This 3,000 mile sled acts like it's not getting fuel at higher speed / rpm. I can start it up, and for the first one or two minutes it runs perfect. Then it starts to "bubble" at around 50 MPH, bogging down slowly until I can't even reach 20 MPH. It would probably stall if I kept the throttle open. If I stop and turn it off for a minute, it'll run perfect once again for another one or two minutes, then start sputtering all over again.
I've checked the fuel pressure at idle - now right on after changing a faulty fuel pressure regulator. I have also changed the gas lines in the tank. New spark plugs and recently removed and cleaned the valves.
By the way, if any of you have an '06 Polaris, I would suggest pulling the guts from the gas tank - although I make a point of using premium fuel, inevitably some blended has gotten through making a mess out of the gas lines. I literally dumped handfulls of tubing and loose pick-up filters from the tanks of my '06 700 classic and my '06 700 Fusion.
