2002 Honda Rancher 350 Overheating?

Hi,

I own a used 2002 Honda Rancher 350. I decided to buy a Honda because I know they are known for their durability and power, for anything I would need it for. I always noticed that my legs would feel the heat from the engine, and I wanted to make sure my components weren't overheating, before I damage anything accidentally. I used my temp. gun to take the readings from various parts, they are listed below:

These are temperatures after around 30 minutes to an hour*

Cylinder: Around 280 Degrees F
Crankcase: Never exceeded 190 Degrees F
Exhaust straight out of the cylinder: ~600 Degrees F
Radiator: Around 150-160 Degrees F

The rancher did not come with a radiator fan because it is a 2wd version, but I ended up buying one to wire to a switch, I just have not gotten around to installing it yet.

Are these Temperatures normal? Should I install that fan? What temperatures would be dangerous for the block and cylinder? I use Marvel Mystery Oil in every fillup.

My machine might be running lean because of the change in ethanol levels over the years, but again, I am no expert, any help would be appreciated!

Thanks!

I have that same quad. It does run on the hot side, not sure about temperatures though. I haven't measured mine. As long as that overheat light doesn't come on then your good. The red light next to the neutral light. It should come on on start up and turn back off so you know it's working.

As for the fan... if your going to be doing heavy 1st or 2nd hear work where your working it hard and moving slow I would kick the fan on... other than that you don't really need to. It gets enough airflow when your at speed
Lol yup I pretty much always wear jeans when riding... been burned before. Never that bad though
