When the factory rubber bushings are shot out this is the fix , I put this on my little cousins 2012 kx250f and made his bars stay straight and stay tight. Please note that this will add a little more vibration to stock bars
This plug looks cool and the magnet works, but its made of aluminum. You don't want to put that in, because you can accidentally strip the soft metal too easily. Stick with the OEM plug or a different product.
