my yyj legacy came responsive out of the box. i tried breaking it in but it didnt work. can anyone help me ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ???
Check the silicone. Make sure you remove that little piece of plastic under the silicone, then put it back in. After that, it will be dead unresponsive. Also, check the bearing, when you flick it with your finger, does it spin well?
if it doesnt make a noise then thin lube it but if its SUPER loud blow REALLY hard into the bearing 
when I got mine it was already unresponsive.
