    Polaris RXL 650 is weak at mid range rpm

    I have a 1990 RXL that I have just rebuilt the top end because two pistons had lost compression. It started first pull but I am lacking mid range power between 4000 to 6000 rmp's. At 8000 it lets lose. It runs great on low RPM. All three pistons have 115 psi. I have changed all the fuel lines and filters and still can not solve the doggy like power issue. Any ideas? It feels like a fuel issue to me?

    Just throwing this out there, have you checked your clutch? How is the mid range without the clutch on?

    Do not run the sled without the clutch installed or without a belt installed. That said, inspect or have the clutches inspected and install a new belt. Try again.
    Polaris...it IS the way out!
