Cool Thermostat Stuck ?

Mid to high 50's today. Temp gauge never got past the second mark at around 7 o'clock. I pulled over for a smoke and let the bike idle for about 10 minutes. When I was done the temp gauge was just starting to point due south. It's been like this since the day I picked the bike up from the dealer. I have seen higher readings when it's around 90 Deg. Anyone else like this ??

On my stator failure ride it was about those temps. Not much movement of the needle for awhile. When I did stop, i didn't let it idle much though. Also, with the ride being less than 50 miles and 4 or 5 stator failure shut-downs along the way, it probably just barely got up to good operating temps!
I don't think I've ever seen mine much more than a needles width or two right of center.
But, yeah, your's sounds normal.

and heres another "sounds normal" mine goes past that second mark after I've been riding and then stop at a long red light...then right back down to it...most rides I've had the fan only comes on when I pull back into my driveway and get ready to shut her down (or that may be the only time I hear it)

On a cold day my temp gauge needle barely gets off the peg, even at 70 MPH. The only time it warms up is when it idles. I asked my mechanic and he said if I want it to run a little hotter to cover up part of the radiator, but he also said it is fine the way it is.

In the cold the thermostat wont open. The wind blowing over the motor keeps it cool with the fins like a Air cooled motor. The Liqiud in the block wll get hot and slowley circulate until the radiator gets hot. In cool weather the radiator works to good. Don't wory the oil is hot and the motor is at good temp.
Thats why there is a thermostat, if not the motor would never get to temp. By covering up the radiator you are only making the gague look better.
Hope this help

In upper 40 degree weather, mine barely makes it off the first line unless stopped at a light or moving less than 30 mph. If it goes up and I get back up to freeway speed, it drops down to the second line and stays there unless again at a light or idling for an extended period.

Normal?

Well how about I add this part. High 90's today, temp got to the mid mark, heat of the pipes coming through the pant legs, and gas tank got so hot that it started to whistle from the cap. 1. Is it normal to have a gas tank that hot.
2. Will heat-sink wrap on the pipes help, and 3. Can all this be an air mixture problem from the manufacturer? I'm in AZ and the temp is going to hit over 120 in a couple weeks and I don't want valves or radiator blow out's. I appreciate any help.

what year is your bike? Every thing sounds normal, even today.The reason I ask is earlier model tanks had no vent tube and actually vented through the gas cap itself.At 90 degrees with the engine heat and the air temp higher around the tank the gas cap has been reported to whistle with the expansion of the gasoline and pressure being bled off the tank,Some Vulcans whistle,it is weird but fairly common ,My 1500 whistles through the cap at lower temps than that, I. just put up with it.Yours sounds like it is doing every thing normal.if you want to wrap the pipe to keep the heat off your leg ,go ahead the cooling system will function like it is now ,but when you shut it down it will likely cool off the head slower because of the wrapped pipe not letting the heat sink off the pipe as fast.
