    Polaris virage idle problem

    It has problems running on idle, first i thought it was the fuelpump but i took it apart and it looks fine, now i think it is something with the carb, anyone having an idea`?

    Welcome to the hulk

    Is this Virage new to you?
    Which model year?

    Has it ever worked properly?

    Two or three cylinder engine?

    Carburetor, or fuel injected engine?
    (I know you mentioned the carbs - just need to be sure)

    Does the engine run properly otherwise?

    What is the maximum sustained RPM on the water at full throttle?

    Have the carburetor(s) been cleaned and rebuilt recently?

    Yes, its new to me (2 years), its a 2001 2cyl 700cc 1carb model, not fuelinj. It was working fine before the end of the summer when suddenly this problem appered. its rpm is 7200 at 43knots witch i think is the correct rpm. no the carb has not been rebuilt recently, i did take a look at the carb and the fuelpump and i couldnt find any crap in them and no visible/obvius problem but im not a mechanical :P

    Your profile says "Yongwang polaris replica"
    Do you have a genuine Polaris PWC, or something else?

    You have had it for two years - correct?

    43 knots - how was that measured?

    7200 RPM is the rev limiter in the stock Virage CDI ignition. Normal maximum operating RPM in the water should be well below 7200RPM, unless you have a modified engine or impeller.

    Unless you take the carburetor off the engine, and dis-assemble it, you can not tell if it is clogged internally. The symptoms you describe indicate it could be clogged...

    When the carburetor is installed on the engine, all you can see is the air throat though the carb, not the small internal parts and fuel passages.

    When you get it started, it will not idle - correct?
    But if you squeeze the throttle, it will keep running, and will run up to full RPM and speed on the water, but not idle. Is this what is happening?

    yes its is a copy of a polaris virage but it is exact as the orginal, they said when i did buy it that all polaris virage parts fits on the scoter, even the hull. the maxspeed is measured with gps. no engineparts changed :P

    Hmmm...

    We have very little knowledge of the Yongwang Polaris replica machines. Even though they claim it is an exact copy, the devil is in the details.


    Note: 43 knots is about 50mph, or 80km/h

    We would be interested to see some clear photos of the engine area, the jet pump, the hull interior, the digital instrument display, and the carburetors. The more, the better.

    Is there a service manual available from the manufacturer?

    What brand and model is the carburetor?

    What is the HIN number on the rear deck plate?

    It would be interesting if Yongwang actually purchased the ignition components from the same company Polaris used - PVL (Probosch-Vogt-Loos GmbH)

    Other Polaris OEM electronic components (LR voltage regulator and Start/Stop modules) were supplied by Minks Engineering in Kissimmee, Florida.

    The Polaris OEM wire harness connectors are a mixture of Deutsch and Delphi/Packard (P.E.D. Weather Pack).

    Is the service manual in paper or electronic (PDF) form?

    Keihin carb copy?
    This could be interesting, or frustrating...

    Where does Yong Wang suggest you go for replacement parts?
