Hej,

Couple days ago bought a 2006 Yamaha XJR 1300.
As a new owner and rider, kind of just winged it and bought the one I can afford in the style i liked.

In general motorcycle runs smooth after got used to using choke and throttle stop screw. (setting to manual suggested ~1000 rpm idle)
But have one big concern regarding temperature.
Dont have built in temperature gouge, but it feels hot and it is.
Used external infrared thermometer to measure temperature.

After nice fast 20 minutes drive : ~120c engine (250f), 180 exhaust, 108 radiator

10 minutes idle after drive :~150c engine (250f), 195 exhaust, 108 radiator
image0.jpeg image1.jpeg image2.jpeg

Manual states normal range 60-105C
Checked radiator seems not be damaged and there i no active fan or any liquid container.
Is this normal for this type of old air cooled bike or there is a big issue with the engine and I got screwed badly :) ?
If there is an issue, how urgent it is and what it could be.

Thank you very much for you input and help, will be much needed and appreciated.

I think you are fine. I believe this bike is air cooled and the "radiator" you see is probably an oil cooler.
Don't idle it very long because it can't get air over it's cooling fins when not moving.

Feels very hot, but thanks .

Will try to take it to some service to see if any of that would help.
As could not found any aftermarket options to increase cooling.

just hope that was not sold on dying bike

it's air cooled, there is no upgrade for that. Just change the oil when you should and ride it.
