temp light keeps comming on HELP

[2ltrmirage]

my temp light is starting to come on alot now. ive had it for about 9 months and never seen the light on once, now every time i rev it high it will come on, then after a few more revs it will flicker off for a second.(sometimes it will stay on for an hour or more , i can even disconect the battery and hook it back up and it will still be on) its not spewing coolant over or anything, so i dont think its over heating. ive called the dealer and they are no help at all.

my coolant is full (engine ice) and oil is full and there dosent seem to be any bare wires anywhere.

its starting to realy get me mad. i hate everytime i ride looking down and seeing that light on, i cant even ride for 5 mins without it comming on. i dont know what to do, hopefully someone can help.

anyone had this problem or have any suggestions?

Does it come on soon as you start it or after it warns up.

Make sure your raditor is clean because its really hard to clean .

It takes me about 25 mins to get all the dirt and mud out after a mud race.

[2ltrmirage]

sometimes as soon as i start it, sometimes after a few mins.

its spotless clean, and just flushed it and put in new engine ice.

Does the fan ever come on?

[2ltrmirage]

yeah the fan will come on and kick off, but the light dosent always come on or go off with the fan.

the fan is working though.
