On mine I made spacers for the oil cooler and ran it as is. I tapped into the oil galley plug on the right side of the engine below the ignition pickup cover. I drained back in to the lockup cover. If you see a lot of street use get the HSR Mikuni 42mm with the Mr turbo High pressure needle and seat. IF I rember right you need a 15 pilot jet and a 230 main jet. If you do much 1/4 mile get the bowl extender.1/8th mile it's not such a problem. mine rode good and a lot better than my 1150 turbo I have now with the S&S carb.
