● YUMINASHI 3MM ALUMINIUM SPACER GASKET SET (FOR 4MM STROKED UP eSP+ ENGINES) (12191-K1N-A03S)
● YUMINASHI 3mm (0.11811 Inches) Aluminium Spacer Gasket Set to lift your eSP+ 125 or 160 cylinder up by 3.35mm (3mm aluminium gasket + 1 extra cylinder base gasket= 3.35mm).
● With this spacer gasket set you are able to work the correct piston deck height out with a 2mm offset crankpin installed (=4mm longer stroke), or with the stock stroke crankshaft and a 2mm longer connecting rod installed...
● If you are looking for a way to boost the cylinder displacement and the torque of your engine on a safe and reliable way, then the 2mm offset crankpin set (LINK) results in a 4mm longer stroke (as shown in the guide below).
● With a 4mm longer stroke installed on a 60mm bore you get a square engine, which is an engine with the bore diameter equal to stroke length.
※ This set comes complete with 2 paper cylinder base gaskets in the package, the idea is to install 1 gasket on top of the aluminium gasket, and 1 gasket below the aluminium gasket.
※ We recommend to remove the stock cylinder studs and to replace them by the 216mm (8.5Inch) Stainless Steel longer cylinder studs (LINK).
※ You don't need to install longer dowel pins, but you do need to install a 2-links longer (94L) cam chain (LINK) in combination with a 3mm aluminium spacer gasket set (LINK).
※ Remove the cam chain tensioner from the cylinder block before you install the cam chain!...
※ Install always a new gasket between your cylinder block and your cam chain tensioner, if you don't do this then your cam chain tensioner will leaking oil and make a ticking sound.
