Out of curiousity I was wondering if I could get 2 of the YFZ 450R carbs and manage to put them on my YFM Raptor. I ask this because the are 39mm FCR Carbs and they would essentially be the same thing as getting aftermarket FCR carbs for the YFM; am I correct? Correct me if I am wrong. I am here to learn. Has it been done if it is possible?
