After boring the cylinders on a Sea Doo 787/800 947/951, or any other engine with a power valves, you must relieve the exhaust power (RAVE) valve for clearance or you will snag your rings and destroy your new top end. The old rule of standard bore and first over don't need the valves relieved doesn't always hold true. As things wear, they tend to get closer and eventually they make contact even on std bore with high hours.
