5200 and 5600 is what there sat at, He has the limit set to 10k (9950 rsm indicated) that's what it seems to rev to anyway I see on the nistune the limit is set to 9 as far as I can remember but it revs beyond that , I wound it up that far once or twice before but no point there isn't any power up there ya can feel at about 7.5 its time to change.
