    cold starting with hot start lever

    by phil » Fri Dec 21, 2007 7:38 am

    i can't seem to cold start my 06 crf 250 under 15 kicks any other way then using the hot start lever.

    one day i tryed starting it normally and it took me about 20 kicks to get it going. the next day it took me 2 kicks with the hot start lever.

    am i doing something wrong in starting this bike?? :?

    What you are experiencing is opposite of what normally happens when it gets cold. Cold air is denser than warm so it has a higher oxygen content available. That usually means that your starting suffers from a slightly lean condition. Since the hot start allows more fresh air, you should be leaner still.

    What is your normal starting regimen?

    Sounds like a closed right intake valve.

    One of the symptoms is hard starting overcome by the use of the hot start.

    How many hours/miles?

    When was the last valve check?

    Hi Guys. I've just picked up a new 08 crf250r. I too am having trouble getting started.Its my first time in a while with a kickstart after a few years on the 250X. I race Hare Scrambles and Enduro events here in the UK -these all start with dead engine starts so this really effects my results! . The bike is 4 hours old and completely stock - the only adjustment ive made is to the tick over - ive adjusted so that it revs a little higher at idle so that i dont stall at low speeds in the slow technical/forest sections. Any advice for me? I now have a right leg the size of a power lifter!

    Try opening up the fuel screw 1/4 to 1/2 turn.

    For anybody riding either R in Hare Scrambles I have to plug the Rekluse. Imagine never stalling your bike once in the whole two hours.
    They work and work great in just such an enviornment,and that's why in the States you're seeing more and more of them being used in off-road races, including more and more in EnduroCross running them,and this is by top riders.
    Your bike should be starting very easily being that new, you should be able to start it with your hand in one or two kicks. I would remove the pilot jet and clean it with high pressure air and contact cleaner, and of course do as recommended open the fuel screw up a bit.
    Just because it's new of course doesn't mean you don't have dirt in the fuel system, with a new bike you should have starting difficulties. One thing that really works well to diagnose that is say you kick the darn thing 10-20 kicks and it doesn't start.Take the time to pull your tank and plug. If the plug isn't wet after all that kicking you've got a fuel delivery problem.
    I assume you're taking great care to not give the thing any throttle while kicking, because if you're like some guys who can't seem to help but to twist the throttle while kicking you'll never get it down.
    But first, open the fuel screw, if no luck pull the pilot jet. Doug

    Cheers Doug - your a gent! I have heard so many good reports on the Rekluse....could be my next purchase! I never touch the throttle when kicking however i do sometimes give her a few quick twists before kicking if she's been stood for a few weeks. I will resist and adjust the screw instead and let you know how we get on. Thanks again. Jamie :)

    funny, today i turned the petrol on then kicked once and it started first go without the hot start lever.

    could it be my finishing regimen? is there a special finishing for the day regimen?

    You could turn off the fuel and give the throttle a couple of blips before shutting down. It is usually more important to have your fuel screw opened a bit more when the weather turns cold. Another thing we do is give the throttle 2-3 whacks before trying to light it up.

    Hi guys

    Sorry ive been away so long! My start regime is quite simple.
    1)Turn the fuel tap on
    2)Open the choke
    3)Push the kickstart through its stroke until i find the compression point (about 1/3 through the stroke).
    4)Then kick her.
    I never touch the throttle. I can do this 8-10 times and she wont fire up.
    5)I then give the throttle a few blips and repeat above.
    She'll fire up after another 5-10 kicks.

    If all the above happens on the start gate, its usually ends up with me waiving to anyone who can help and give me a push!! ha ha!!

    Ive opened the pilot a 1/4 turn and this has helped but not cured it. When she does fire though , she seems to race and then idle, then race , then idle at tick over - only slightly , but it is noticable :?

    I think i'll clean the fuel line and check the carb and see what happens!?

    That's a sign of lean jetting.
    Open up your pilot screw about 3/4 a turn more than you currently have it.
    Add to your starting proceedure "blipping the throttle" 3-4 times before your first kick.
    Also may need to readjust your idle setting after playing with your fuel screw. Generally, richening the fuel screw will cause the idle to drop, which could also cause frustrating start-ups.

    Draining float bowl and getting fresh fuel also seems to help.
