I bought the car I believe undeveloped after the Kawa motor was installed many years ago, the previous motor was the old Suzuki water buffalo 750 triple 2 stroke. So I get to figure out all the problems, oil cooling is the top of the list..

The main oil gallery is big but there is considerable restriction going into the both ends at the rear outer studs, that builds oil pressure for the top end. Most people are running -8 hoses, I have not heard of many running -10. Just looking at the picture of the car body it seems you could use some addition ram air by using some hood scoops.The fitting you show is the one I am looking at. A previous owner installed the GPZ oil fitting to the J motor and probably never looked at it as I hadn't. It just always had cooling problems. These old cars always have had a tendency to just get ignored in the corner of the garage . I agree the bypass would decrease the system pressure going to the cooler, I didn't know the bypass was there until I read an older post on the board. I think to be safe I need to get that same fitting and fit it with -10 hose as the -8 hoses are smaller than the port in the crankcase.I just measured it at .603 dia. So the fitting itself can cause a significant restriction. This is not an inexpensive solution but much less than a motor. Thanks for the help.
