About that fan...

[jjg3]

09 Nomad, no engine mods, just over 5k miles. Not sure but I don't think the coolant has ever been changed. My commute is a relatively short 15 miles/20 minutes mostly interstate at 70-80mph. I've only noticed in the past couple of days the fan is on at the end of the commute. The ambient temps have been in the 60s-low 70s. Last week was around 100 one day. Have felt heat coming off the engine but not more than I would expect for having a big cylinder between the legs. Is this normal for the big Nomad? I'm ok with it if it is, would just like to be sure since I've only had the bike a couple of weeks.
