Im a firm believer in taking a NEW engine to max 1500 rpm's ...blippin the throttle here na there and keepin the rpm's changing ..dont stay in one spot ...till it is at operating temp ...shut it down an set back , have a cold drink or 3 of your favorite beverage ...an let it cool down to room temp ...do again next time go to 2000 rpm ...repeat cool down ...one more time too 3 grand ...let it set over night ...an after that ...Run it !
broke in many engines that way
