    Starting problems on new 250x - 2008

    Hi!

    I have a brand new Ultra 250x-08 that has some starting problems from time to time. When Iīve been riding for a while and turn it of a couple of minutes it needs several seconds on the starting motor before it fires. It feels like it is on "the choke".

    I did the 6* timing mod from start, so I havenīt tried it completly stock..

    It has been running smooth for 4 hours and is easy to start when it's just launched and the engine is cool.

    What is wrong?

    this is very common, we think an injector might leak a small amount of fuel into the cylinder after its shut off while the engine is hot from a long ride. wont hurt anything. keep riding.

    spark plugs, injectors, fuel or fuel lines or fuel pump.

    how does it run after its hard to start


    I mean if it idles smooth straight away after being hard to start, its not the injectors ( not aware of any injectors being replaced )

    could be leaking gaskets on exhaust manifold getting water into cylinders

    need more info

    My ski did this same thing once about 10 riding hrs ago.
    Was riding and we all stopped for a break, went to leave and the motor turnned over about 10 seconds before cranking.
    Ran fine after it did start and has not done it sence.

    It feels like it has to much gas in the combuston chamber when it fires, and I have to rev it a couple of times before it runs smooth again.

    Feels like jtskir15f is right, but it sucks that the injectors are so poor quality..

    I will ride it a couple of more hours and see if the problem remains..

    Is it hard to get new injectors from Kawa? It is under warranty...

    Thats what I was thinking.
    My ski idled like crap when started....removed exhaust to put on OCMS fitting...resealed with new gaskets and copper spray.....no idle problem.

    Make sure to unscrew your supercharger dipstick before it breaks and falls inside.
