That 525 FCR is the way to go.
nope im running a FCR-39 now with the JD jetting kit installed. the thing is just sick. i LOVE it. i had been meaning to do this post for quite awhile but never got the time (and trust me, it takes time....) until i agreed to sell my old BST-40 to another person. i figured if i didnt do it then, i would never get the chance again. so when i cleaned and tuned the carb for the future owner i documented the whole process.
