TRX250 Idle Problem

Yeah, it's not a KLR, but a few of you guys seem to have ATVs and a lot of knowledge with engines in general, so maybe somebody can help me out.

I've got a 2011 Honda TRX250 with an annoying idle problem. The thing won't idle well until it gets hot. If I adjust the idle speed screw to where it will maintain an idle when cool, by the time it gets hot, the idle is way too high.

Is this just common for these things? I don't see any way to deal with the issue aside from the idle speed screw and it's not doing me any good.

It's not too bad in the Summer when it's hot out, but this time of year you have to ride it like 5 miles before it will even idle without dying with no throttle application so it's kind of a pain in the ass.

If anybody has any thoughts on this, I'd be interested in hearing what you think.

I don't know if adjusting the throttle cable might be an idea, or would just duplicate my efforts with the idle speed screw.

planalp,
I'm not the Honda mechanic but, I'd start with MAX valve tappet clearance.
Then carburetor, disassemble and clean.
Probably drill the EPA 'tamper resistant' cap over the LOW speed mixture screw, BEFORE cleaning!
Set mixture screw at 2 turns open, as base-line. Adjust as needed, just like I'd advise for any KLR.

Thanks, pdwestman. Since the thing only has about 20 hours on it and has done it since it was new I was hoping it wasn't going to be anything complicated.

Would not be the first "over screwed" idle mixture screw or "over tight" valve tappets, WE have seen on this or any site.
Basic mechanics, 101.
