Update: so today I bleeded air from the system but still no change.
When it's idle it stays at 3 bars when driving hard it goes to 4 bars.

Any other idea what else to check ?
Do I really have a problem?

p.s - it's 30c degrees outside

I just dropped my trail 800 off at the dealer to check a heat issue.  I run at 6 bars, sometimes 7 and the fan never shuts down.  I think bouncing between 3 and 4 is where you want to be.

Please update.

Tomorrow I'm going to bleed air from the system , I hope this is the problem.

I Cleaned it with just water

Fan is working most of the ride . I will try to replace the temp sensor

First post 
I just put my hands on 2015 Zforce 800 EX and curious about the engine temp

engine temp play between 3-4 bars, but most of the time it stays on 4 and when going to high speed it goes down to 3.
this under outside hot temp
I cleaned the RAD and checked coolnet level

is this normal behavoer?
