    My 09 runs at about 210 on the temp dip stick with HD mineral oil, i will be changing to synthetic at the next change and from past experience would expect it to drop about 10deg.

    HD consider 190 - 230 to be normal range.

    Quack is new around here, lets give it a bit more time before we start hijacking his posts
    As for polish - look at my name and ask yourself if you should be asking me about some thing so fragile

    On my 03 Softail I would run about 190 in the winter time and 210 to 220 in the summer, with Harley mineral oil. Haven't bothered with an oil temp guage with the RKC. It's interesting to note that it used to take about 20 -30km of steady highway riding to get to the normal operating temperature in winter time, which confirms the idea that short trips around towns etc are no good for your motor.
