I got 2 Duncan Imperials and 1 Duncan Butterfly from walmart with a giftcard. Does anybody know any modifications I could do to them? Just throw some ideas out there, I don’t care if they’re risky, as the yo-yos are only $3 each.
you can mod it with bearings like in this topic but its hard to make it http://yoyoexpert.com/forums/index.php/topic,5835.0.html
You should of bought a Mosquito, much easier to mod. 
Anyways, something that’s fun to do is just sand the writing off the walls of the yoyo, so its just the color of the original yoyo, not writing. That’s all I can think of. :-\
My Walmart only had Imperials and Butterflys.
That’s not good! 
Anyways, yeah, that’s all I can really think of.
actully a put a kk bearing ing mine, recessed, SHIMED and hubs
