I own a 08 Dyna FatBob. I bought the bike in August and rode on a few hot days. I could tell the bike was hot. How hot, don't know. I'm going to be taking it to a Stage one as soon as old man winter says so. What constitues an oil cooler? Should we know what our oil temp is? I know going to a Stage one with more air and TFI will cool it down some. But how many of you out there have a temp gauge and oil cooler. If so, what would be the best way to go? I've seen a temp gauge on the cap. Accurate? And how hot is hot? How hot on the oil temperature tells us we got problems. Thanks.
