'99 1200LT Running Hot

I've had my LT for 6 months. As the temperature around Dallas has gotten warmer, the bike temperature rises when I'm stuck in traffic or otherwise around town waiting at lights. I haven't redlined yet but I've come rather close.
When I'm cruising highway speeds the needle stays right where it should, at or just below the midway line.

I went ahead and replaced the coolant (yes a 50/50 mix) and changed the oil/filter but it is still behaving this way.

In order what would you guys check as being the most common problems?

It' s normal, as long as the fans come on before red line. The gauge has a greater amount of movement than ones in cars but any vehicle with electric fans does the same thing as long as air conditioning does not have the fans on. The temp sender is not on the motor, it is on the water pump where the temp of the coolant varies more.

hahahahaha It's normal, I think most of us have heard those words at the dealer on several occasions,

But in this case it is normal just as Gary45 says, my 02 did this, concerned me also at first but if the fans start at or near the red temp line your good to go with no worries. The temp climbs fast just sitting and the temp gauge is pretty sensitive, it almost makes you want to shut it off before over heating. You don't need to do that though.

Re: '99 1200LT Running Hot

One thing you might check before you settle in with the quick rise of the temp as "normal" is when the fans start make sure that BOTH fans run at same time. One is usually enough but if one stops you will definitely overheat if the second one stops for some reason.

Thanks guys,

I hadn't seen a needle do this on any water-cooled biked. I'll just ride until the engine melts. hahahaha.
