    Whats the top speed on a 99stx 900

    I bought a 99 stx with a blown engine, I built the engine and took it to the lake, on the display it will only run 39 mph @ 7200 rpms. Is the gauge accurate? It runs great but my 96 slt-780 will spank my 900. Does anyone know what the top speed is supposed to be??
