Motorcycle Repair: oil routing, harley service, oil coolers

Question
Hi Mike, I'm a Italian guy.
I want, if possible, a schematic draw for the oil routing for FXSTC 1987 with oil cooler.
Thanks a lot for you help.
Mauro

Answer
Your best bet is to get a harley service manual. It will have what you need, but it will not have the oil cooler routing since they didnt install oil coolers on bikes. The oil cooler goes on the return side of the oil pump.  All experts does not give me anyway to send pics on here.
Good luck and happy riding
Mike
