I have a 2014 Honda foreman and within about 15 minutes of riding it'll start to over heat. I have the radiator relocated . I've replaced the thermostat and cleaned the radiator until it's clean as a whistle. I also checked the water pump on it, it seemed to be fine all the props were still in tack and is wasn't seized up . The fan comes on and will run pretty much the whole time. I did notice the hose coming out the top of the radiator will get hot and the hose on the bottom would be much cooler . I don't know what else to check . Anyone have any ideas . Thanks

Was the new thermostat OEM?? If not, I would pull it out and check it per the manual. Actually, even if it is OEM I would pull it out. Sounds like it may be sticking in the closed position.
I'm assuming you used the correct size tubing when you relocated the radiator?
Did you bleed the system well after you relocated, refilled the radiator and reserve tank? Air in the system will cause overheating.

You bleed the air by:
Fill the radiator with coolant up to the filler neck. Leave the cap OFF
Be sure quad is in Neutral
Start engine and let it idle 2-3 minutes
Snap the throttle 3-4 times to bleed air from the system. You may see a little coolant "burp" from the radiator, but you may not.
Turn the engine OFF and add coolant back up to the filler neck of the radiator (the level should have gone down slightly as the coolant circulates and air is removed)
Install the radiator cap

This is why @TBRider suggested to try letting the quad idle with radiator cap off.

Keep us posted, please.

i had a ford ranger small truck, that had to be bled in a certain way or it would overheat. one shortcut was to drill a very small hole in the thermostat, to let the air bypass. is it a similar problem? i got no clue
only just enough to let the air bypass, not enough to affect the thermostat.
there are drill sizes that run well below 1/16

From the looks, Those flat mount oem thermostats have a jiggle valve, if he replaced the old with a new oem 19300-hn2-003 and it's still acting the same.

I have the radiator relocated
Sounds to me like The issue is here ^^^

I've Purged cooling systems this way >> leave the stat out, YES crack the cap, and bump the rpms up to force the coolant to cycle.

We need pics of the relocate.
