I'be been working on draw-thu turbo bikes for 20+ years now and have develped this upgrade/oil feed hose for the Rajay turbochargers.

Kawasaki Z650, Z1, Z900, Z1000, Z1R-TC, Honda CB750, CBX1000, Suzuki GS750, GS1000, Yamaha XS1100, they all have the same insufficient length oil feed hsoe to the turbo!  

The original oil feed hose (Pics 1&.2 bottom) is only long enough to feed oil to the bottom of the turbo, and that's not good!  My oil feed hoses (Pics.1&2 top) allow you to feed oil to the TOP of the turbo, where it needs to be.

This hose kit also includes an additional 90 degree elbow fitting (JIC-#4) should you need it as shown in Pic 5.

THIS IS THE LAST ONE I HAVE SO GRAB IT WHILE YOU CAN.
