Hi Guys I have the 08 KX250F, I cant sing this bikes praises enough! What an amazing machine, She never battles to start 2nd-3rd kick when cold with choke engaged, 1 kick when hot using the hot start. I do how ever have 1 issue with the bike she backfires when I tap off the throttle, I would ideally like to keep her wide open all day everyday but unfortunately this is not possible. She idles fine and goes like a bat out of hell when i open her smooth all the way, the backfire is the only issue to an otherwise perfect bike.

The exhaust glow is likely no big deal. Single wall exhaust tubes can get quite hot since exhaust temps are usually well over 1000 deg F (537 C) and will heat up the header. Especially if in stock lean jetted form. I had an SR500 that I let get warmed up for about 10 minutes on a sub freezing night. When I went out I saw the pipe glowing red from the head on back about 10" (25.4 cm). Blued the chrome. Within a short time after starting to roll the glow was gone. Exhaust is definitely hot.

Jonathan, What you have is a lean or deceleration pop, adjust your air,fuel mixture screw in 1/4 turn and try it .The initial adjustment is 1and 3/4 to 2 turns out from being screwed in all the way
. also sometimes they even fall completely out causing erratic idle

I don't know about your kx specifically, but I've heard of klx250s bikes having a bent shift pin and/or shift star problem. The bent pin usually occurs due to an impact to the shifter from a crash. Good luck there. Welcome to KF.

Kx250f
whats up everyone, im new here, i just picked up an 06 kx250f and im having some issues with it. first off, the bike will not idle, i have to pull the choke to start it and it idles really high with the choke on, if i turn it off the bike will die or will have a very erratic idle and ill have to goose it every once in awhile to keep it from dying. meanwhile the bike is backfiring every so often the whole time it is running, and the exhaust header is brite cherry red. this is all happening in neutral, i havent been able to ride it yet, i dont want to ruin it. like i said the bike is an 06 and from what i can tell is all stock, stock pipe, stock filter all that. i dont have the manual for it so i dont know if everything is in spec or not. the kid that i got it from told me it backfired a little til it warmed up, but theres no way i will warm up when it wont even idle, im new to these bikes and stumped , i dont know what to do, any help from anyone would be greatly appreciated, thanks.
I cleaned the hell of the carb
