    Cold start issue

    Hi

    For cold start my PRO 1200 i have to do one of this options:
    take off filters and splash quick start fluid to the carbs
    take off filters, take off fuel line that come to carb, and pull it to carb then push "start" to bring fuel to carbs

    and only after this process engine start

    when engine is hot or so it's starts just fine

    is this is normal process?

    what should i search for? is fogging kit is what i should install?

    and second - engine is stopping when idle - could it be cause of start problem?

    thanks in advance

    You need to check compression.

    You probably are going to need a top end rebuild, or at least a carb rebuild.

    Normal cold engine starting only requires turning on the fuel selector, setting the choke, and pressing the Start button. Engine should then start within a few seconds.

    Starting fluid should not be required, and should not be used on these engines.

    Click here to update your Profile with your location, and details regarding your Polaris.

    Have you downloaded the Polaris service manual?

    It sounds like you may have several problems with the engine

    What is the compression reading for each cylinder?

    Have the carburetors been cleaned and rebuilt recently?

    Do you still have the original gray Tempo fuel lines installed?
    If yes, they should be replaced, and the carburetors cleaned internally.

    Hi, Could you get a couple pictures of your engine and carburetors?

    It could be as simple as a bad tank pressure valve or weak fuel pump.But with PRO in the name ,it is better to see what you have.

    thanks, i did update profile
    i bought this Polaris last year with broken pump, so i fixed it (thanks ShaneG who sent me assembled pump and printed service manual) but i guess nothing was replaced or cleaned, and i guess i have Tempo fuel lines, at least it is gray.

    i will open engine and carbs on tommorow

    do i need specific fuel lines or i can just buy motorcycle one in shop near by?
    if i will clean carbs and engine, do i need to some specific seals or something else?

    Replace the Tempo fuel lines, check the compression at WOT, crack open a carb and see how they look inside.

    I think we need to see photos of your engine compartment

    Those three metal fittings are called 'pissers', and they are cooling water exit fittings from the engine. They are not standard equipment on your model (as far as I know). That means that someone has made changes to the engine cooling.

    If the engine cooling has been changed, then other things may also have been changed.

    For comparision, here are some pictures of a stock (or very close to stock) Polaris Pro 1200.

    Can you post photos of the engine compartment, and the outside of the hull, and the jet pump area?

    back side
    http://s404.photobucket.com/albums/p...t=IMG_1389.jpg

    about pissers - if it's part of coolant system then i just can not imagine how exactly because this wires is solid

    also sponsons - as i can compare with stock (thank for a link) i have some custom sponsons (my feeling when i drive is i just dont have sponsons )

    and carbs - is it some custom carbs or it's just filters?
