I have a 2012 summitx 800 etec. I had been running boyesen rage cages for 2 seasons. I decided to check them this fall because I had heard they had problems in etec motors. Sure enough they were cracked! I was going to install my stock reeds, but found they were chipped on the edges. Fortunately I was able to get both sets warrantied. So now I have to decide which ones to install. They are both the updated versions. The new boyesens look a lot better(o-ring seal & full carbon petals, similar to their turbo reeds). The doo reeds also look a lot different(new petal material & shape). Has anyone tried the updated boyesen? I haven't found much feedback on them. They are the RAD88A-2 part #. Or am I better off just running the updated doo reeds? (how have they been holding up?) Not much snow around Tahoe area so I have some time to decide.
