Description

● YUMINASHI EVO SINGLE REINFORCED VALVE SPRINGS SET (2PCS/SET)

● The Yuminashi EVO Single Reinforced Valve Springs were specially designed for the Yuminashi EVO, EVO-R and EVO-RS big valve heads, with big valves, high performance and high RPM's in mind while racing on a circuit track or drag racing strip.

● These valve springs have been designed with high RPM's in mind where the reciprocating mass of the single valve springs is less compared to double valve springs.

The Yuminashi Titanium Retainers come as standard in all Yuminashi EVO Big Valve Heads, and are the recommend retainers to be installed with the EVO Single Reinforced Valve Springs.

● The Yuminashi EVO Camshaft is a high lift camshaft, where the open coils design of the EVO valve springs has been worked out in such a way to create a valve spring which is not only Heavy Duty but prevent also coil bind when the valves are at full lift, and this in combination with high RPM's, and larger, heavier valves.

※ Free length: 34.30mm
※ Maximum compression possible before coil bind: 21.85mm compression possibility
(Possible to be used with extreme high lift cams)

● The Yuminashi EVO Single Reinforced Valve Springs can be installed on all stock/standard Honda 125cc and PCX-style 150cc 2-valve cylinder heads.
Both 125cc and 150cc heads can use the stock/standard retainers, which we don't recommend with a racing situation in mind.

※ We recommend to check the free lengths of the valve springs every 3th race and to replace as required.
※ A rule of thumb is to replace the valve springs each time you replace a piston...
