Why is it needed
With people pushing the limits of the H2 platform & often producing more than 30% more power than even the stock H2R one of the major issues that hasn't been addressed is the lubrication system. While the factory oil pump is fine for the stock loads within the engine many people are experiencing conrod & main bearing failures due to low lubrication pressure when additional boost & engine load is added.
Factory oil pressure is anywhere from 22-37psi *depending on model* measured at 50 DegC & 4000rpm although this can go as low as 5psi at idle at operating temerature, this is too low in our opinion for a performance engine.
Why are these engines affected
The H2 family of engines have additional shafts within the engine to support the supercharger system, these all have oiling passages that bleed off some of the oil pressure, this combined with the fact that Kawasaki runs the oil pressure low to help with engine efficency & to pass emmission standards. Again this is fine for a stock application but not ideal with increased engine loads.
With the help of some world record holding Drag racers, We have developed a simple solution that still allows the factory water pump to remain in the stock location while incorporating a wider oil pump Gerotor that supplies additional flow & therefore pressure to the system. We have been testing these pumps for over a year with excellent results.
What's included
Oil pump Gerotor: Produced from high quality high strength EN26 steel our oil pump Gerotor is precision ground & polished & supplied oiled in a sealed bag with a new hardened drive pin.
Oil/water pump body: Machined from High quality billet aluminium & anodized black, fitted with new genuine shaft seals & a new O-ring.
Instruction sheet on how to assemble & install your new pump & some silicone grease for assembly.
*Important* When modifying the lubrication system on your motorcycle we highly recommend monitoring of the engine oil pressure using an oil pressure gauge. Pumping additional oil around the engine can potentially aerate the oil more & cause oil foaming during prolonged high engine speed (eg:circuit racing) so proper oil pressure monitoring is essential.
