● 164CC BORE-UP FLAT DECK CYLINDER KIT (13MM PIN) (eSP 125cc Engines 2012 - 2021) FOR 2-VALVE 150 HEAD

● The 164cc Flat Deck Big Bore Kit is pure racing DNA from the YUMINASHI PRO-SERIES which comes with a dome piston prepared for the 60mm 150 STD head 29/22mm valves!

The Flat Deck Light Bore Kit with larger water/coolant capacity has been developed by the Yuminashi R&D to have a cooler running engine which is able to run higher compression ratios without the fear of blowing head gaskets and to push the envelope on the durability and reliability side as much as possible with installing a entirely new very hard cylinder sleeve which comes directly from the Yuminashi racing series engines to avoid ovalisation, oil leaks and compression loss!...

The hard chromium plating layered (Cr) piston rings which are produced by very strict Japanese standards 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 valve pockets in the piston are prepared to run with 29/23mm valves from the double valve springs Yuminashi 150 STD head or the stock PCX150 / SH150i or Vario 150 eSP head.

※ This cylinder kit need to be installed with a 170cc/min B-Type fuel injector! (LINK to injector page)
※ Recommend to be installed with at least a 150cc header/exhaust.
※ Recommend to install our larger aluminium radiator with 1.6 bar cap to avoid overheating issues (LINK)
※ The cylinder head nuts neet to be tightened at 27Nm (2.8kgF-M)

※ You don't need to have a ECU controller to make your engine run perfectly fine, fast and reliable if you have the correct injector size installed.
It is true however that you would be able to get even more power out of your engine if you would have a controller or standalone ECU installed, mapped by someone who knows what he is doing (don't underestimate the last part of this phrase...).
