I've had one rave leak oil bad due due stem/housing wear. I've ordered two (OEM) valves and housings from OSD for this season. But it just dawned on me that my engine may be bored over, i bought the ski second hand.
Is there any way to determine if i have to shave the raves without pulling the head to measure clearance? Can i use the old ones as a guide?
