Cool Temp gauge average?

Hi guys I'm a bit concerned over Jada's engine failure and at least one other I know of. My temp gauge works and runs up to about half way, and the fan comes on and stays there.
My question is for those who have great reliability, and may also have bought one of these bikes new, what is the normal behaviour readings of the temp gauge on the VN in warmer weather?
Do you see the operation of the thermostat visually on the gauge?
Does your Gauge stay in the lower specified region, within the two lines on the left of the scale?
What's normal?

while I cant help with the 'owned since new', I can feedback about operating temps in warm climates.

SW florida here, and my bike shows the same temp behaviour as yours.

Mine will occasionally run fan for a few minutes when I first shut it off as well, if its fully warmed up.

in stop/go traffic I have seen mine get just a bit to the hot side of the center of the gauge, but it does not go over

Mine, bought new, never went past the half mark (half being the middle of the gauge, needle running straight with direction of bike)

Once or twice it went slightly to the right when stuck in traffic. I never really heard the fan until I turned off the bike. (Where it ran 30 or so seconds before shuttering off)

As long as your bike doesn't run in the red zone I'd not be worried.

Just for the record I never had any temperature issues. My bikes temp needle always stayed to the right and climbed slightly when at a traffic light, and quickly cooled back down once I was back to speed, I checked coolant level every day before my first ride and never had to add coolant. When I had my engine failure the bike gave no signs whatsoever, it let loose without warning after the circlip somehow slipped off the impeller shaft.

2006 owner since new.....the fan only really comes on at stops when it's above 90 out. The fan kicks in at about half the guage range and the needle has never gone above half for me.

Thanks.

I can breath a sigh of relief, my bikes temperature behaviour is normal.
This site, and you guys are very helpful.
Thanks for the feed back, your are a good bunch.
Jada, I'm sorry if I offended you in any way,this was not my intent.
My reference to your tragic engine problem, was about what I feared, I may be faced with at some point.
That being said,I'm simply going through the process of elimination in my bike.
A: Check all cooling equipment,within reason.
B: Ensure all Timing chains and tensioners are, Right.
C: Premium oil and good filter,in engine.
Parts A and C being true and correct, I'm now becoming hyper critical of any cam chain noise, so manual timing chain adjusters are fully on the cards, and maybe a retention or replacement of the upper morse chain tension springs.
Have a good day.

No worries brother, I just didn't want anybody mislead and thinking my problems were coolant/overheating related.

A lotta guys dont "burp" their engines...this is needed whenever the bike is laid on its side...an unburped bike will run at 3/4 the gauge or more consistantly, wheras the same engine properly bled, will never go over half....
