Rave valve mod.
Sea Doo 787/800 and 947/951 require relieving the RAVE Valve if bored more then the first oversize as shown in our tech tips Page.
After boring the cylinders on a Sea Doo 787/800 947/951 or any other engine with a power valve, 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.
Send the valve only we do NOT want the plastic caps or housing as they tend to break in shipping.
Rave mod for clearance $20. Per set
