New to the forum guys from north Texas. Bike started giving me trouble. Ran fine ever since I got it. Fired it up the other day and almost instantly the exhaust was glowing red. I cleaned the jets and bowl out, and same thing. Any thing I might be missing?
250F 2005 yzf 250 exhaust glowing red.

Kinda weird. When I pull my choke it will not stay out. It immediately sucks Back in. Always has but it has never needed to choke. So I've never used it.
I too have an 05 yz250f and mine does the exact same thing...I only notice it glowing red when it's kind of dark outside. I would say its fine unless you are seeing it glow during the day, then I would say to adjust it to run more rich.
I'm talking it glows almost instantly. And it just started doing it. Never done it befor
What are the stock jet sizes in these machines?
Your pilot jet may be partially blocked, or you may have an air leak. How is the idle? What is your fuel screw set at?
I've cleaned the jets. The idle seems fine. I have never adjusted the a/f screw. What would you suggest. It's totally stock?
Thanks,
Cory

If its never did it before, Check your valves. Make sure they are in spec. Anytime i see or heard a modern 4stroke not running correctly my advice is check valve clearance. You could also move the AF screw.
If you do a simple google search you can read about these things flowing red after a few seconds of running. The choke will make it worse , in most cases.

Your choke is leaking air, and your hot start is probably stuck.
