Post 300 king quad over heating
I have had this atv since 1999 and never had problems of overheating untill now. Still runs like a top when hot just hard to start and the header glows orange :flame I have been taking it much easier on it since I been having issues. But would like to get it taken care of before major problem occurr. I hear of people adding fans, but not sure witch would be safe for riding in water and mud.

Sounds like your running lean. Check the plug.

Very well could be, nothing have been touched on it since day one, other than oil changes and changing plugs but it's been years since a plug was out. I will have my driving style has changed some I ride more on gravel roads at faster speeds than I used too. Planing on a ride Saturday, any idea on how to adjust the mixture if it is lean?

I have no idea about that. Check the air filter and make sure it isnt clogged.

Jason those old Suzukis have a bad tendency to tighten the valves as they get some miles on em. The valve face starts wearing down and lets it open the valve too soon causing loss of compression. Usually it causes hard starting because of that. Sounds to me like that is your issue. I would adjust the valves and get them into spec before I did anything else to it because I bet that will fix it. I cant remember now if it is the intake or exhaust valve that wears down, but I think thats your issue.

Not sure if ya solved this, but a lean condition could be caused my a cracked intake tube (after the carb) or any place the engine can suck in un-metered air carb gaskets, any hole or crack in the intake path. The spark-arrestor clogged would cause the inverse, a rich condition.

I have no clue on C/D's valve recommendation but sounds like he knows his stuff or has history w/ the bike. This could also cause a lean condition maybe if the correct valve is stuck open at the right time.

If the header pipe is glowing, you are definitely running lean, and maybe close to melting a piston. Hope you get 'er fixed.
