2005 YZ250F. Runs good with choke pulled out even after it is warm. as soon as I ush the choke in it backfires won't run. I used nto have the same symptom on an earlier model and it was always the hot...


first of all, after the bike starts release the choke, you dont want leave the choke on until it gets warm, because it makes it a really rich mix, and it will eat the oil off the cylinder wall and you can burn the rings and cylinder wall. try this. at the bottom of the carb is a fuel screw(small standard flat head screw) turn it all the way closed, then back it out 2 full turns, that should give you proper mix, right now your running way to lean, thats why its working with the choke in. has anything been done to the bike? new after market exaust? if so it could be a jetting issue. and you are correct about the hot start.....there is a little rubber gromet on the barrel of the hot start plunger where it goes into the carb, that washer could be bad, or the black plastic boot that attatches the hot start to the carb could be bad and is allowing air to be sucked in...but i would reset the fuel screw on it first....hope this help. if not, repost and we will get ya figured out. p.s. nice bike.

Will not idle. Will not start hot or cold without throttle 1/4 open. Once started will rev well but when revs drop it cannot be recovered and it just dies. Needs choke wether hot or cold to start and 1/4...


By your description, it sounds like the pilot jet is plugged in the carb. Remove carb and clean thoroghly with carb cleaner and air, making sure that all jet passages are clear. Make sure that washer and "o" ring are present on fuel mixture screw, if so equipped. Make sure float level is correct.

Pilot screw setting.


Stock it would be around 2 turns out.

These bikes shipped with only one jet needle (unlike other Yamaha's) the bike's factory jetting is 45 pilot, NBKF needle on the 2nd clip from the top, and 138 main. This bike tends to run a little rich off the bottom, so I'd recommend running a 42 pilot instead. When it's really hot out (over 90) you can run the 135 main jet.

Screwwing with carbs is fact of life with these bikes - you will have to do some tweaking no matter what. smile.gif

25cc weed eater, will only idle


double check your carb as it should have a screw for the fuel mixture. some carbs have a plastic piece over them that only lets you move the screws so far if you need more extreme adjustment they pull out about a 1/8th of a inch then you can turn in then push it back in, same principals as making a flame on a bic lighter bigger, if you cant find it take some pics of your carb and email them to me @ prerunnerrngr@yahoo.com and i will point them out
