    rpm for wide open throttle on stock sts750?

    I have a 1995 kawa sts 750, dead stock, that I am putting an engine in, and I would like to know (after break in) what kind of RPM I would expect from this engine. Before the piston skirt on the mag piston seized, it would turn just barely over 6000 rpm at WOT, but ran very nicely getting there. It would be a good clue what this engine/ski combo will turn as I try to figure out what went wrong. thanks in advance!

    sounds about right. most likely you were running lean and you seized and melted down
