KAWASAKI ZX14
A COMPLETE VALVE SPRING AND TITANIUM RETAINER KIT FOR THE KAWASAKI ZX14.
The new APE springs feature increased pressures from seat to max lift and approx .100” more travel than the OEM springs. More than enough pressure to control the most aggressive cam lobe designs with the peace of mind that only the dual spring design can o er. The CNC machined retainers features slightly deeper shim bores for maximum shim control. Includes steel spring bases.

HAYABUSA
For the Hayabusa, APE o ers VS1300GSX-2 for turbos, nitrous or cams with radical ramps. Valve springs should never be run closer than .050” to coil bind. As you can see, OEM springs will only handle a max .380 lift. However at that lift the pressure is too low to properly control the valves at high RPM. APE springs are over 30 LBS higher at .380 -- and can safely handle up to .470” lift, or allow shimming to even higher pressures depending on the application.
