So I have been reading on here quite a bit about the horror stories of the rave valves on the 07 800r. I was trying to figure out what all I need to replace to upgrade them to the newer, less failure prone version. Can anyone advise? I spoke with the dealer earlier and they noted that the valve itself was only 45 bucks each but I am trying to determine if that is all I need. For $90 I will definitely do it just for the peace of mind. Thanks in advance.
