Cold Start issue
I have an 03 with 8500 miles, out side its been between 60-90f. I have a hard time getting it started while it is cold... After the motor gets warm it will recrank fine. I have, Changed oil (mobile clean 5000 10-40),Cleaned air filter, ran seafoam, Replaced fuel filter, replaced plugs, Adjusted the air/fuel mix to what seems to be near correct... fresh gas, Cleaned carbs,... tried boosting from a good car battery just to check cranking power. Throttle nor choke seem to make much of a difference.... Even after i get it to crank it still wants to die out until warm... Idle knob is adjusted to approx 1700 rpm while warm... Thanks for all your time

My thoughts are that the pilot jet is clogged, but the bike should run if the choke is used on a cold start. is the choke cable adjusted properly at the carbs?
try seafoam again by pouring some directly into the fuel hose so it can be drawn full strength into the carbs. let it sit overnight with that high concentration in the bowls to give the seafoam a chance to break down the goo and try starting it again in the morning. |

Kelly, Remember the good old days when we did not have to worry about "goo" in our gas. Boy, have they screwed up fuel these days!

are you saying you just did this a few minutes ago or before the problem started?
when you soaked them, did you remove all the jets and did you blow out the passages after the soak? |

You wouldn't be referring to "Ethel" at $0.25 a gallon would you

remove and clean the jets and passage ways.
unless you do this, your not really cleaning a carb. did you do this previously? |

did you look down the middle of the jets to make sure they were cleaned out? you should be able to see a nice clear hole down the middle.
did you blow out the passage ways w/ compressed air? were you able to feel air passing through to the little exit holes in the carb throat area when you blew from the removed pilot jet passage?? http://faq.ninja250.org/wiki/How_do_...n_the_carbs%3F |

Just cleaned the gas tank completely and filled up with new gas...would valve adjustment cause a situation that would not start but hesitate a little like it wants to?
