I’m having issues, with my 97 king quad 300 ltf4wdx, the oil temp light comes on. Almost everytime I start it up and let it idle, I’ve cleaned the oil cooler, I’ve checked all lines, there isn’t any obstructions, for the oil not to flow freely. The oil cooler doesn’t seem plugged up or dirty. It’s not running lean. I’ve replaced the temp sensor twiced and still no change. There isn’t a winch, or any other accessories added to the quad either. So nothing is blocking the oil cooler from getting air, any ideas??

I'm not sure how that thing is set up, but is it possible your oil pump is not putting out full capacity? On the Z400 there is an internal screen in the cases that can become clogged. Not sure if the 300 did something similar. My 88 250 FWD had no oil cooler on it. Not sure when they added that.
I cleaned the oil screen, out a while back and it didn’t seem to help it. I had in a shop, a few months ago, and they tested everything , said compression, leak down test, everything was good on it. Surprisingly so I’m not sure what wrong with it.

Not sure what else you could do. If the fins are clear in the cooler, the only thing I can think of is to try and richen it up with the fuel screw, try to cool it a bit that way. You might be able to simulate that with the choke, but I think that jacks up the idle, so may not work.
Yea , carb is set perfectly, it idles and runs great, just throws that light, after so long of running it, and that includes riding it. I know it has to be overheating, but not sure why, exhaust isn’t plugged up or anything either. I’m thinking I might just have to rebuild the motor maybe. Which I’ve never done or know anything about.
Yea, which I’m sure, piston is not seized up, and I know cooling fins are clean. It runs fine just overheats for some reason.
