Question about 2003 Yamaha YZ 250 F
I was riding my bike and ran out of gas. so i poured more gas in and was riding then it shut off on me. i kicked it like 20 times and then started again. after like 2 miles of riding it started felling like the bike was losing power. once u got out of power band it would try to bogg out. now it wont start unless u push start it. and when i do push start it, it still takes a while to start it after i have already popped it into 2nd gear like its flooded or something. when i get it running it still trys to bogg out in low rpm's. what should i do? i hope u guys can find a solution, thanks.
Sounds if you picked up some water/dirt in fuel when was low
clean fuel bowl and flush carb by drain port if still ruff then remove carb for cleaning

Have you made any airbox or exhaust modifications? (too oily air filter, clogged chamber, dented header)
Are you running stock carby/jets? Using the correct range sparkplug?
Check condition of reeds, they may have relaxed their tension and are remaining open, or been damaged by carbon blowback.
Are you using the right fuel at the correct ratio?
Are your crank seals in good condition (is there any sign of fuel oil weeping from behind magneto?
Are the conrod and crank pins okay? (excessive piston side play or up down freeplay)
Is your ignition providing a healthy spark? (coil condition and good earth)
All these issues can have a bearing on your problem, goodluck.
