just installed an oil cooler in the usual spot on a cb750f, up in front of the top of downtubes. also have a temp guage threaded into the fins on head at #2 exhaust port ( i know not terribly accurate) without the oil cooler bike was running consistent 160-165 temps going down the road. now that the cooler is installed, i noticed the temp is roughly 10-12 degrees warmer under same conditions. is this because the cooler sits in the air flow over the head?
