    Just brought home a new to me (2100mi used) Ulysses.

    50 degree day 35 miles on the highway to get home and I was surprised the fan was on when I pulled off the highway ramp.

    What should I expect as normal for the fan on/off? I know it's supposed to be triggered off the rear cylinder temp but I'd have thought riding at speed with engine turning between 3500-4500 rpm wouldn't require the fan.

    The dealer I bought the bike from doesn't know much about the product. I guess I can check the guys in the shop but I thought I'd check owners' experience first.

    Doesnt sound like anything out of the ordinary. The only things you can do to help remedy that more is run synthetic oil, get a right hand side air scoop, or cut vents into your undertail panel.

    Sounds normal.

    About the only time mine won't come on after a half hour of riding is if it's <35 degrees.

    I have a RH scoop on my baby that pushes air to the rear cylinder and it only runs when I turn the Key off now

    Not to mention it looks a little better because now it is symmetrical.

    BuellBoy, can you let me know where you got your right side scoop? I'd like to get one for my Firebolt.
