I recently bought my first Wing a 06 with 18,000 miles. Last Saturday went on a Gold Wing sponsored Toy Run. With around 750 bikes taking part, there was a 20 mile run at 20 to 30 mph, with also a few stops, first & second all the way. About half way I checked the temp guage and was surprised to see it up over 3/4 of the guage. So I using 3rd and fourth to help keep the rpm's down. That did help, and it did go down to the normal half way. When I got to our distination I asked another 1800 rider and he told me that the 1800 will do that some times, and I did the right thing to get the temperature back to normal. He also told me not to worry about it. Should I worry about it!!!
