    I installed these Riva Gas Valves last fall in my GP1200R with ProX pistons and stock Bore/Stroke. I used the boat for the first time in May. After about 15 hours of use, the number one jug's gas power valve barely touched the piston as you can see in the photo. What clearance should I leave the valves away from the piston? I was told that the Gas valves would not hit the piston like the stock valves or R and D valves? Click image for larger version.

    The gas valves need to be cut aka clearanced.
