 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 erector-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.

※ The valves of the 160cc and 125cc head are the same size, there is no difference in valve size between the 125 and 160 4V head.

※ We recommend to install the 140cc B-type 8-holes injector (LINK) if your stock/original engine is a 125cc in combination with this 160cc cylinder kit.
※ If your engine is stock/original a 160cc engine, then you can use the original injector, no need to install another one...
