Gen II Hayabusa High Volume Oil Pump Gear & High Pressure Bypass Valve
Gen II Hayabusa High Volume Oil Pump Gear & High Pressure Bypass Valve
  (Enlarge)  

The High Volume Oil Pump Gear is a direct bolt in replacement for the OEM oil pump gear. This gear causes the pump to turn at faster speeds which increases oil volume and thus pressure at a lower RPM.

The gear on the clutch basket does not have to be changed. Initial testing revealed the following improvements on the test bike: 3000RPM, 32psi with stock gear. 52psi with high volume gear. 6000RPM, 72psi stock high volume gear. A must have for all Hayabusa engines that are subject to high performance type riding.

*It is normal for there to be a slight whine noise coming from the water pump area until this gear "seats" in.  

The High Pressure Relief Valve allows oil pressure to keep climbing up to 110psi (40psi higher than stock) to ensure plenty of oil flow to key components such as rod bearings and cam buckets.

Includes:

  • High Volume Oil Pump Gear
  • High Pressure Oil Relief Valve
