Our new oil system adaptor eliminates the
restrictive internal oil galleries of the Hayabusa
engine. The adaptor removes the drilled,
sharp-edged, and restrictive 90-degree
passages in the stock engine. The oil from the
pump is routed through our adaptor straight into
the main gallery to provide positive pressure to
the critical connecting rod bearings. It eliminates
the stock oil filter and is available with  -8 AN or,
our recommendation, -10 AN fittings. With this
system, you will run oil through the oil filter before
the oil cooler. This will insure any debris is
captured in the oil filter before it enters the oil
cooler and contaminates the engine oil.

For those who are using an oil accumulator you
can route the accumulator to the center feed of
our adaptor.

We also manufacture wet sump oil pans and a
windage tray/ baffle to keep oil around the oil
pump pick up during hard cornering.
