Just put a new spark plug in my 2005 Foreman 500 ES. I just bought this quad a month or so ago and it does not like to idle when warm. Cold it fires right up, riding around it runs flawlessly, but after it’s warm and I’m sitting still in gear or neutral, it starts to idle down slowly until it just dies. Any thoughts? TIA!

You may want to check your valve adjustment. As the engine warms up your valve clearance could be closing up and holding the valves open. Since you just got it you probably don't know when or if they've been adjusted or done correctly

Sounds good. I’ll have to dive in when I find some free time. Never enough hours in the day!
