    Both pistons are equally as good. Many of the guys went with CP early on after seeing others having problems with the Riva's and valve to piston contact. Riva has since resolved the issue with the manufacturer (MTC). If there are any performance advantages will someone follow up with this post please.

    I'm running Riva and have no issues with it. I read a post earlier that a member had a problem with the cp pistons hitting the oil sprayer and need shaving. Can somebody chime in to confirm for our benefit. I also read on the instruction that the cp piston require a little more piston to block clearence compared to the Riva. Does it mean Riva has better themal stability. Not trying to be bias but trying to understand the facts. CP is a lot less$$$ thou. Thanks.

    The oil sprayer can be adjusted to clear the piston.
