Duncan Butterfly Bearing Mod?

Hello. My friend has gotten two Duncan Butterflys (Butterflies). They are fixed axle and do not sleep. Can anyone help me figure out a way to make it sleep? Such as a bearing mod? I want to surprise him with the solution.



Well, use a needle to pick the loop to see if it’s single or double looped on the axle. That’s the case most of the time. other than that, if you try to take it apart then it’ll break. Maybe he should get a take apart yoyo like the Duncan Reflex or FAST 201 for beginners
