Old school oil cooled guys.....I have a nice 1371 motor (86mm JE pistons = 13.5:1 compression, 31 / 27 stainless valves, hard face rockers, Cam Motion cams, epoxy Flo-Tec Racing head, Carrillo rods, XC piston rings, O-ringed liners, studded, Keihin 39mm FS carbs, top end oiler kit, stock crank, Schnitz progressive wet nitrous controller, Dyna 2000 ignition, Murray custom pipe) in my 1991 GSXR and I am going to start running it on the street in Chicago. My obvious concern is keeping the oil cool! I am wondering if anyone has any suggestions for better cooling like swapping the cooler with a different/bigger model and REALLY hoping someone has an old secondary "cylinder head oil cooler kit" like the one that Yoshimura used to sell that cools the oil coming from the top case outlet with its own separate oil cooler before feeding it directly to the head. I'm in Chicago in the USA by the way. Thanks in advance!
