   Does anyone know if it is possible to beefcake a Duncan Mosquito? And can you add thicker duncan spacers in it? I know you can't add YYJ shims in it.

                        Thanks,

You can beefcake it. But you can’t add thick Duncan spacers in it or else the string will get caught in the bearing. And you can’t put YoYoJam Spacers in it either, they won’t fit.
