I know I have mentioned oil before; but bare with me for a bit.
My Voyager is not going into the red...yet! I got it at the end of summer here.
But, I noticed (like you) that the first time the temp gauge gets warm; the fan is capable of cooling the anti-freeze back down.
Then the second or third time; the coolant stays hot.
My thoughts are:
*The coolant is designed to get hot fast and dissipate the heat fast.
*The oil takes longer to heat up and retains that heat longer.
*Only the top end of the jugs are liquid cooled. (the oil has very little opportunity to dissipate heat)
Finding a way to decrease the oil temperature should also reduce coolant temperature.
I don't know what you have in your bike. But the Puralator filters are a bit longer than OEM.
That equates to more oil; more surface area; more heat dissipation.
Synthetic oil is also supposed to run cooler.
When I changed to a Puralator filter and synthetic oil; I noticed a drop in the coolant temps by more than a quarter of a tic mark.
If next summer I am still not happy with the temp; I will look into one of those sleeves that fit on an oil filter that have cooling fins.
Our temps are not dissimilar to those in Texas (apart from the longer periods you guys have in near the Hundred mark. I have been toying with the idea of synthetic but prices for it are through the roof in Australia. I haven't heard of that filter and at the moment I'm using the K/n. Although the bike is a 2009 it only has about 25000 miles on it (i'm the second owner), most of those in the past two years. This gauge overheating has only occurred in the past year so I'm guessing something has failed or there is a doozy of an air lock in there that even the dealer has been unable to bleed out
