New to the ATV World

Hi. I am new here.

I picked up a Honda TRX300FW last year. I traded a horse trailer for it.

I enjoy it but one thing if I may ask, it seems to overheat and shuts down.

What causes that?

Thanks

We need the year...

Someone might know of a common cause on that model and year etc, but if we are to diagnose it, we need more detailed descriptions.

Have you read the owners manual, or a workshop manual ? You might spot the answer..

Have you tried giving it a service.. spark-plug, air-filter, valve adjustment, idle speed and mixture, fuel filter and vacuum hoses. It's always recommended to check the service and hose conditions etc.

And, when you say it overheats and shuts down, how sure are you about those two things being linked ?

It could be that some electronic part is overheating, or the engine might be getting hot and running lean at idle, or perhaps, getting a tight valve, or, perhaps the fuel tank vent isn't clear and it's not heat related at all.

Describe how it "shuts down", is is instant or does it come stuttering to a stop, does it restart immediately, after five minutes, after an hour or more ? Does it start easy from cold, and hot ?

Hope that doesn't sound harsh, but we can send a lot of money doing things and replacing parts that aren't needed if we start guessing..
