    01 Virage 700 Changed to Dual Carbs

    I am new to this forum and joined because I just got my first ski.

    I've had bikes, boats and other toys throughout the years but at 58 I figured it was time for a ski.

    My friend had a 01 Polaris Virage 700 for the past 3 years. He has had it in the shop several times but could never get it to accelerate correctly. So I got it from him and quickly found that the acceleration pump on the carb wasn't working. After cleaning the carb and replacing all fuel lines I got it to run better but most of the time it would bog when you hit the throttle until you past 3200 rpm's. I went into the carb a couple more time but could never get a good spray. Other than that the Ski would run about 6050 rpm and 46 mph. My wife is about 120 pounds and with her on it, it ran the same.

    I decided to put on a set of 38mm carbs off a 98 700. I rebuilt the carbs before installing. I got everything finished this morning and took her out. Acceleration is great from idle to full throttle. She now runs 6450 rpm's and 53 mph. the wife and I will go out tomorrow and I'll see if her weight changes anything.

    Now I still need to order a oil pump as I split the line I had into two and have seen on here everyone says to go with the dual line pump. I did however add oil to my fuel knowing there is air in the oil line.

    After riding about 12 miles I took it home. There I pulled one of the oil lines off the carb and no oil.

    My question is does it take longer than that to purge the air? Or is it that I split the line?

    Other than still working with the oil everything went smooth. The only real mod was getting the air box to fit.

    Glad to hear you got the carbs working pretty well.
    The 700 engines should turn around 6700 in great conditions-temp and humidity matters.

    Yeah, the oil lines are kinda calibrated by how many hoses leaving the pump. But I would guess according to the number of cylinders. I would guess it should feed enough for 2 cylinders.
    The oil pump is pretty stingy. at idle it will barely pour over the edge of the hose, like a drop at a time.


    Lifting up on the pump lever when idling will put it at a level matching full throttle and oil will be more then a drop.
    The pump does have an air bleed screw, chrome and pointing towards the carbs, phillips head? That will bleed air from the supply hose from the tank.
