PROGRESSIVE DOUBLE VALVE SPRING

░ FOR PCX150 eSP

This Progressive Double Valve Spring Set is mentioned for the PCX150, SH150i ABS, YUMINASHI STD150 and big-valve 31/24.8mm YUMINASHI X31 LS1 Head. 

This double valve springs set is a real must because the original valve springs from the PCX150 start to float, and limit your RPM's, earlier before the electronically limiter kicks in. If your valves start to float, then you will hear an awful noise. At that moment your valves make a chance to hit the piston and this is something that you need to avoid...

These progressive double valve springs are racing springs with a higher preload and are the perfect valve springs for competition use...

**The double valve springs set come standard in the YUMINASHI X31 LS1 Head for PCX150 and are required to be installed in combination with the high-lift Yuminashi Billet CNC 8.6 camshafts.
