I recently bought an iYoYo Shooting Star and have been having issues with getting it to play unresponsively.
I had initially over-lubed the unresponsive bearing when I had first installed it, making it play responsively. I tried spinning the lube out both manually and using canned air, but eventually decided to clean it.
I soaked it in mineral spirit for several minutes while spinning the container around and spinned the bearing as it dried. Yet, even after this, the yoyo still played responsively.
Interestingly, even after swapping the bearing for one I had never applied lube to, the yoyo was still responsive. This was after I had cleaned the area where the bearing sits too. Not even changing the string helps.
When I say the yoyo is being responsive, I specifically mean that it comes back to the hand after a tug. The harder the yoyo is thrown, the less of a tug it need to respond. It makes tricks like the plastic whip impossible unless the yoyo is thrown gently.
Has anyone ever experienced something similar? What should I do about this?
ive had mixed results with mineral spirits. the method ive started using that has been the only one ive achieved 100% success with is as follows, ymmv:
make sure your bearing is deshielded. start with dawn dish soap. use a small brush like a toothbrush and wash it out well having put the soap directly in the bearing and rinse thoroughly. blow out excess water. place in 100% acetone. swish around for about 30 seconds. let it sit for 5 min. remove and spin out the excess liquid. let dry for about 5-10 min. flick it a few times to make sure its dry and spinning freely. using a q tip and rubbing alcohol swab the bearing seat on both yoyo halves very thoroughly until q tip remains clean after swabbing. reassemble. fresh string. avoid lube
Just switch bearings. Maybe the bearing is just shot. If it’s clean it should spin when you flick it with your finger. Is the string double wrapped on the bearing? People who do looping sometimes double wrap the string around the bearing for more responsiveness. The bearing might just be garbage. It’s good to have extras around. I usually buy a pack of them.
I had to clean my Shooting Star bearing a few times to get it clean when I got it. Mine just became scratchy and responsive on it’s own. They told me they use YYF Dark Matter in a message and apparently that’s graphite and it clumps up. I’d try cleaning it some more maybe if you are willing. I used Acetone and an air compressor after soaking it.
I have given up on mineral spirits and moved to lighter fluid. Have never done Dawn like another poster suggested, but that is going to remove any grease for sure. When I clean, I then stuff the bearing on to a pencil and spin it. If I do not get 60 seconds, I repeat.
