Need HELP?! My Spyder is running Hot at High Speeds?

[tjranch9]

I need help figuring out what's going on.
When I first got the bike (a 2016 F3L), I had a problem with it running hot and it was low
on coolant. Fast forward to yesterday coming back from Daytona. Cruising along at 80 with
cruise on and all of a sudden it slowed down, no cruise or power. The temp gauge read one notch
down from the top. The bike slowed down and I was able to do about 60 - 65 mph.
After it cooled down a little, everything was ok again. This morning, I checked the coolant cold and
it's right on the cool mark...

Any help will be appreciated.

Check and be sure the radiators are not plugged up full of bugs or some kind of bloom from the air.

Check the direction of the fans changing as it should.

Possible in an older radiator the cores inside the radiator could be partially blocked. You can't see that from the outside. A shop that specializes in radiator can boil the inside passaages out and clear them.

Make sure none of the hoses are pinched, kinked, or collapsed. Thermostat could be mallfunctioning or not opening completely.

Lots of things it could be. You just have to eliminate the possibilities one at the time.

The Bike only has 13000 miles on it. It has a bug screen in front of the rad.
This only happens at high extended speeds, other wise, it's nominal.

You did say coming back from Daytona, and Florida has bugs like you wouldn't believe. Little tiny ones that will go right through screens. Big ones that splatter all over the front end. Got plenty of small blooms and pollen too. It collects on everything this time of year. Even if you have screens, you should still check the radiator for plugged fins. I live in Florida all the time. This is the time of year when little mud wasps plug up narrow spaces with wet mud that dries like cement and dog fennel blooms blows with the wind and gets in everything.
