so yesterday i started it and let it warm up and went for a ride around the neighborhood and also let it rip a few good times on the road and on this short little trail. i stopped and let it idle in the middle of the ride for a few minutes and also let it idle awhile after riding before i started checking and comparing temps. the highest i saw it get yesterday by the gauge was about 195. when i was checking the IR thermometer the gauge was at about 185. with the gauge at about 185 the IR thermometer showed around 140 around the cylinder, around 185 on the head and about 165 on the block of the gauge and about everywhere else on the hoses. so what do yall think?

also i tried squeezing or putting a little pressure on the lower hose and revving it. it kinda felt like water was flowing through there but it didnt feel like it was trying to collapse or suck itself together.

i think i am just gonna have to go to my local spot and ride it like i would normally be riding it and watch the gauge and the overflow tank?

Derek, did you measure around the inlet tube on the radiator? You should have taken a some measurements around the top tank where the inlet tube is.

yea i did. i dont know how accurate all this is after reading jerry's post but it seemed to be around 165 just like the hoses and gauge block were

Try a thermometer like this if you are unsure of your IR thermometer.

Stick it in the upper left hand corner of the radiator, even through the fins right up against the top tank if it will fit.

Yea the IR Thermometer was a fluke so it should be pretty decent one but I was just going off what Jerry said about the different surfaces.

If it's over heating it would spit a lot of water into the overflow right? My level would change significantly right?

You are correct! Boiling water will exit! :coffee_pc:

Try taking the rad cap off and start it to see if you have any foaming going on in the rad. Mine was over heating and I found out it was foaming up from a bad O ring in the head that was letting hot exhaust gasses into the cooling system.
