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.
