Not 100% up on the nomenclature of the rzrs yet. I have a 2014 800ps h.o. Im not sure what threads i am supposed to be on? Also curious on what width it is? I guess other then doing maintence on it, what the hell it is lol. My title doesnt tell you squat about it, And i never got a book with it. I need all the info i can so i can figure out what compression ratio it has because the P.O. dusted it and i want to get the correct pistons for it. It runs great, has 170 on the pump, but juat has that annoying piston rattle with no oil useage. Any insight is very helpful and I thank every one in advance and look forward to the great discussions!!
