    See my signature links for more info on the red 'domestic' Polaris 2-stroke carburetor engines.

    The intake grates are interchangeable.

    John Zigler of www.watcon.com is an excellent source for carburetor rebuild kits and other parts.

    It is common for the MFD display hours to accidentally reset. Do not reply upon the hour counter to determine actual engine condition or wear. Use your own inspection and measurements to determine engine health and general mechanical condition of the machine.

    Judging by the lack of fading-it is possible it only has 9 hours in the sun.

    It looks like it has a "primer" knob, just in front of the seat- that would have been added, usually if the carbs have been changed- post some pictures of the engine-you will need to know which carbs you have to get the correct rebuild kits.

    The 150 psi compression is higher than stock-make sure you use a higher octane fuel.

    And yes,the SL ride plate will fit this 1050.

    Those are the original carbs (Keihin CDK 2 ) (with out accelerator pump) and the choke plates are still in place. For cold starts Polaris uses the choke-most aftermarket carbs don't use a choke plate,so need a primer for cold starts. (some times people prefer the primer/remove choke plates-but it is usually one or the other)

    You should take a look at that knob mounted just before the seat to see what it was used for.

    are you talking about that knob ? its for engine fogging
    what is this accelerator pump?

    thank you for replying

    LOL...engine fogging sounds good. I got the primer stuck in my head.

    Polaris had 2 versions of Keihin carbs one with an accel pump, one without. It still should use the same rebuild kit-just nice to know what version you have.

    what does the accel pump do ? does it get higher top speed ? can you link me them what are the prices for it
    thank you very much

    In the picture ,notice the extra bulb by the front carb,that's the accel pump.

    It's just a different carb design-no increase in speed,but in my opinion it seems to give better take off.
    It literally squirts fuel into each carb when the throttle is sqeezed.But doesn't add any fuel at top speed.

    You would need to do considerable modification to add it or buy a used set of carbs.
